On the basis of geochemical information by REE geochemical characteristics, the depositional environment of the metamorphic protolith, the changing law of REE in metallomorphic stage and migrating law of the metamorphic material as well as metamorphic setting are studied in this paper.
本文主要从稀土元素的地球化学特征所反映的地球化学信息 ,研究变质岩原岩的沉积环境 ,变质阶段稀土元素的变化规律 ,成矿物质的迁移规律 ,变质环境等。
The original rock of Laolingou garnet deposit is a siltpelite and rich in iron The garnet deposit was formed by a series of metamorphic reactions, which has been undergone low to high amphibolite facies P,T condition.
老林沟石榴石矿的原岩为富铁粉砂质泥岩 ,经区域动力热流变质作用 ,在低角闪岩相至高角闪岩相的P、T 条件下 ,通过一系列变质反应形成。
According to the rock body structure, attitude, rock type, chemical component, micro characteristic, and the ore body attitude, the spatial relationship of the ore body and all kinds of rocks, lithology, etc, it can be concluded that ore body is oval column lean to east-north, and the original rock is the gabbro.
通过对含矿岩体结构、产状、岩石类型、化学成分、微观特征,矿体产状、矿体与各类岩石的空间关系,矿石岩性观察研究,认为含矿岩体空间形态为向北东倾的椭圆柱形,原岩为辉长岩、成岩过程中物质成分发生了充分的分异富集,分异作用主要是重力分异、次为结晶分异;成岩后又经历了“角闪岩相→榴闪岩相→绿片岩相”的变质过程,三次变质作用均有金红石形成、第二次是主要成矿作用。
Way of stress reliving was adopted in primary rock stresses testing and calculating in the level with the depth of -408,-500 and -600 meters in Qidong coal mine.
采用应力解除法在祁东矿 - 4 0 8、- 5 0 0和 - 6 0 0三个水平进行了原岩应力测试及计算 ,确定了祁东井田主应力的大小和方向以及三个主应力随深度的变化关系 :祁东煤矿的地应力场以水平构造应力为主 ,最大主应力方向为北东向到近于东西向 ;中间主应力为垂直应力 ,垂直应力接近于上覆岩层的重量 ;最大主应力梯度值为 0 。

Their original rocks are volcanic rocks, epicontinental clastic sedimentary rocks, and ophiolite of volcanic and island arc tholeiitic series or calcium alkali series.
其原岩岩石类型有火山岩，陆缘碎屑沉积岩，火山、岛弧拉斑系列或钙碱系列火山岩、蛇绿岩等。
I think the foliation is resulted from deformation. The original composition of the foliated rock is granite.
我认为岩石中的这些片理是由于岩石变形造成的，片理化岩石的原岩就是花岗岩。
The rock series could be subpided into Weijiagou rock group and Kaiyuan rock group (including Shenjiapuzi rock formation, Zhaobeishan rock formation and Banshigou rock formation).
可划分为魏家沟岩群和开原岩群（包括沈家堡子岩组、照北山岩组、板石沟岩组）。
