英文摘要: Abstract(#br)A means for estimating pressures in natural samples based on both the coupled substitution (Na+) [1+] (Ti+ [VI] Si) [4+] =(M) [2+] (Al+Cr) [3+] , and the classic pyroxene-stoichiometry majorite-substitution into garnet at high-pressure, is derived for garnets with majoritic chemistry. The technique is based on a compilation of experimental data for different bulk compositions. It is compositionally and thermally robust and can be used to estimate pressures experienced by natural materials during formation of majoritic garnet. In addition, it can be used either retrospectively, or in new experimental studies to establish the pressures of crystallization of reaction...
