| 中文摘要: |
| 红旗排透闪石滑石矿床位于江西于都县,本文在详细的野外地质调查的基础上,研究该矿床地质特征及成因。研究结果表明,该矿床的透闪石资源量达大型规模且滑石资源量达中型规模。滑石、透闪石矿体赋存于岩体外接触带中二叠统小江边组中,矿体呈层状、似层状,具有一定的层控性,主要矿石类型为滑石矿石与透闪石矿石。分析认为小江边组钙镁质泥岩及富硅中酸性岩浆岩是该矿床主要控矿因素,矿床发育透辉石、透闪石、滑石、金云母及蛇纹石等典型的镁矽卡岩矿物,属接触交代镁质矽卡岩型矿床。研究成果可为同类型矿产勘查提供依据。 |
| 英文摘要: |
| The Hongqipai tremolite talc deposit is located in Yudu County of Jiangxi Province,based on detailed field geological survey, this paper studies the geological characteristics and genesis of the deposit.The research results show that the resource of tremolite in the deposit reaches a large scale and the resource of talc reaches a medium scale.Talc and tremolite ore bodies occur in the middle Permian Xiaojiangbian formation in the external contact zone of the rock mass. The ore bodies are layered and stratoid, with a certain degree of strata control. The main ore types are talc ore and tremolite ore.The analysis shows that the calcium magnesium mudstone and silicon rich intermediate acid magmatic rocks of the Xiaojiangbian formation are the main ore controlling factors of the deposit. It is found that the deposit develops typical magnesium skarn minerals such as diopside, tremolite, talc, phlogopite and serpentine, which belongs to the contact metasomatic magnesium skarn type deposit. |
