THE REMOTE SENSING GEOLOGIC INTERPRETATION AND REGIONAL TECTONIC EVOLUTION AND METALLOGENIC REGULARITY FOR THE GOLD DEPOSITS IN WEST QINLING AREA

本文较为系统地论述了金矿床形成的构造岩相条件，中新生代以来控矿构造格架，区域成矿构造演化、成矿规律和成矿模式，重点探讨了区域构造演化和成矿规律的相关性，认为印支期后燕山期大规模陆内造山构造是导致该构造成矿带发生矿化和成矿的关键因素，说明以构造变动的观点指导该区金矿勘查的重要性，对进一步寻找新的隐伏矿床和成矿预测具有重要意义。

The paper systematically illustrates the tectoniclithofacies condition, metallotectonic framework after Meso-cenozoic era, regional metallotectonic evolution, metallogenic regularity and patter of the gold deposit formation, mainly probes into the correlation between regional tectonic evolution and metallogenic regularity. It consides that the intercontinental orogenic tectonic movement, which had been taken place at Yanshan age of post-indosinian orogeny in great extent way, is the key factor to result in metallization and ore-forming of this metallotectonic belt. The research shows that it is important to guide the exploration of gold deposit with the view of tectonic disturbance in this region, it is a significant role to find the new hidden ore deposit and to make the metellogenic prognosis further.
