epidote n.【礦物】綠簾石。

There are lots of primary structures , such as bed interfaces , lagerklufts and diagonal joints , in the emeishan volcanic , which dislocated to be dislocation interfaces later . especially in those primary structures that were filled with the epidote - quartz vein , the dislocation interfaces are more aptter to grew 錯動帶主要是利用玄武巖中原生層面、層節理和斜節理等原生構造錯動變形而成,尤其是當原生構造中充填有熱液型綠簾石?石英脈時,錯動變形更易于發生。

The microscopical observation proves that the main types of granitoid rocks are granodiorite and quartz monzodiorite , and the enclave is mainly monzodiorite . the rock - forming minerals are mainly k - feldspar , plagioclase , amphiboie , biotite , quartz , magnetite , titanite , apatite , epidote , etc . the zonation of the feldspars is very popular . the dark - colored minerals , such as biotite and titanite , have been highly oxidized 通過對本區花崗巖類樣品進行顯微觀察研究,知其主要的巖石類型為花崗閃長巖、石英二長閃長巖,其中的巖石包體主要為二長閃長巖,其造巖礦物為鉀長石、斜長石、角閃石、黑云母、石英、磁鐵礦、榍石、磷灰石和綠簾石等,長石中環帶現象比較常見,黑云母、榍石等暗色礦物顏色較深,表明其氧化程度較高。

Under the hydrodynamitic condition in the outshelf heavy minerals are enriched to a certain extent . they are of horablede - epidote assemblage and contain some authigene ( pyrite and glauconite ) . the content of stable mineral is small and mineral maturity index ( trzg / hp ) is low 在外陸架水動力的作用下,重礦物有一定富集,重礦物以角閃石?綠簾石礦物組合為特征,含有一定量自生礦物(黃鐵礦和海綠石) ,穩定礦物少,礦物成熟度低。

Epidote may be quite conspicuous . 綠簾石有時相當顯著。
