山东莱州道刘家滑石矿地质特征及找矿标志

Geological Characteristics and Prospecting Criteria of Daoliujia Talc Deposit in Laizhou City in Shandong Province

摘要:

山东省已知滑石矿床的赋存层位为古元古代粉子山群张格庄组三段，道刘家滑石矿主矿体赋存于巨屯组，矿床规模达到中型，矿床类型属区域变质热液交代型，工业品级达Ⅲ级品，因此对该矿床的成矿地质要素、成矿模式及找矿标志等成矿规律进行研究具有重要的地质意义。本文通过采用新的成矿理论对道刘家滑石矿典型矿床进行梳理归纳，系统总结了9个方面的成矿要素特征和3个找矿标志，并对矿床成因进行了研究分析，对今后寻找该类矿床具有一定的参考意义。

Abstract:

Talc deposit is significantly controlled by geological layers. The known occurrence layers of talc deposits in Shandong province is the third section of Zhanggezhuang formation of Paleoproterozoic Fanzishan group. The main ore bodies of Daoliujia talc deposit is located in Jutun formation. The scale of the deposit has reached a medium-sized level. The deposit belongs to regional metamorphic hydrothermal metasomatic type deposit. Its industrial grade can reach Ⅲ products. It is of great geological significance to study the ore-forming geological elements, ore-forming models, and prospecting indicators of the deposit. In this paper, by using new mineralization theories, the original geological data of Daoliujia talc deposit has been collected and sorted out, 9 aspects of mineralization element characteristics and 3 prospecting indicators have been systematically summarized , and research and analysis on the origin of the deposit have been conducted. It has certain guiding significance for searching for this type of deposit in the future.
