摘要
本文介绍嵩县西岭绢云母矿床的地质特征，并对绢云母矿物特征进行了初步研究。证明成矿母岩为熊耳群酸性熔岩，矿化从断裂韧性剪切开始，又被早、晚期碱性岩浆期后热液的叠加蚀变改造而完成。该矿是地层、构造、侵入岩三位一体联合控制的中低温热液蚀变岩型矿床。
The geological characteristics of sericite deposits in Xiling, Song County have been introduced in this paper, and its mineral features have been first studied. It reveals that the ore forming parent rock is acid lava of Xiong’er Group. The mineralization was finished that it was from the begining of ductile shearing of rupture, and then being transformed by superimposed alteration of early and late alkaline postmagmatic hydrothermal solution. This mineral deposit belongs to lower to moderate temperature hydrothermal alteration rock type controlled jointly by stratum, structure and intrusive rock-“three in one”.
