A Tectonic Twist: How Gibraltar Could Close the Atlantic Ocean
The Earth’s lithosphere is divided into multiple tectonic plates, which are continuously moving. This movement leads to the formation and fragmentation of supercontinents, alongside the…
The Geological Society of America (GSA) is a scholarly organization dedicated to the advancement of the geosciences. Founded in 1888, the GSA serves members from academic institutions, government, and industry around the world by promoting the study of geological processes, encouraging professional cooperation among scientists, and disseminating research findings through its meetings, publications, and educational programs. The society publishes a variety of scientific literature, including the prominent journal Geology, and organizes annual meetings that attract thousands of geoscientists who share research, network, and discuss trends in the field. The GSA also provides grants and awards to support research and recognizes outstanding contributions to the geosciences with prestigious awards.

A 6-mile (10-kilometer) asteroid hit Earth 66 million years ago, triggering the extinction of the dinosaurs. According to new evidence, the Chicxulub impact also triggered…
Ancient microorganisms found in halite may have implications for search for both terrestrial and extraterrestrial life. Primary fluid inclusions in bedded halite from the 830-million-year-old…
Several dozen small impact craters, 10–70-m in size, have been discovered in southeastern Wyoming. A team of U.S. and German geoscientists found these ancient craters…
Rift Valley lakes within eastern Africa range from freshwater to highly alkaline systems and are homes to diverse ecosystems. These Rift Valley lakes are also…
International drilling efforts over the last decades into the seafloor have provided increasing evidence for the existence of an extensive deep biosphere below the seafloor….
