The Evolution of Mineral Evolution | SpringerLink
The qualitative concept of mineral evolution was developed over a two-year interval, beginning on 6 December 2006. Theoretical biologist Harold Morowitz, who had long been speculating about origins-of-life scenarios (Morowitz 2002, 2004) asked Robert Hazen about the liklihood that clay minerals were present on Earth during the Hadean …

Crystal structure and compression of ruby to 46 kbar
Crystal structures and lattice constants have been determined for ruby at hydrostatic pressures up to 46 kbar using a gasketed opposed‐anvil diamond cell on a four‐circle diffractometer. The measured compressibility is slightly anisotropic, having a value of 1.36±0.03×10 −4 kbar −1 parallel to c and 1.22±0.03×10 −4 kbar −1 ...
