line-level: 2" class=MsoNormal>According to the study on the porphyry copper deposits in China-Mongolia border region, the authors try to summarize and study the typical porphyry copper deposits in the Paleoasian metallogenic domain through geochemistry method. It is suggested that: 1) the rocks in the region belonged to the series rocks of calc-alkaline to high-K calc-alkaline and low-aluminum; 2) the rocks show Chondrite-normalized REE patterns are oblique to right side and enriched in LREE, flat HREE distribution patterns with obvious Eu negative anomaly. The result of isotopes indicated that all of them are from mantle partial melting; and 3) the deposits in this region are all formed in island-arc environment, and in the specific period of crustal evolution stage. The formations of the deposits have the characteristics of multi-epoch metallogenic, several sources and multi-tectonic movement. This study can help to hunt the big porphyry copper deposit ore in this region.
