(Geological Society of America) Registration is open for The Geological Society of America's Annual Meeting & Exposition, to be held Oct. 22-25 2017 at the Washington State Convention Center in Seattle, Washington, USA.
(Geological Society of America) One of the main types of fossil used to understand the first flowering plants (angiosperms) are charred flowers. These charcoals were produced in ancient wildfires, and they provide some evidence for the types of plants that grew millions of years ago. However, when fires burn they not only produce charcoal, but they also destroy it.
(Geological Society of America) A field guide in conjunction with GSA's Rocky Mountain Section meeting offers five field trips that explore the structural geology, sedimentology, and paleontology near Calgary, as well as examining the relationship of the geology to the regional petroleum and mining industries.

(Geological Society of America) Geoscientists in the North American Rocky Mountain region and beyond will convene on June 9-10 in Calgary, Ontario, Canada, to discuss new science, expand on existing science, and explore the unique geologic features of the region. Show More Summary
(Geological Society of America) If you ever fly from L.A. to San Francisco, California, you may notice the Gabilan Mesa off to the east as you begin your descent into San Francisco International Airport. If you look carefully, you might...Show More Summary
If I seem to be missing in action, it would be because I've been stuck on planes and in airports on my way to the conference and field trips of the Cordilleran Section of the Geological Society of America. Just my luck that they happen to be meeting in Hawai'i this year. Show More Summary
(Geological Society of America) Rare earth elements have become increasingly important for advanced technologies, from cell phones to renewable energy to defense systems. Mineral resources hosted in heavy mineral sand deposits are especially...Show More Summary
(Geological Society of America) Geoscientists from the North American Cordilleran region will convene in Honolulu, Hawai'i, on May 23-25, to discuss new science, expand on existing science, and explore the unique geologic features of the region. Show More Summary
(Seismological Society of America) Annemarie Baltay, a research geophysicist at the US Geological Survey in Menlo Park, has been honored with the Seismological Society of America's (SSA) 2017 Charles F. Richter Early Career Award for her important contributions bridging the gap between seismology and earthquake engineering.
(Seismological Society of America) The Seismological Society of America (SSA) will present its highest honor, the 2017 Harry Fielding Reid Medal, to US Geological Survey emeritus geologist George Plafker, for his transformative work on megathrust earthquakes in subduction zones, places where two tectonic plates meet, with one riding over the top of the other.
(Geological Society of America) Cretaceous climate warming led to a significant methane release from the seafloor, indicating potential for similar destabilization of gas hydrates under modern global warming. A field campaign on the remote Ellef Ringnes Island, Canadian High Arctic, discovered an astounding number of methane seep mounds in Cretaceous age sediments.
(Seismological Society of America) In a presentation at the 2017 Seismological Society of America's (SSA) Annual Meeting, US Geological Survey seismologist Andreas Llenos will discuss lessons learned from the 2016 Bombay Beach swarm, in particular the challenges in modeling swarms and communicating their risk to the public.
(Geological Society of America) In their study published in Lithosphere this week, James Kessler and colleagues examine the geology of a scientific borehole drilled into the Snake River Plain, Idaho, USA, to investigate the potential for geothermal energy at depth. Show More Summary
(Geological Society of America) Boulder, Colorado, USA: Climate is changing -- there should be zero doubt about this circa 2017. The outstanding issue for the geoscience community has been how we best portray to this to the public. In...Show More Summary
(Geological Society of America) The Marias River canyon geoecosystem and its associated archaeological resources provide an excellent example of the complex interplay among geology, plant ecology, ungulate niches, and human activities on the landscape during late Holocene time. Show More Summary
(Geological Society of America) A new field guide in conjunction with GSA's Southeastern Section meeting offers seven field guides that explore the diverse geology of Virginia from its Appalachian highlands to the Atlantic shore. The...Show More Summary
(Geological Society of America) Geoscientists from the southeastern United States and beyond will convene in Richmond, Virginia, on March 30-31 to discuss new science, expand on existing science, and explore the unique geologic features of the region. Show More Summary
(Geological Society of America) The end-Paleozoic witnessed the most devastating mass extinction in Earth's history so far, killing the majority of species and profoundly shaping the evolutionary history of the survivors. Echinoderms are among the marine invertebrates that suffered the most severe losses at the end-Permian extinction.
(Geological Society of America) Shale gas has changed thinking about fossil energy supplies worldwide, but the development of these resources has been controversial. Activists have made claims that hydraulic fracturing may contribute to climate change, threaten groundwater resources, and pose risks to terrestrial and aquatic ecosystems, and human health.
(Geological Society of America) A multi-year study of Egypt's Nile Delta places the country's major breadbasket at serious risk. The soil-rich delta evolved as the result of natural conditions involving the Nile's fresh water flow and transport of sediment northward from Ethiopia, across the Sudan and Egypt to the Mediterranean.
