A US-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 ...

Blacksburg, Va. -- Feldspars, which make up 60 percent of all the rock on the earth's surface, were little understood as recently as the 1950s. Prof. Helen Megaw of Cambridge University was the expert ...

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 ...

Identification of minerals founded on BSE signal segmentation can be challenging as some minerals have comparable BSE intensities. Advanced Mineral Identification and Characterization System (AMICS) ...
