摘要
There occur two types of rock crystals in Emeishan basalt from Meigu County, Sichuan province, amethyst and the “trichroic” rock crystal of the first ore-forming stage in vesicles of basalt and the light color rock crystal of the second ore-forming stage in interlayer-gliding (faulted) fissures or vugs of basalt. The iron oxides in rock crystals are specularite, hematite and lepidocrocite. This study has important significance to understand the growth mechanism, the growth rate, the variation of thermodynamics under the given condition in ferrous oxide and the differentiation of mineralization stage.
