黑云母是我国东北甲区合有銅矿化的奥长花崗斑岩中分布广的矿物之一。原生的黑云母經受到含矿热液作用后变化多,蝕变強,与銅矿化的关系也較紧密,因之对各种蝕变黑云母的物理性貭,化学組分,成因以及其相互关系的研究,不只是有助于闡述成矿作用和矿床成因,并且有利于对銅矿的探寻。以前在进行普查勘探工作时,曾提到过合銅矿化奥长花崗斑岩中富含有黑云母与钼矿化有关。但沒有进一步对黑云母进行研究。
Biotite is one of the widely distributed minerals in the coexistence of copper mineralization in the northeastern A district. After being exposed to ore-bearing hydrothermal fluids, the primary biotite has many changes and strong alteration, which is closely related to the mineralization of copper. Therefore, the physical properties, chemical composition, genesis, The study of the correlation not only helps to explain the mineralization and the genesis of the deposit, but also helps to explore the copper mine. In the past, during the census and exploration work, it was mentioned that the mineralization of biotite and molybdenum mineralization is related to the mineralization of the Changchang granite porphyry associated with copper mineralization. But no further research on biotite.
