Hornblende - Wikipedia
Hornblende is a common constituent of many igneous and metamorphic rocks such as granite, syenite, diorite, gabbro, basalt, andesite, gneiss, and schist. It crystallizes in preference to pyroxene minerals from cooler magma that is richer in silica and water.
It is the principal mineral of amphibolites, which form during medium- to high-g…Wikipedia · CC-BY-SA 许可下的文字- 预计阅读时间：5 分钟
