When he came to the Bureau of Economic Geology in 1980, Martin Jackson was a hard-rock kind of guy. He was grew up in what was then Rhodesia (today, Zimbabwe), prospected for minerals there and in South Africa and Namibia, studied the metamorphic history of Precambrian gneisses in the Forbidden Area of the Namib Desert…

A new study correlates a series of small earthquakes near Snyder, Texas between 2006 and 2011 with the underground injection of large volumes of gas, primarily carbon dioxide (CO2) — a finding that is relevant to the process of capturing and storing CO2 underground. Although the study suggests that underground injection of gas triggered the…

So much oil and water is being removed from South Texas’ Eagle Ford Shale that the activity has probably led to a recent wave of small earthquakes, according to a study that appears in the online edition of the journal Earth and Planetary Science Letters. The peer-reviewed study’s authors suggest that taking oil and water out…

Los Angeles Times, July 13, 2013 Featuring: Ian Dalziel Ancient volcanoes discovered deep in the ocean off Antarctica may explain a climate mystery critical to predicting Earth’s fate as humans pump more carbon dioxide into the atmosphere. University of Texas geologists dredging thousands of feet below the surface of the central Scotia Sea off the…

A team of scientists led by Ian Dalziel from the Institute for Geophysics has found geologic evidence that casts doubt on one of the conventional explanations for how Antarctica’s ice sheet began forming. The team discovered an ancient volcanic arc that might have prevented the creation of the Antarctic Circumpolar Current.

LiveScience, July 10, 2013 Featuring: Dusty Schroeder, Don Blankenship A sprawling network of low-lying canals, similar to a swamp, hides under Antarctica’s Thwaites Glacier, a new study finds. The fast-flowing Thwaites Glacier is one of the largest ice streams in West Antarctica. Scientists think Thwaites could significantly retreat in the next 20 years, adding to global sea level…

An international team of 34 scientists sets sail today aboard the scientific ocean drilling vessel JOIDES Resolution to collect sediments in the Gulf of Alaska and investigate the interactions between long-term global climate change and the simultaneous growth of mountain belts. The team is co-led by Sean Gulick, research associate professor at The University of Texas…

A tectonic plate that disappeared millions of years ago has turned up in Central California and Mexico. New research from Brown University found that part of the Baja region of Mexico and part of central California near the Sierra Nevada mountains sit upon slabs of this long-lost plate. It’s a big breakthrough in how we…

The Geological Society of London, the world’s oldest and one of its most prestigious geological organizations, has announced it will award medals to two scientists working at the Bureau of Economic Geology, Martin P. A. Jackson, senior research scientist, and Christopher Jackson, senior research fellow. Martin Jackson will receive the William Smith Medal, presented for…

Researchers from Amherst College and The University of Texas at Austin have described a new technique that might one day reveal in higher detail than ever before the composition and characteristics of the deep Earth.
