Two-billion-year-old salt rock reveals rise of oxygen in historical environment
Salts left over from historical seawater reveal new details about the oxygenation of the Earth’s environment greater than 2 billion years in the past. Geology News — ScienceDaily
Worldwide research determine the method of rock fashioned by meteors or nuclear blasts
Scientists have made a mannequin to map out the phases through which silica (SiO2) transforms into coesite, by analyzing how the inelastic scattering of sunshine amongst molecules modifications in line with strain variation. Geology News — ScienceDaily
Mass of warm rock rising beneath New England
Slowly but steadily, an enormous mass of warm rock is rising beneath part of New England, although a major volcanic eruption isn’t likely for millions of years, a new study suggests. The research is unprecedented in its scope and challenges … Continue reading

Newly discovered volcanic rock minerals may offer new insights into earth’s evolution
Scientists have found evidence showing that komatiites, or three-billion-year old volcanic rock found within the Earth’s mantle, had a different composition than modern ones. Their discovery may offer new information about the first one billion years of Earth’s development and … Continue reading
Researcher Unearths Hottest Rock on Record

Climate Change Won’t Stop Stony Corals From Making Rock
Stalactite-lined Agatized Coral from Withlacoochee River, Lowndes Co., Georgia New research suggests stony corals may fare better under the acidic ocean conditions caused by climate change than once thought. “The bottom line is that corals will make rock even under … Continue reading

Geoscientists Find Explanation for Puzzling Pockets of Rock Deep in Earth’s Mantle
Tiny regions of compositionally distinct rock (red material, known as ultra-low velocity zones), collect at Earth’s core-mantle boundary (tan surface), nearly halfway to the center of our planet. Small accumulations of this distinct rock collect near the margins of large … Continue reading
Puzzling pockets of rock deep in Earth’s mantle explained
The boundary between Earth’s core and mantle is home to isolated pockets of rock which scientists have been unable to explain up until now. Geology News — ScienceDaily
