Tiny bits of quartz record the intensity of fires from hundreds or even thousands of years ago, potentially offering new ways to study historic fires and how heat affects soil.
Large scale molecular dynamics simulations unravel the coupled processes at work during fracturing and flow of carbon dioxide and water in quartz grains at the nanoscale.
The discovery of tridymite in Mars’s Gale Crater triggered debate about the rare mineral’s origins. A research team recently suggested a scenario with explosive implications.
Large earthquakes are necessarily punctuated by some degree of strength recovery, such as “fault healing”, but does quartz cementation during fluid-fault interactions facilitate that process?
The first comprehensive analysis of what the sarsen stones are made of came about with new technology—and good old-fashioned luck.
New research on the geochemistry of Canary Islands paleosols shows that the Sahara has been an arid dust producer for at least 4.8 million years.
Scientists have long interpreted shocked quartz as definitive evidence of a past meteorite impact, but the shock wave caused by lightning striking granite also produces this distinctive feature.
Formation of nanometer-scale quartz beads could promote linear “slickenline” patterns and facilitate fault movement.
Using Puerto Rico's Luquillo Mountains as a case study, scientists use the region's geological history to study how knickpoints—areas where there's a sharp change in the river's slope—move over time.
A comparison of water content in undeformed and deformed quartz indicates that grains may change shape via weakening processes that cannot be duplicated in laboratory experiments.
