据现有资料统计,浙江共有600多个萤石矿床和矿点,它们绝大部分均分布于中生代火山岩和火山碎屑岩系内,仅少数矿点产于古生代地层中,具有明显的建造控矿特点。根据矿床、矿点资料,结合区域构造控矿条件的分析表明,不同时代形成和产于不同岩性地层的所有萤石矿体和矿化,无不明显地受断裂构造所严格控制,而矿床和矿田的空间分布则又受区域构造带的制约,从而呈现出萤石矿体分布的方向性和分带性以及成矿等间距性等规律。本文主要是以区域断裂构造的展布特点来阐述萤石矿产的区域分布规律。
According to the available statistics, there are over 600 fluorite deposits and ore deposits in Zhejiang Province. Most of them are distributed in the Mesozoic volcanic rocks and volcaniclastic rocks. Only a few of the ore deposits occur in the Paleozoic strata, with obvious construction control Mine characteristics. According to the data of ore deposits and ore deposits and the analysis of ore-controlling conditions in the regional tectonics, it is shown that all fluorite ore bodies and mineralizations formed and produced in different lithology strata in different ages are all under the strict control of the fault structure, and the deposit and The spatial distribution of the ore field is constrained by the regional tectonic belts, showing the regularity and zonation of the distribution of the fluorite orebody and the law of the spacing of the ore bodies. This paper mainly expounds the regional distribution of fluorite minerals based on the distribution characteristics of regional fault structures.
