个旧含锡花岗岩可分为褐帘石、屑石、磷灰石磁铁矿型与独居石磷钇矿、金红石(钛铁矿)型。这与巴尔苏索夫、石原舜三、查佩尔等人的矿物分类是吻合的。但是,其与矿化的关系却要复杂得多,很难说某型(系列)与锡矿化有关,而与另一型无关。笔者认为,两型(系列)均与锡矿化有关;生成两型付矿物因素之一是围岩条件及裂隙发育程度;而岩浆的同化作用与分异作用也有一定的影响。
Gejiu tin-containing granite can be divided into brown curtain stone, debris stone, apatite magnetite type and monazite xenotime, rutile (ilmenite) type. This is consistent with the mineral classification of Bausussuofu, Ishihara Shusan, Chapel and others. However, its relation to mineralization is much more complex. It is hard to say that a certain type (series) is related to tin mineralization and has nothing to do with the other type. In my opinion, both types (series) are related to tin mineralization; one of the two types of ore-forming factors is the surrounding rock conditions and the degree of fracture development; and the assimilation and differentiation of magma also have a certain impact.
