摘　　要：红柱石矿主要三大成因类型(区域变质型、接触变质型、热液蚀变型(也叫次生石英岩型))在宝鸡地区都有,三大类型矿石中的主要矿物都是红柱石、石英、云母。次要矿物和其它少量矿物因类型差异不同而不同,其中区域变质型常含有斜长石、蓝晶石、石榴子石;接触变质型常含量有斜长石、角闪石、钙铝榴石;热液蚀变型(也叫次生石英岩型)常含有少量刚玉,红柱石多呈隐晶质状,肉眼不易辩认,但品位常常较高。宝鸡特殊的成矿地质条件是未来寻找红柱石矿最有潜力的地区之一。Andalusite ore the three major types （ regional-metamorphic, contact metamorphism and hydrothennal alteration （ also called secondary quartzites） ） in Baoji area there are three types of ore minerals are mainly of Andalusite, quartz and MICA.Secondary minerals and other small amounts of mineral types vary, among them regional metamorphism often contain plagioclase, and kyanite, Garnet ; Contact-metamorphic content of plagioclase, hornblende, calcium aluminium Garnet ; Hy- drothermal alteration （also called secondary quartzites） often contain a small amount of corundum, Andalusite are crypto- crystalline, the naked eye is not easy to identify, but taste is often higher.Baoji special geological conditions is looking for Andalusite ore in the future one of the most promising areas.
