| 摘 要： | 皇城山银矿床是近年勘查评价出的一处中型低温银矿床.矿床赋存于中生代早白垩世火山岩、次火山岩内,矿体产于北东向花岗斑岩脉中,且严格受火山构造控制.矿区普查阶段比较系统地开展了万分之一岩石测量和原生晕找盲矿专题研究.通过对皇城山银矿地球化学特征研究,建立找矿评价标志,进而对矿带未知地段进行分析对比,做出深部远景评价,取得较好的地质找矿效果.

| Abstract: | The middle scale Huangchengshan silver deposit, prospected and appraised in the recent years, is located in Mesozoic lower-Cretaceous volcanic and subvolcanic rock. All ore veins are confined in the granitic porphyritic dikes and strictly controlled by volcanic structures. 1/10,000 rock survey and blind ore prospecting with primary halos were carried out during reconnaissance stage. On the base of studies of geochemical characteristics of the Huangchengshan silver deposit, prospecting and appraisal indictors are constructed, and compared with unknown segments in the ore belt. Prospective appraisal in the depth is worked out with better effect. |
