| 摘 要： | 蓟县地区是天津市重要的金属矿产成矿带,分布有钨、金、钼、铜、锰等矿产资源。其中,钨成矿与岩浆活动有着密切关系,成矿岩体主要为印支晚期中酸性岩体,矿床为石英脉型。通过研究典型矿床沿河钨矿,分析了该区钨成矿地质特征,研究了区域成矿规律;利用地质、矿产、物探、化探、遥感等综合信息,建立了区域预测模型;运用综合地质信息法圈定最小预测区2个,采用脉状矿床资源量估算法估算钨矿资源量约50 000t。蓟县地区钨矿仍有一定的找矿前景。

| Abstract: | Jixian area is a main metal ore area in Tianjin including tungsten, gold, molybdenum, copper, magnese and so on. Tungsten is closely related to magmatism. The tungsten ore hosted rock body is dominated by the late Indisinian intermediate-acidic intrusive body and the deposits are dominated by quartz vein type tungsten deposit. The Yanhe tungsten deposit is a typical one and is investigated in its metallogenic characteristics and regional background. Based on data of geology, mineral resources, geophysical survey, geochemical survey and remote sensing geology the regional tungsten ore prediction model is established and two small target areas are predicted with mineral resource estimated at 50000t. Jixian area is potential for further tungsten ore prospecting. |
