Abstract:

Based on the 1：200 000 geochemical exploration data of northwest of Hebei Province and the application of geochemical blocks theory and method，we systematically analyzed the characteristics of copper geochemical blocks and resources.Then three copper geochemical blocks and three anomalies were delineated.The No.3 copper geochemical block was worth higher degree of research and focused on，which was coupled to verify by combing with the characteristics of remote sensing liner-ring structure and regional remote sensing alteration information abnormal zone.Optimizing prospect of geochemical block，draw a copper mineral metallogenic prospect areas，thus achieve the goal of metallogenic prediction.

Key words: geochemical block, remote sensing exploration, copper deposit, resources evaluation, northwest of Hebei Province
