自六十年代以来,人们将云母类矿物作为找矿矿物或成因矿物的研究日趋增多.研究资料表明,一定类型的云母在很大程度上能反映一定的矿化组合或矿床类型,换言之,不同岩石类型以及由此产生的矿床、赋予其云母类矿物一定的标型.因此,研究云母类矿物,对于指示矿化或地质体的成因有重要意义.大厂锡、锌等多金属矿田的形成与龙箱盖黑云母花岗岩有密切关系,本文试图对其黑云母的标型特征及其地质意义进行初步讨论.
Since the 1960s, there has been an increasing number of studies on the mica minerals as prospecting minerals or genetic minerals, and research data indicate that certain types of micas can largely reflect certain mineralization combinations or types of deposits, in other words, different Rock types and the resulting deposits, given a certain type of mica-type minerals.Therefore, the study of mica minerals, indicating the origin of mineralization or geological body is of great significance.Dae tin, zinc and other polymetallic ore field It is closely related to the formation of mica mica in Longjianbai. This paper tries to discuss the typomorphic characteristics of biotite and its geological significance.
