逻辑信息法在华北地块北缘金矿预测中的应用

华北地块北缘金矿资源十分丰富.该文对华北地块北缘的金矿进行了成因分类,共分为3大类7亚类.在综合信息成矿理论的指导下,对岩浆重熔热液型金矿、岩浆同熔热液型金矿床以及火山-次火山热液型金矿床利用逻辑信息法进行了定量预测,总共预测出12个最有远景的区域.对华北地块北缘的金矿找寻具有指导意义.

Metallogenic prognosis of gold deposits by method of logical information on northern border of North China massif

The northern border of North China massif is an important sector of goldfields in China. Three main types and seven subtypes are genetically classified for the gold deposits at the northern margin of North China platform. Under the guidance of synthetic information theory, the authors have quantitatively appraised the three types of gold deposits in the area using the method of logical information, that is, remelted-magmatic hydrothermal, syntecnic magmatic hydrothermal and volcanic-sub-volcanic hydrothermal gold deposits. 12 regions are predicted to be most perspective. This has a realistic guiding significance for searching after gold deposits in the northern border of North China massif.
