摘要
矿物中的包裹体是成岩成矿流体(含气液的流体或硅酸岩熔融体) 在矿物结晶生长过程中,被包裹在矿物或晶格缺陷或穴窝中的、至今尚在主矿物中封存并与主矿物有着相的界限的那部分物质。矿物中的包裹体按物理状态分主要分为以下两类:Ⅰ、流体包裹体,又可根据组成的不同分为七个亚类: Ⅰ A.纯液体包裹体;Ⅰ B.纯气体包裹体;Ⅰ C.液体包裹体;Ⅰ D.气体包裹体;Ⅰ E.含子矿物包裹体;Ⅰ F.含液体CO2包裹体;Ⅰ G.油气包裹体;Ⅱ、熔融包裹体,又可根据相态特征分为三个亚类:ⅡA.非晶质熔融包裹体;Ⅱ B.结晶质熔融包裹体;ⅡC.晶质-流体熔融包裹体。本文从综述的角度对矿物包裹体的定义、分类、研究方法及现状进行了详细的阐述,指出其新的研究方法和应用前景。
Inclusions in minerals are tiny matters which were trapped in the minerals or crystal latices and caves during crystallization of the minerals. They sealed up and have a boundary with the host minerals. Based on compositions, inclusions in minerals can be divided into two types： fluid inclusions （type Ⅰ ） and melt inclusions （ type Ⅱ ）. The former can be subdivided into seven types ： Ⅰ A pure aqueous inclusions ; Ⅰ B pure gaseous inclusions; Ⅰ C aqueous dominant inclusions; Ⅰ D gaseous dominant inclusions; ⅠE daughter minerals-bearing inclusions ; ⅠF CO2-H2O inclusions; ⅠG organic inclusions, the latermay be subdivided into Ⅱ A amorphous melt inclusions; Ⅱ B crystalline melt inclusions; Ⅱ C liquid-melt inclusions. This paper summarizes definition, classification, research methods, future research field and application of the minerals＇inclusion.
