江苏省锦屏—宿迁地区海州式磷矿成矿预测

江苏省锦屏—宿迁地区磷矿成矿带大部分地区被第四系覆盖，给地质勘查带来困难．为此，我们进行了该区海州式磷矿成矿预测．在研究成矿规律的基础上，用积相关分析和信息量计算法进行了预测，两种方法相互结合，确定了３个Ⅰ级成矿远景区、６个Ⅱ级成矿远景区和３个Ⅲ级成矿场景区．为今后进一步工作提供了一定依据。

METALLOGENIC PROGNOSIS ON HAIZHOU-TYPE PHOSPHORUS MINERALIZATION WITH EXAMPLES FROM JINPING-SUQIAN REGION

Abstract In Jinping-Suqian region in Jiangsu there exists a phosphogenetic belt which is difficult to be explored due to being heavily overburdened. In view of this, metullogenic prognosis was made on a Haizhou-type of phosphorus mineralization possibly taking place in the region by means of rank correlation and information calculation in addition to studies on mineralization regularity. Finally, determined were three first-class POtential phosphogenetic provinces, six second-class and three third--class which will all lay foundation for future further searching for this type of phosphate resources
