一问题的提出黑云母是斑岩型铜-钼、铜-金矿床中广泛出现的矿物.它不仅是组成岩浆岩的一种岩浆成因矿物,而且在区域变质岩、热变质岩、热液蚀变岩中也可作为变质矿物出现.因此,搞清黑云母的成因及其发育强度,对斑岩铜矿的找矿是有意义的.几种成因的黑云母共存时,虽然其光学性质和化学成分有差异,但在某些情况下并不易区别.如横塘斑岩铜-钼矿化点,根据光
One issue raised Biotite is a widely occurring porphyry-type copper-molybdenum, copper - gold minerals.It is not only a magma-forming magmatic rocks, but also in the metamorphic rocks, metamorphic rocks, hydrothermal Variable rocks can also be used as metamorphic minerals.Therefore, to find out the cause of biotite and its development strength, the prospecting of porphyry copper ore is meaningful.While several causes of biotite coexistence, although its optical properties and Chemical composition differences, but in some cases is not easy to distinguish as Hengtang porphyry copper - molybdenum mineralization point, according to the light
