本文论述的是在我国首先发现的一个新的水晶矿床类型——产于碳酸盐岩层中的含晶方解石脉型水晶矿床。该矿床的发现,突破了水晶矿床形成的传统理论和地质前提。证明了在无火成岩分布区,在极端贫于二氧化硅的岩层中,在非石英脉体内,不但可能而且已经形成了规模巨大、质量特优的压电水晶矿床。文中对含晶方解石脉(矿体)的产出特征、晶洞的分布以及成矿作用作了叙述。含晶方解石脉的形成与火成岩无关。成矿溶液不是岩浆期后溶液,系由深层地下水通过周流围岩并对围岩成分充分溶解而成的。成晶是成方解石的继续,是同一溶液充填于裂隙空洞中经分异作用而在最后残余溶液中结晶的。成矿是一次持续的作用而非脉冲式的补给。本类矿床属侧分泌成因。
This article discusses a new type of crystal deposit that was first discovered in our country - a crystallized calcite vein type crystal deposit in a carbonate layer. The discovery of the deposit has broken through the traditional theories and geological conditions for the formation of crystal deposits. It is proved that in the non-igneous distribution area, it is not only possible but also possible to form a piezoelectric crystal deposit of great scale and excellent quality in the rock formation which is extremely poor in silica. In this paper, the output characteristics of crystallized calcite veins (orebodies), the distribution of crystal caves and metallogeny are described. The formation of crystallized calcite veins has nothing to do with igneous rocks. The ore-forming solution is not a solution after the magma period, but is formed by deep groundwater flowing through the surrounding rock and fully dissolving the surrounding rock components. Crystallization is the continuation of calcite, is the same solution filled in the fissure cavity in the final solution of residual crystallization by differentiation. Mineralization is a continuous effect rather than a pulsed recharge. This type of deposit is a cause of lateral secretion.
