根据矿物包裹体的成因,可以分为原生、次生、假次生三种.区分这三类包裹体的原则是:1.原生包裹体一般分布在主矿物的结晶位置上(如晶面、负晶形等),若包裹体被个别矿物颗粒所限制,或其在晶体中无一定的排列次序,也是一个依据. According to the genesis of mineral inclusions, it can be divided into three types: primary, secondary and secondary.This distinction between these three types of inclusions is as follows: 1. The primary inclusions are generally located in the main mineral crystallinity (such as crystal plane, Negative crystal, etc.), if the inclusion body is limited by individual mineral particles, or its crystal in the order of no certain, but also a basis.
