摘要
In deep-penetrating geochemical international cooperative project, the results obtained by sequential extraction methods for mobile forms with ultra filtration technology of China and six selective leach methods of Canadian labs showed fairly good anomaly over the Spence porphyry copper deposit in Chile. In order to identify the type of anomaly, the authors extracted and tested industrial mineral phase of Cu. The results show that Cu of oxide and sulfide phases has fairly ideal anomaly discrimination over the ore body. It can thus be confirmed that the above-mentioned anomaly is an ore-induced anomaly. The authors believe that, for underlying porphyry copper ore deposits such as Spence, trace phase analytical method technology should be used to look for industrial mineral anomaly after finding element anomaly by deep-penetrating geochemical methods.
