Meteorite strikes may create unexpected form of silica – Science Daily
New research examining the crystal structure of the silica mineral quartz under shock compression is challenging longstanding assumptions about this ubiquitous material.
When a meteorite hurtles through the atmosphere and crashes to Earth, how does its violent impact alter the minerals found at the landing site? What can the short-lived chemical phases created by these extreme impacts teach scientists about the minerals existing at the high-temperature and pressure conditions found deep inside the planet?New work led by Carnegie’s Sally June Tracy examined the crystal structure of the silica mineral quartz under shock compression and is challenging longstanding …
