On the basis of the 1�� 50 000 airborne geophysical survey work in Great Xing'an ��ange��Hei- longjiang 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 di- rection and other relevant works��
