本文主要依据电子探针微区分析结果,讨论矿物的带状构造,进一步说明矿物的非均一性和矿物分带现象的普遍性。认为矿物带状构造可以划分为显型的和隐型的,对称的和不对称的及简单型的、韵律型的与复合型的几种基本类型,强调隐型带状构造的客观存在。讨论了由化学成分的变化,物理性质的差异,矿物的规律连生,包体的规律性排列所形成的原生带状构造,及交代作用或蚀变作用等所形成的次生矿物分带现象。说明矿物带状构造包含着许多矿物成因信息,并可作为矿物标型性来研究。
In this paper, we mainly discuss the banded structure of minerals based on the results of micro-analysis of electron microprobe, further illustrating the universality of mineral heterogeneity and mineral zoning phenomenon. It is considered that the banded structure of minerals can be divided into two basic types: apparent and invisible, symmetrical and asymmetric, simple, prosodic and compound, emphasizing the objective existence of invisible ribbon structure. This paper discusses the secondary banding phenomenon caused by the change of chemical composition, the difference of physical properties, the regular association of minerals and the regular arrangement of inclusions, and the alternation of secondary minerals by metasomatism or alteration . It indicates that the mineral banded structure contains many mineral genetic information and can be studied as mineral type.
