“The Asian Monsoon and Its links to Cenozoic Orogenesis”
Abstract:
The Asian monsoon represents the most dramatic proposed example of how the solid Earth may cause changes in atmospheric and oceanic circulation and trigger climate change on a regional or even global scale. It has been suggested for several years now that rising of the Tibetan Plateau has caused the monsoon to strengthen around 8 Ma yet modeling also highlights the potential importance of the Himalayan barrier and the retreat of shallow seas from central Asia in shaping regional climate. Theoretical models also suggest that a strong monsoon would drive rapid exhumation in the Himalaya. However, this does not correlate with the 8 Ma climate event because exhumation is known to have started by around 23 Ma, although formation of the Lesser Himalayan duplex is known to have started in the Late Miocene. Are models or observations at fault? It is noteworthy that the best 8 Ma monsoon proxies are driven by wind and upwelling, not rainfall or run-off making their interpretation more complex than was first believed. Recent investigations of cores for seawater salinity and for chemical weathering intensity from the South China Sea now suggest that 8 Ma was a time of regional drying and that monsoon intensification likely happened around the start of the Miocene ~24 Ma. This change is broadly in line with ODP data from the Bay of Bengal and from industrial and DSDP boreholes in the Arabian Sea. In this scenario, rising of the plateau following the start of India-Asia collision at ~50 Ma caused the monsoon to strengthen after it reached a critical threshold at approximately half its present size. The onset of stronger summer rains then caused faster focused erosion along the Himalaya front, allowing the Greater Himalaya to begin their exhumation and shedding large volumes of clastic material into the Indian Ocean, peaking around the time of the Middle Miocene Climatic Optimum at 16 Ma. Scientific drilling in 2014 and 2015 now targets the period of initial monsoon intensification, which is poorly defined and these expeditions seek to demonstrate whether the monsoon operated in a relatively uniform fashion across Asia or whether there are major differences between south, southeast and eastern Asian marginal seas.

Hydrologic Influences of the Blanco River on the
Trinity and Edwards Aquifers, Central Texas
Abstract:
The Blanco River of central Texas provides an important hydrologic link between surface and groundwater as it traverses two major karst aquifer systems—the Trinity and Edwards Aquifers. The Blanco River is characterized by alternating gaining and losing stretches due to the presence of springs that discharge water into the river and swallets that drain water from the river. Trinity units outcrop in the western part of the study area, and Edwards units outcrop in the eastern part of the study area. Normal faulting along the Balcones Fault Zone has juxtaposed the older, underlying Trinity units against the Edwards units. The region consists primarily of Cretaceous limestone, dolomite, and marls. One of the more significant springs along the Blanco River is Pleasant Valley Spring. During below-average flow conditions, Pleasant Valley Spring becomes the headwaters of the Blanco River even though the headwaters, under wet conditions, are about 50 km upstream. Water that enters the Edwards Aquifer from the Blanco River can eventually discharge at both San Marcos Springs to the south and Barton Springs to the north. Tracer tests have confirmed flow to both springs under drought conditions. During periods of extreme drought, when other recharging streams are dry, the Blanco River can provide enough water to the Edwards Aquifer that will help maintain flow at Barton Springs. Some of the water recharging the Trinity Aquifer enters a deep flow system that has been penetrated by monitor and water-supply well at depths of about 400 m on the east side of the study area. In this area, low-permeability units of the Upper Trinity provide hydraulic separation between the water-bearing Middle Trinity and the overlying Edwards. Potentiometric and geochemical data suggest that water encountered in these deep Middle Trinity units comes from recharge areas along the Blanco River where the units are exposed at the surface. In the western part of the study area increasing rates of pumping from the Trinity Aquifer are reducing heads in the aquifer and are subsequently reducing springflows (such as from Jacob’s Well and Pleasant Valley Spring) that sustain the Blanco River. Decreasing flow in the Blanco River can lead to less recharge to the Edwards Aquifer and less discharge from San Marcos and Barton Springs. A better understanding of these aquifer systems and how they are influenced by the Blanco River is important for management of groundwater in an area undergoing significant population growth.

