Simulating meteorite impacts in the lab

A U.S.-German research team has simulated meteorite impacts in the lab and followed the resulting structural changes in two feldspar minerals with X-rays as they happened. The results of the experiments at DESY and at Argonne ...

Scientists discover new forms of feldspars

In high-pressure experiments, scientists have discovered new forms of the common mineral feldspar. At moderate temperatures, these hitherto unknown variants are stable at pressures of Earth's upper mantle, where common feldspar ...

Geological fingerprinting of volcanic ash

Volcanic ash consists of tiny particles containing minerals and glass. LMU researchers have now used a new analytical technique based on quantitative chemical analysis under a scanning electron microscope to link their surface ...
