山东省潍坊市北部煤炭资源找矿方向及成矿预测

Prospecting and Metallogenic Prediction of Coal Resources in North Part of Weifang City in Shandong Province

摘要:

潍坊市北部煤炭预测区位于中国东部滨海平原地带，为隐蔽区找煤的重要靶区。通过对大量的区域地质矿产资料、钻孔资料、煤质分析资料等进行分析总结，确定了预测区的找矿方向位于昌邑断陷盆地内，含煤岩系主要赋存于孔店组地层中，含煤岩系的沉积中心在昌参一、二井一带；进行了成矿预测并对预测区的煤炭资源量进行了初步评价。

Abstract:

Coal predication area in northern Weifang city locates in eastern coastal plain region in China. It is a hidden important target area of coal resource. In this paper, through analysis and summary on regional geological and mineral resources data, drilling data, and coal quality analysis data, oreprospecting direction in forecast area has been determined in Changyi fault basin, coalbearing rock series mainly occur in Kongdian formation, and the deposition center of coalbearing rock series is in No.1 and No.2 Changsen well belts. Coal resources amount in forecast area has been evaluated primarily.
