Geology

An international group of scientists has proposed a start date for the dawn of the Anthropocene - a new chapter in the Earth's geological history.

A definitive geological timeline shows that a series of massive volcanic explosions 66 million years ago spewed enormous amounts of climate-altering gases into the atmosphere immediately before and during the extinction event that claimed Earth's non-avian dinosaurs, according to new research from Princeton University.

A new study is helping to answer a longstanding question that has recently moved to the forefront of earth science: Did our planet make its own water through geologic processes, or did water come to us via icy comets from the far reaches of the solar system?

The rate at which carbon emissions warmed Earth's climate almost 56 million years ago resembles modern, human-caused global warming much more than previously believed, but involved two pulses of carbon to the atmosphere, University of Utah researchers and their colleagues found.

The Atlantic Ocean at mid-depths may have given out early warning signals – 1,000 years in advance - that the last Ice Age was going to end, scientists report today in the journal Paleoceanography.

The rate at which carbon emissions warmed Earth's climate almost 56 million years ago resembles modern, human-caused global warming much more than previously believed, but involved two pulses of carbon to the atmosphere, researchers have found.

An ancient meteorite and high-energy X-rays have helped scientists conclude a half century of effort to find, identify and characterize a mineral that makes up 38 percent of the Earth.

A team of researchers from Caltech and the China Earthquake Administration has discovered an ancient, deep canyon buried along the Yarlung Tsangpo River in south Tibet, north of the eastern end of the Himalayas.

If you want to see into the future, you have to understand the past. An international consortium of researchers under the auspices of the University of Bonn has drilled deposits on the bed of Lake Van (Eastern Turkey) which provide unique insights into the last 600,000 years.

This at least is what the geologist Prof. Dr. Ulrich Schreiber and the physico-chemist Prof. Dr. Christian Mayer of the University of Duisburg-Essen in Germany are convinced of.

New analysis of geologic history can potentially solve the riddle of the ‘Cambrian explosion’.

The research conducted by Ryan McKellar’s sounds like it could of come straight out of Jurassic Park: he studies pieces of amber found buried with dinosaur skeletons. However, instead of re-creating dinosaurs, McKellar uses the tiny pieces of fossilised tree resin to study a world where the extinct animals thrived.
