寿山石成矿地质条件及成因研究的若干问题讨论

Discussion on Several Problems of Metallogenic Geological Condition and Genesis of Shoushan Stone

  • 摘要: 寿山石是中国传统“四大印章石”之一,国内外久负盛名。对寿山石的研究历史悠久,但更多集中在分类及主要品种的矿物学和宝石学研究,有关寿山石成矿地质条件及成因研究相对较薄弱。本文通过梳理讨论了寿山石成矿地质条件与矿床成因方面的主要问题,认为寿山早白垩世火山喷发盆地小溪组第二段酸性火山碎屑岩是成矿的物质基础,提出了北东向构造控盆(寿山盆地)-北西向断裂控岩(火山岩及火山作用)-火山机构控矿(矿床)-火山断裂控体(矿体)-叠加与改造(基底侵入岩及后期断裂)的成矿与控矿模式;讨论建立了寿山矿田次生石英岩型蚀变矿物相及矿物组合分带,划分出5个蚀变矿物相和6个矿物组合分带。这将促进寿山石矿的勘查、潜力评价和找矿预测工作,乃至矿物学方面疑难问题的解释。

     

    Abstract: Shoushan stone is one of the four traditional stamp stones in China. The study for Shoushan stone has a long history, but mostly focuses on the classification and mineralogical and gemmological research for major varieties. And the study for metallogenic geological condition and genesis of Shoushan stone is relatively weak. The main problems of geological conditions and genesis of Shoushan stone are discussed in this paper. It considers that the acidic pyroclastic rocks of the second member of Xiaoxi formation in Shoushan Early Cretaceous volcanic eruption basin are the material basis of ore-forming. And it is proposed that the ore-forming and ore-controlling model is the NE-trending structure controling basin (Shoushan basin), NW-trending fault controling rock (volcanic rocks and volcanism), volcanic mechanism controling ore (deposit) and volcanic fault controling body. Secondary quartzite type altered mineral facies and mineral assemblage zoning in Shoushan orefield are discussed and established, which can be divided into five altered mineral facies and six mineral assemblage zoning. The discussions will promote the exploration, potential evaluation and prospecting prediction of Shoushan stone deposit, and even the interpretation of difficult problems in mineralogy.
