detrital mineral

The ore-bearing rock of the Xiaowenshan detrital mica mineral is a set metamorphic rock that main body rock is muscovite K-feldspar gneiss.

小文山碎云母矿的含矿岩石是一套以白云母钾长片麻岩为主体的变质岩，原岩为富硅高钾、低钙低镁的粘土质砂岩。

Its composition of detrital mineral was felsic mainly from upper crust.

其碎屑母岩应主要源自上地壳，以长英质成分为主。

About 29 thin sections were used to analysis the detrital and authigenic mineral composition and content.

对29个样品进了薄片分析和鉴定，确定了碎屑颗粒和自生矿物的成分和含量。

On the one hand, the flow of the meteoric water in the multiporous media leads to the infiltration and reprecipitation of the detrital mineral and diagenetic mineral;

一方面，大气水在多孔介质中的流动导致碎屑矿物和成岩矿物的淋滤和再沉淀；

The multi-element regression analysis can be used to quantitatively express and predict the controlling effect of detrital mineral combination over the porosity of sandstone reservoir.

通过多元回归分析，可以定量表达和预测矿物组分对储集层孔隙度的影响。
