矿物生长过程(或之后)捕获(或沿裂隙浸入)的成矿流体(或熔体)被圈闭在晶体缺陷、窝穴(或愈合裂隙)中与主矿物有相界的物质称为矿物中包裹体,其中的内含物随物理化学条件变化出现的盐析物(固相)谓之子矿物。子矿物是在相对封闭体系中由流体或熔体直接生长的固相;在流体中生长时有足够的生长空间,子矿物常呈自形晶;在熔体中生长时,首先沿包裹体腔壁析出与主矿物成分相同的子矿物;随后按吉布斯(Gibbs)相律演化(Романцев 1977)。可见,研究子矿物是了解成矿溶液(或熔体)特征的天然样品,流体包裹体中子矿物主要有石盐、钾盐等卤化物,其次有硫化
The ore-forming fluid (or melt) trapped (or infiltrated along the fissure) during (or after) the mineral growth is trapped in the crystal defect, and the material in the pocket (or healing fissure) that has phase boundaries with the host mineral is called the mineral Inclusions, the contents of which with the changes in physico-chemical conditions salinization (solid phase) that is sub-minerals. Sub-minerals are solid phases that grow directly from fluids or melts in a relatively closed system; there is plenty of room for growth when grown in fluids and the sub-minerals are often in the form of self-shaped crystals; when grown in the melt, The same subminerals as the main mineral are precipitated; it is subsequently evolved in the Gibbs phase law (Романцев 1977). It can be seen that the study of sub-minerals is a natural sample for understanding the characteristics of ore-forming solution (or melt). The neutron minerals in fluid inclusions are mainly halides such as rock salt and potassium salt, followed by sulfidation
