| Abstract: | The Yangla copper deposit and Luchun Cu-Pb-Zn deposit are located in the middle section of Jinshajiang metallogenic belt. The Yangla copper deposit, which is a representive copper deposit in the Jinshajiang-Lancangjiang-Nujiang region, hosts an estimated Cu reserve of about 1.2×106 tons. The orebodies are hosted in the melange composed of diverse rocks. The ores were deposited in pre-existing thrust faults in Indosinian period and steeply dipping normal fault in Himalayan period. The directions of the maximum principal stress were E-W and NE-SW in the Yangla deposit. E-W direction was related to the westwards subduction of the Jinshajiang Oceanic plate in Indosinian, NE-SW related to the collision between India plate and Asia plate in Himalayan. The Luchun Cu-Pb-Zn deposit is bordered by the Indosinian thrust fault. |
