小秦岭地区(陕西部分)钛矿找矿方向及工作方法

TITANIUM PROSPECTING IN THE AREA OF XIAOQINLING,SHAANXI PROVINCE

小秦岭地区具有寻找变质岩型等钛矿的地质条件,并已发现有多处金红石、钛铁矿线索。研究认为,小秦岭地区中元古界熊耳群及高山河组地层为寻找变质岩型钛矿有利层位,洛南西沟是碱性岩型钛矿成矿有利区;洛南石门—瓦子坪地区、兰田坝塬—洛南洛源地区和洛南白楼—西沟地区等3个钛矿找矿远景区;石门盆地深部存在一个变质喷发岩型钛铁矿床。应运用重砂测量、高精度重力测量、高精度磁法和电法测量等工作方法开展普查,强化深部钻探找矿,将获得可喜的找矿成果。

Prospecting titanium ore in metamorphic rocks is feasible in geology in Xiaoqinling area, in which several occurrences of rutile and ilmenite mineralization have been discovered. Researches in the Xiaoqinling area have indicated that the favorable horizons of titanium ore in metomophosed rocks occur in the Mesoproterozoie Xionger Group and the Gaoshanhe Formation, titanium mineralization in alkaline rocks in the Xigou area of Lounan county, including three potential areas for prospecting titanium ores in Shimen-Waziping area of Luonan county, Bayuan of Lantian county-Luoyuan of Luonan county and Bailou-Xigou of Luonan county, and a titanium deposit in metamorphosed-eruptive rocks at depth in the Shimen Basin. Application of heavy concentrate survey, high precision gravity measurement, and high precision magnetic and electrical survey would acquire satisfied prospecting results for regional reconnaissance and drilling exploration.
