摘要
在完成大兴安岭地区1∶5万航空物探测量工作基础上,结合相关地质、化探、遥感、地形等资料,采用"综合筛选"原则对区内的航磁异常进行了筛选,并择优对重点异常开展了综合查证。将区内航磁异常划分为9种类型,并对典型的异常区的地质、物化等资料做了详细分析,初步总结了查证经验,为今后区域基础地质、矿产勘查及找矿等工作提供较明确的地球物理依据。
On the basis of the 1：50 000 airborne geophysical survey work in Great Xing＇an Range, Heilongjiang Province, the authors have filtered aero-magnetic anomalies of the studied areas with the principle of ＂comprehensive filtering＂ and developed a comprehensive verification to key anomalies combined with relevant data of geology, geochemical exploration, remote sensing and terrain. Aero-magnetic anomalies in the studied areas have been divided into 9 types, and the typical anomaly areas were further analyzed in the information of geology, geo- physics, geochemistry and other aspects. The authors have preliminarily summarized the verification experience to provide more definite geophysical gist for the future regional basic geology, mineral exploration, ore-prospecting direction and other relevant works.
