| 摘 要： | 在综合分析沽源—围场地区成矿地质条件和成矿规律的基础上,利用多源信息量法进行了综合信息成矿预测,圈定出Ⅰ级远景区1片、Ⅱ级远景区3片、Ⅲ级远景区5片。对Ⅰ级预测靶区的成矿地质条件进行了综合分析和评价,并在2个预测矿靶区进行了异常查证,落实了1个铀钼多金属矿床和2个银多金属矿床,证明了综合信息成矿预测在本地区是一种十分有效的成矿预测方法。

| Abstract: | Based on comprehensive analysis of ore-forming geological conditions and ore-forming regularity in Guyuan-Weichang area,and after comprehensive information metallogenic prognosis is conducted by multi-source information content method,a block of grade I prospective area,three blocks of grade II prospective area and five blocks of grade III prospective area are blocked out.The ore-forming geological conditions of grade I prognosis target area are analyzed and evaluated comprehensively,and anomalies in 2 blocks of prog-nosis target area are examined.In conclusion,a U-Mo polymetallic deposit and two Ag polymetallic deposits are verified,and it is proved that comprehensive information metallogenic prognosis is a perfectly effective metallogenic prognosis method in this area. |
