New evidence of the Sahara's age

Researchers found layers of ancient African dust in volcanic rocks and dune sands on Canary Islands, dating back to 4.8-2.8 million years ago. The findings agree with deep-sea sediments and suggest the Sahara Desert has taken breaks, with wetter periods interspersed with arid times.

Trinity geologists re-write Earth's evolutionary history books

Researchers found evidence of chemical weathering and soil formation at least 60 million years earlier than previously thought. This discovery suggests that oxygen-producing species existed on Earth 3 billion years ago, paving the way for complex life to evolve.

New sources found for accumulated dust on Chinese Loess Plateau

Researchers found zircon crystals with ages matching those from western source sites, indicating a dramatic shift in atmospheric winds. The study improves climate modeling by suggesting alternating northwesterly and westerly sources for loess during glacial periods.

January-February 2011 GSA Bulletin highlights

This issue of GSA Bulletin explores river geomorphology, submarine landslides, and paleoclimatic analysis. Researchers examine the impact of a dome-building eruption on downstream channel aggradation in Oregon, as well as the age and genesis of the Sangamon/Loveland complex in the Lower Mississippi Valley.

African dust caused red soil in southern Europe

Researchers found African mineral dust from the Sahara and Sahel regions was the main contributor to forming reddish soils in Mediterranean regions such as Mallorca and Sardinia. The study also revealed that underlying rock contributed to soil formation.

September/October 2009 GSA Bulletin highlights

The GSA Bulletin highlights studies on the Lesser Himalaya, southern Chinese Altai Range, and San Ysidro fault in New Mexico. Researchers unravel tectonic processes responsible for building the Himalayan foothills and provide new insights into faulting mechanisms and magmatic evolution of Western Amazonia.

Ancient South African soils point to early terrestrial life

Researchers found ancient soil in South Africa with organic carbon dating back 2.6-2.7 billion years, indicating microbial mats developed on land during rainy seasons. The findings suggest the development of terrestrial biomass more than 1.4 billion years earlier than previously reported.
