至少有三种主要的世界性的橄榄岩-辉长岩杂岩体类型——层状,同心式和阿尔卑斯型——可以根据其地质产状、岩石种类和比例,矿物学、结构、构造、形态。热效应和经济矿床加以区别。然而,要把许许多多的杂岩体归入某一类别往往是很困难的。一则,它们的岩石类型、矿物组合和矿物成分都大致相似。再者,有些层状杂岩体的显著特征有一部分已被后来的变质作用和形变所模糊,以致类似于阿尔卑斯型或同心式杂岩体。另外,许多阿尔卑斯型杂岩体中的高压矿物已部分地或完全地达到再平衡。但是,我们在野外工作中对这三种主要类型的橄榄岩-辉长岩杂岩 At least three major peridotitic-gabbro complex types-stratigraphic, concentric, and alpine-can be identified based on their geological occurrence, rock type and ratio, mineralogy, structure, structure, and morphology . Thermal effects and economic deposits to be distinguished. However, it is often difficult to categorize a large number of complex bodies into one category. For one, their rock types, mineral assemblages and mineral compositions are roughly similar. Furthermore, some of the salient features of some layered complex bodies have been obscured by later metamorphism and deformation, resulting in similarities to alpine or concentric complex bodies. In addition, high-pressure minerals in many Alpine-type complex bodies have been partially or completely rebalanced. However, we work on these three main types of peridotite-gabbro complexes in the field
