The deep Earth oxygen cycle addresses the origin and long-term exchange of oxidized species between the mantle and exosphere and creates the geochemic…
Carbonate melts produced by partial melting of the carbonated mantle or by liquid immiscibility from mantle-derived silicate melts provide insights in…
An international team of researchers has chosen the location which best represents the beginnings of what could be a new geological epoch, the Anthropocene. The Anthropocene Working Group have put forward Crawford Lake, in Canada, as a Global Boundary Stratotype Section and Point (GSSP) for the Anthropocene. A GSSP is an...
University of Texas at Austin has describing the first known Jurassic vertebrate fossils in Texas.The weathered bone fragments are from
Pallasite meteorites contain evidence for vastly different cooling timescales: rapid cooling at high temperatures (K/yrs) and slow cooling at lower te…
An international research team has discovered that a subduction zone's age affects the ability for it to recycle water between the Earth's surface and its inner layers. The more mature the subduction zone, the bigger the water storage capacity.
An international team has, for the first time, accurately determined the age of the East Anatolian fault, allowing geologists to learn more about its seismic history and tendency to produce earthquakes.
A study led by Brown University researchers offers new insights into how water from melting ice could have played a recent role in the formation of ravine-like channels that cut down the sides of impact craters on Mars.
A vast expanse of the Indian Ocean is a staggering 100 meters lower than the global average sea level because of a major dip in Earth’s gravity. Scientists now think they know the cause
The Sistema Huautla in Oaxaca is the 10th deepest cave on Earth, and a explorers with a 2023 expedition to map the system have added over 700 feet to its length.
The first ever 3D seismic imaging of a subducting seamount shows a previously unknown sediment trail in Earth's crust off the coast of New Zealand. Scientists think the sediment patches help release tectonic pressure gradually in slow slip earthquakes instead of violent tremors. The findings will help researchers search for...
This 25-minute movie illustrates the geologic evolution of Colorado through time, and premiered at the Opening Ceremony of the AAPG Convention in Denver on 3...
About 12% of 230 groundwater sites sampled in the Grand Canyon region over 45 years show arsenic concentrations greater than the U.S. Environmental Protection Agency Maximum Contaminant Level for drinking water, according to a new U.S. Geological Survey report.
Humans have been fascinated by Mars probably since the first of the species turned their gaze to the night sky. Space exploration today attests to that continuing fascination.
How did the Andes – the world's longest mountain range – reach its enormous size? This is just one of the geological questions that a new method developed by researchers at the University of Copenhagen may be able to answer. With unprecedented precision, the method allows researchers to estimate how Earth's tectonic plates...
Do not touch Pele's hair for your own safety.
A new study challenges longstanding beliefs about Earth's stable cratons, revealing that they have undergone repetitive deformation beneath their crust since formation. Contrary to previous theories, the study found that the mantle keels, once thought to be buoyant and stable, are dense and subject