“Using Messy Seismicity to Investigate Earthquakes and Plate Boundary Dynamic”
Abstract:
Tectonic tremor, a messy seismic signal characterized by enduring 1-10 Hz signals, is observed beneath the locked zone of many faults. In subduction zones, it is often accompanied by slow slip, an intermediate mechanism for accommodating plate motion between a megathrust rupture and stable sliding. While it is evident these phenomena play a critical role in relieving stress on the plate interface, the nature of these signals makes tracking them difficult, however, and a clear understanding of the processes controlling their behavior remains elusive. Here I’ll try and make the case that tracking this behavior is both interesting and important by presenting an overview of we do and don’t know, how it relates to hazards, and what it means for the physics of earthquakes and plate boundary dynamics.

Join the Jackson School Friends and Alumni Network for an update on cutting edge research from Dr. Gregory Frebourg from the Bureau of Economic Geology
Advances in Mudrock Systems Research: In recent years, as the unconventional production of hydrocarbons has boomed, geologists have realized the need for proper characterization of organic-matter-rich mudrocks in order to maximize exploration and exploitation and lower their inherent risks. Before the advent of unconventional hydrocarbon exploitation, organic-matter-rich mudrocks were only of interest as hydrocarbon sources or traps. Limited studies were made on mudrocks, often limited to confirming their potential. In contrast, conventional reservoirs have undergone decades of detailed study directed at understanding their depositional dynamics, and useful methods have been developed for their correlation. Lacking alternatives, geoscientists have used such tools in attempts to characterize mudrock systems. Although these methods may be of general use, they fail to adequately define the character of mudrocks. For successful unconventional exploitation, such obsolete paradigms need to be re-evaluated. This talk will present recent breakthroughs in the understanding mudrock systems and exemplify them using the very Texan Eagle Ford Formation.

Borehole Imaging at Baker Hughes
Abstract:
Borehole Imaging was an evolutionary step-change from the dipmeter technology of the 80s and early 90s. It is around 20 years since Baker Hughes launched their first wireline borehole imagers, and from that time there have been multiple advances in imaging technology. Imaging tools are now routinely employed in both water and oil-based mud systems, on wireline and on LWD. Most major and independent oil and gas operators are aware of the basic capabilities of these tools, but not all have a complete understanding of the range of interpretation possibilities they provide. This overview will discuss the principal tool types available in industry and touch on how such tools can help us to gain invaluable information from the subsurface.

“Locking, Mass Flux and Topographic Response at Plate Boundaries – The Chilean Case”
Abstract:
On the long term, convergent plate boundaries have been shown to be controlled by either accretion/underplating or by subduction erosion. Vertical surface motion is coupled to convergence rate – typically with an uplift rate of the coastal area ranging from 0 to +50% of convergence rate in accretive systems, and -20 to +30% in erosive systems. Vertical kinematics, however, are not necessarily linked to horizontal strain mode, i.e. upper plate shortening or extension, in a simple way. This range of kinematic behaviors – as well as their acceleration where forearcs collide with oceanic ridges/plateau – is well expressed along the Chilean plate margin.
Towards the short end of the time scale, we here find that fault motion as well as vertical motion may exhibit reversal of motion from the preseismic to the postseismic stage, and may show extensional as well as compressional deformation to temporally coexist next to each other. This complexity is suggested to be chiefly controlled by seismic cycle related forearc bending and unbending causing fault triggering in the upper plate, a mechanism unique to forearcs. In addition, the short term deformation time end appears to exhibit a close correlation with the frictional properties and geodetic locking at the plate interface. Corroborating analogue experiments of strain accumulation during multiple earthquake cycles, forearc deformation and uplift focus above the downdip and updip end of seismic coupling and slip and are each related to a particular stage of the seismic cycle, but with opposite trends for both domains. Similarly, barriers separating locked domains along strike appear to accumulate most upper plate faulting interseismically. Hence, locking patters are reflected in topography. From the long-term memory contained in the forearc topography the relief of the Chilean forearc seems to reflect long term stability of the observed heterogeneity of locking at the plate interface. Finally, the nature of locking at the plate interface controlling the above kinematic behavior appears to be strongly controlled by the degree of fluid overpressuring at the plate interface suggesting that the hydraulic system at the interface takes a key role for forearc response.

