摘要: 东风硅灰石矿是普查工作新发现的矿产地,其矿物资源量已达大型规模。文章通过大量的野外第一手资料,总结了东风硅灰石矿基本地质特征,并对硅灰石矿物含量计算方法进行了较深入的探讨,在现有勘查成果的基础上,结合矿体空间产出特征和矿体赋存状态,揭示了大东山岩体接触带硅灰石矿的产出特征和成矿规律,进一步明确了湘南地区硅灰石矿的找矿方向。Abstract: Dongfeng wollastonite deposit of Southern Hunan Province is a newly discovered one, its mineral re-sources has reached a large scale. Through a large number of field data, we summarizes the basic geological char-acteristics of Dongfeng wollastonite deposit, and the computing method of wollastonite mineral content is dis-cussed deeply. On the basis of the existing prospecting results, combined with ore body occurrence and ore body occurrence state, revealing the the wollastonite ore bodies are mainly occurred in contact zone of Dadongshan pluton, which is the most prospecting potential area in Southern Hunan Province.
