Geochemical Characteristics of Indicator Elements and Prospecting Criteria for the Danchi Polymetallic Mineralized Belt of the Dachang Tin Field
Based on the regional data of heavy minerals and secondary dispersion haloes, a subdivision of geochemical anomalies has been made for the Danchi ore belt. Geochemical features of the Dachang ore field and the Changpo cassiterite-sulphide deposit are discussed and a model of vertical zoning in the Changpo deposit is established. The assessment indexes for anomalies of various types of ore deposit and indicators for cassiterite-sulphide ore deposits are presented.
The study of the geochemical features of the ore fields and deposits, in combination with geochemical prospecting, is evaluated for developing mineral resources in new areas.
