东天山沙垄一带钨矿成矿规律及找矿模型研究

论文选取沙垄一带钨矿床为研究对象,以区域构造演化、区域地质背景、岩浆岩侵入时代研究为基础,较系统的总结了沙垄一带钨矿的成矿规律,指出了沙东一带钨矿主成矿时间为晚三叠世,认为印支期末期为该区成矿作用的高峰;通过对沙东一带钨矿床空间分布规律的研究,总结出沙东一带钨矿床在空间上主要表现为矿点集中成群出现的丛聚性分布、沿区域深断裂的北东东向带状分布、矿群大致以80 km的等距性分布等特征。通过对沙东一带钨矿找矿标志、找矿模型要素、矿床成因的分析研究,建立了沙东一带钨矿区域综合找矿模型。

Study on metallogenic regularity and prospecting model of tungsten deposits in shalong area of East Tianshan

This paper selects the tungsten deposits in Shalong area as the research object, based on the basic research of tectonic evolution and regional geological background, magma intrusive time, and systematically summarized the metallogenic regularity of tungsten deposit in Shalong. Sum This assay stated that the metallogenic time of Shadong tungsten deposit is late Triassic, and revealed that the late Indosinian is the peak of ore-forming processes.From the research on spatial distribution of tungsten deposits in Shadong, the paper, Summed up that the mineralized occurrences distributed as 80m isometric distribution along NEE regional deep faults..Based on the study on prospecting indicators, model elements and the genesis of Shadong deposits, this assay set up the regional comprehensive exploration model of Shadong deposits.
