小秦岭文峪金矿床深部地质特征及成矿规律

摘要

Wenyu gold deposit is located in the west of the middle zone of Xiaoqinling metallogenic belt. It is one of the 14 large-medium sized gold deposits in Xiaoqinling metallogenic belt. 6 ore bodies have been selected out in deep part of this deposit. The shape of ore body is relatively simple,and mainly occurred as thin vein in Taihua group in greenstone layers and variable TTG rock series. The ore bodies are controlled by strata, structures and magmatic activities. The thickness of ore bodies is stable,and the useful components distributed uniformly. Accord-ing to field prospecting experiences,metallogenic regularity of the deposit has been analyzed. It will provide a basis for subsequent exploration and research of the deposit.%文峪金矿床位于小秦岭成矿带的中矿带西段，是小秦岭成矿带中14处大—中型金矿床之一。矿床深部共圈定出6个矿体，矿体形态较简单，主要呈薄脉状产出在绿岩地层太华群和侵入其内的变TTG岩系中，受地层、构造和岩浆活动控制明显，厚度稳定，有用组分分布较均匀。根据野外找矿经验，总结分析了矿床成矿规律，为该矿床后续勘查和研究提供了一定的依据。
