“…Previous studies have characterized the many differences between samples and examined the thermal expansion of pyrite (Chrystall, 1965;Smith, 1942), and there have been several experimental and computational studies conducted at high pressure (both static and dynamic) to determine the Raman spectra, electronic structure, elasticity, and equation-of-state of pyrite (Blanchard et al, 2005;Le Page and Rodgers, 2005;Kleppe and Jephcoat, 2004;Sithole et al, 2003;Merkel et al, 2002;Ahrens and Jeanloz, 1987;Fujii et al, 1986;Chattopadhyay and von Schnering, 1985;Drickamer et al, 1967). In addition, studies have determined the single-crystal elastic constants of pyrite (Benbattouche et al, 1989;Simmons and Birch, 1963;Prasad and Wooster, 1956).…”
