根据矿物组合特征，汉诺坝玄武岩中的麻粒岩捕掳体可划分为四种类型：长英质麻粒岩、苏长质麻粒岩、二辉二长麻粒岩和二辉麻粒岩，其中以二辉麻粒岩最为常见。麻粒岩捕掳体均具变质重结晶结构以及块状或条带状构造。不同种类的麻粒岩捕掳体在矿物组成和矿物成分上存在明显差别，但各主要矿物之间存在一定的成分相关性。应用Ｗｏｏｄ和Ｂａｎｎｏ二辉石温度计的计算结果表明，含二辉石麻粒岩捕掳体的平衡温度分布于８００°～９５０℃之间，主要集中于９００°±５０℃范围内，具Ｏｐｘ＋Ｃｐｘ＋Ｐｌ矿物组合的二辉麻粒岩捕掳体的形成压力范围约为０．６～１．１ＧＰａ。二辉二长麻粒岩落在相似的温压范围内。麻粒岩捕掳体在９５０℃处的突然消失指示了第三纪时汉诺坝地区岩石学壳幔边界的温度。
According to the characteristics of mineral assemblages, the entrapment of granulite in Hannuoba basalts can be divided into four types: Chang-Ying quality granulite, Su-Long quality granulite, Erhui two granulites and Erhui granule Rocks, of which the two most common pluton. The granulite entrapped bodies have both metamorphic recrystallized structures and massive or banded structures. Different types of granulite entrapment bodies have obvious differences in mineral composition and mineral composition, but there are some compositional correlations among the major minerals. The calculation results of the Wood and Banno-eclogite thermometers show that the equilibrium temperature of the entrapped body of the diopside-bearing granulite lies between 800 ° C and 950 ° C and mainly lies in the range of 900 ° ± 50 ° C with the Opx + Cpx + Pl mineral The combined pressure range of the two-hurst granulite entrapment is about 0.6-1.1 GPa. Erh-hui two plum-granulites fall in a similar temperature and pressure range. The sudden disappearance of the granulite entrapment at 950 ° C indicates the temperature of the petrologic crust and mantle boundary in the Hannuoba area during the Tertiary.
