The rich ores of phosphorite occur in the upper bed of Zhongyicun member, Meishucun formation, Cambrian.
云南安宁磷矿区磷矿富矿赋存于寒武系梅树村组中谊村段的上矿层(C1m1-3)中。
A study of regional geological setting and ore-control factors for the Xiasai Ag-Pb-Zn deposit indicates that NW-trending structures act as conduits for ore fluids and orebodies are controlled by a NNw-trending fault system, while ore shoots are confined equidistantly to secondary structures associated with the NNW-trending fault system.
研究结果表明 ,富矿体在NNW向断裂中按一定间距连续出现 ,并在NNW向断裂伴生的次级构造中集中产出。
There develop some ore shoots in the strong kataclastic rocks in the fault zone.
ＮＥ向压扭性断裂是铅锌矿体的控矿及赋矿构造，富矿体产在控矿断裂较宽大且较破碎的部位，受构造透镜体控制；富矿体长轴向ＳＷ侧伏，侧伏角５０°—６０°，长宽比为２∶１，出露标高向ＳＷ次第降低呈斜列之势；稀土元素、微量元素和硫、铅同位素特征显示成矿物质主要来自千里山花岗岩，成矿时代为燕山早期（１５５—１７０Ｍａ），成矿温度１６８—２４４°Ｃ，属岩浆期后中低温热液矿床，是千里山岩体岩浆成矿系列（东坡矿田）的组成部分。
The orebody has three layers, the central part is extra high grade ore, the middle part is rich ore, and the outer part is lean ore.
喀拉通克铜镍矿是新疆最大的铜镍矿,矿体分为三层,核心部分是特富矿,中间层是富矿,最外层是贫矿。
