Major advances in the petrology and diagenesis of sedimentary rocks can also be tied to the program. Marine geology and geophysics has become an equally strong component through expertise across the Jackson School. The program was among the first to use multichannel seismic reflection techniques to understand the geologic history of continental margins around the world, and has pioneered the academic use of 3D seismic imaging for a variety of applications, from basin history and evolution to reservoir assessment. The program is currently focused in the areas of global change, geochemistry and diagenesis, sequence stratigraphy, seismic stratigraphy and geomorphology, surficial processes and sedimentary process modeling, and pore-scale to full field reservoir characterization.
The sedimentology/stratigraphy research community at JSG includes over 30 Ph.D. faculty, research scientists, and senior research scientists spread across the Department of Geological Sciences, Bureau of Economic Geology, and Institute for Geophysics. This group provides as wide a range of areas of research specialization as any similar program in the nation.
The Department of Geological Sciences group has core areas in seismic and sequence stratigraphic analysis of both clastic and carbonate systems, diagenesis and geochemistry of carbonates and clastics including extensive stable and radiogenic isotope labs, physical and numerical modeling of eolian, fluvial, and shallow to deep marine transport systems with an emphasis on the construction of sedimentary deposits, petrology, basin analysis, and the application of field, petrologic, chemical, and isotopic methods for studying chemical evolution of groundwater and ancient oceans.
The Institute for Geophysics is focused on large multidisciplinary research programs looking at 2D and 3D geophysical studies of stratigraphic evolution of marine and lacustrine basins worldwide. The sedimentology/stratigraphy group at the Institute makes use of a wide range of geophysical tools and datasets to attack problems of global geodynamics and climate change.
The Bureau of Economic Geology has research efforts in clastic and carbonate sequence stratigraphy, diagenesis and reservoir characterization, as well as seismic geomorphologic analysis of 3D seismic data, visualization of subsurface systems, mudrock depositional systems, basin-forming processes, and classic and digital outcrop analysis. They are working on basins and outcrop areas all over the world to answer questions concerning the fundamental processes that act to control rock properties in the subsurface.

|Innovative Detrital Provenance Studies - Double Dating PLUS (Graduate)|
A major thrust of my current research the development and application of more comprehensive isotopic detrital provenance tools. U-Pb on zircon is clearly the big work horse, but only goes so far and sometimes yields "no" useful info, e.g., if the source of the sediment is mostly recycled sediment. We have extensively pursued double dating of zircons by U-Pb and He, as zircon He ages yield very interesting insights into the thermal and tectonic history of the source terrane; often yielding very different insights than crystallization ages. The combination is powerful, but I think we can take things so much farther by combining double dating with other constrains. People have tried fission track (not precise enough), Hf/Hf (to get mantle separation model ages), etc., but what we want to do and are working on is really Double Dating ++, combining zircon U-Pb-He dating with a variety of other geochemical aspects to more comprehensive understand detrital provenance and improve paleo-tectonic reconstructions. For example, trace-element thermometry (Ti in zirc), REE on zircon (met vs mag origin), Hf/Hf (see above), oxygen isotopes, etc. and also to develop rutile in an analogous manner (e.g., Zr in rut thermometry, Cr/Nb ratio (mafic vs granulitic), REE, etc.). The sky is the limit and what can learn so much. The issue in part it, how much can a single grain tell us before it's gone? The project sounds very laboratory oriented, but it's really a combination of field and lab work. We have identified a few possible case study areas, e.g., Morocco; great exposures, long-lived and preserved record of basin deposition since the Precambrian. My group is already working on some case studies in NE Africa (Egypt), Sevier FTB and foreland basin, and the Colombian Llanos and Magdalena Basins.

The stage is mounted on an Olympus BX51 microscope with a 40X long-working distance objective, 2X image magnifier, and digital camera for image capture. The microscope also has capability for UV fluorescence petrography. Complementary facilities are available for reflected and transmitted light petrography and image capture.
|GeoMechanics Lab (BEG)|
In the GeoMechanics lab we study pore-scale sediment and fluid behavior. In this lab are components to make experimental specimens through resedimentation from either powdered sediment or extracted core material. Using the sediment, this lab can measure permeability and porosity with constant rate of strain experiments using any of our three load frames rated from 10,000 to 40,000 pounds or examine flow-through permeability and failure dynamics using a triaxial system. This lab is also capable of measuring permeability in tight gas shales using a series of Quizix pumps rated to 10,000 psi. The GeoMechanics lab is also spearheading the design of the ‘temperature 2 pressure’ (T2P) probe and a motion-decoupled hydraulic delivery system (MDHDS), a borehole tool capable of measuring in-situ temperature and pressure while de-coupled from the vessel and reporting data in real time. This probe will be deployed on an upcoming IODP (Integrated Ocean Drilling Program) expedition.

|Sub-Bottom Profiling Systems|
UTIG owns and maintains an integrated sonar system for use in conducting Compressed High Intensity Radar Pulse (CHIRP) subbottom profiling of the upper sediment layers of the ocean bottom or various fresh water systems. The 3200-XS system was purchased in 2007 from Edgetech Corp. of West Wareham, MA (see www.edgetech.com) and can be deployed in water depths from ~2 m to >300 m with an optimum towing height of 3-5 m above seafloor. Deployment and recovery of the towfish can be done by shipboard winches for shallower deployments or a larger UTIG-owned Electro-Hydraulic winch. Constraints on vessel size are dependent on shipboard winches capability of handling either the large (190kg SB-512i) or small (76 kg SB-216S) towfish. Power control, navigation, video display, data acquisition and data storage are all performed by one topside processing unit. The system can be powered by 18-36 VDC or 110/240 VAC (auto-ranging). The system is presently comprised of: 3200-XS topside computer processor, 4-transducer SB-512i towfish, 1-transducer SB-216s towfish, electro-hydraulic winch with 500 m of armored tow cable, 3 shallow water tow cables of 10, 25, and 50 m length, GPS navigation system.

|Center for Frontiers of Subsurface Energy Security|
CFSES is one of only two centers out of 46 EFRCs with focus on subsurface energy. Our goal is a scientific understanding of the physical, chemical, and biological subsurface processes from the very small scale to the very large scale so that we can predict the behavior of CO2 and other byproducts of the energy production that may need to be stored in the subsurface. At this aim, we need to integrate and expand our knowledge of subsurface phenomena across scientific disciplines using both experimental and modeling methodologies to better understand and quantify the behavior at conditions far from equilibrium. The unique aspect of our research is the approach of the uncertainty and of the complexity of the fluids in the geologic media from the molecular scale to the basin scale and their integration in computational tools to better predict the long term behavior of subsurface energy byproduct storage.
