摘要
The Huaaobaote Pb-Zn-Ag polymetalic deposit, tectonically located at the south segment of the Dahinggan Mountains ore-forming belt of the circum-western Pacific metallogenetic domain, is a buried hydrothermal vein deposit associated with Early Cretaceous tectono-magma activities discovered in recent years. The results show that：1) the ore and halos forming-elements exhibit a clear zonation. Based on their anomalous intensity the transverse element zonation of the ore deposit are established as follows (from high to low): Cd→Pb→Zn→Ag→Sb→ In→Hg→As→Cu→ Sn→W→Mo→Bi；2) the axial zonation of this ore deposits is as follows: Sb→Pb→Cd→Ag→Zn→Hg →Cu→In→As→Bi→Sn→Mo→W；and 3) indexes such as (Sb×Pb×Cd×Ag)D /(As×Sn×Mo×W)D are constructed as a criterion for evaluating the ore potential in depth.