The meltwater generated from these glaciers can take several paths, ultimately discharging into coastal waters or stored in closed-basin lakes. Ice-marginal lakes are a common but poorly understood feature in many glaciated regions, including Greenland. The lakes receive freshwater input from a combination of subglacial, supraglacial, terrestrial and meteoric sources, and a subset periodically drain, resulting in the rapid discharge of large volumes of water downstream (glacial lake outburst floods – GLOFs). In the case of drainages under adjacent marine terminating glaciers, GLOFs can deposit large amounts of sediment, nutrients, and freshwater directly into coastal waters and fjords. Lake Tininnilik, a large (~40 km2) ice-marginal lake that forms along Saqqarliup Glacier in west Greenland, drains ~2 km3 on quasi-cyclic decadal timescales into Saqqarleq Fjord to the north. For this talk, I will discuss the first comprehensive biogeochemical analysis of Lake Tininnilik and its potential influence on coastal primary productivity, including its major and minor nutrient stoichiometry and microbial composition. As the climate continues to warm, GLOFs are expected to become more frequent in Greenland. Therefore, it is imperative that we understand how these events can impact coastal community resilience. |

Speaker: Crispin Little, Professor, School of Earth and Environment, University of Leeds Host: Rowan Martindale Title: Biotic response to environmental perturbations in the Pliensbachian and Toarcian stages of the Lower Jurassic Abstract: The Lower Jurassic period was characterized by instability in global climate, with alternating greenhouse and icehouse states, and episodes of widespread oxygen depletion in the shallow marine environment. These episodes of oxygen depletion are marked by frequent intervals of increased organic carbon preservation in shallow marine sediments. The Pliensbachian stage of the Lower Jurassic was characterised by significantly cooler global temperatures than the preceding Sinemurian, and the following Toarcian stages, and ended with an extinction event (notably for ammonites) at the Pliensbachian-Toarcian boundary (Pl-To) ca. 184.2 Ma. About one Myr later the Toarcian Oceanic Anoxic Event (T-OAE) is characterized Corg rich black shale successions, particularly well developed in sedimentary basins in NW Europe, which display a negative ?13Corg excursion of -5 to -6‰, lasting 0.5 to 1.5 Myr. This excursion has been tied to a disruption of the global exogenic carbon cycle, but the ultimate source of the injected 12C is a matter of debate, with suggestions including methane hydrates, thermogenic methane produced by volcanism in the Karoo-Ferrar Large Igneous Province (LIP), wetlands, and permafrost destabilisation. The onset of the T-OAE in many (but importantly not all) sections is intimately linked to an extinction event that especially impacted the marine benthic macrofauna, but left the nekton largely unaffected. The recovery from this event is not well studied, but in one site, the Cleveland Basin of North Yorkshire, UK, although species richness recovered markedly as soon as environmental conditions ameliorated, other metrics of functional diversity and community structure did not attain pre-extinction levels until much later, some five million years after the extinction event. The talk will be of interest to those working on macroevolution, paleontology, and the effect of large scale climate change on marine ecosystems. |

Master\'s Thesis PresentationsApril, 19 2024Time: 2:00 PM - 5:00 PMLocation: JGB The Master of Science (MS) degree at the Jackson School of Geosciences is considered to be the professional degree for a career in the Geosciences. This degree is the foundation for students pursuing employment in the petroleum industry, environmental and hydrogeological fields, state and federal government agencies, and other related geoscience fields. Some students also use the MS degree as preparation for pursuing a Ph.D. The Energy & Earth Resources Interdisciplinary program provides the opportunity for students to prepare themselves in management, finance, economics, law and policy leading to analytical and leadership positions in resource-related fields. The private sector and government organizations face a growing need for professionals that can plan, evaluate, and manage complex resource projects, commonly international in scope, which often include partners with a variety of professional backgrounds. As requirements for these degrees, students must present a professional talk on Master\'s Thesis Presentations. |
