在我国某地花岗岩的外部接触带中,发现了一个规模巨大的水晶矿床。该矿床以不规则的石英-方解石脉和含水晶的矽嘎岩洞(含晶矽嘎岩洞),生于花岗岩外国的黄绿色矽嘎岩带中。以矽嘎岩为围岩,且与之有生因关系的水晶临床,在世界上还是第一多发现,它与海南岛某地大部以花岗岩为围岩的水晶矿床有显著的不同。我们把这种水晶矿床命名为矽嘎岩型水晶矿。本文想就该矿的成因、普查找矿方向、评价原则等问题加以探讨。
In the outer contact zone of granite in a certain place in our country, a huge crystal deposit has been found. The deposit is based on irregular quartz-calcite veins and crystal-containing igasia caves (including crystalline igala caves) that were born in the yellow-green igneous belt of granite. It is the first discovery in the world that the crystal clinics that take the Si-Ga rock as the surrounding rock and have a genetic relationship with it have significant differences from the crystal deposits that mostly contain granite in a certain place in Hainan Island. We named this crystal deposit a “silicon” rock crystal. This article would like to discuss the causes of the mine, census prospecting direction, evaluation principles and other issues to be discussed.
