GEOLOGICAL CHARACTERISTICS AND METALLOGENIC MODEL OF SUPER-LARGE KOUNRAD PORPHYRY COPPER DEPOSIT,KAZAKHSTAN

Wei Shi

Abstract

The Kounrad porphyry copper deposit was discovered 70 years ago in the Balkhash Metallogenic Belt of the Central Asian Metallogenic Domain,.It is a typical super-large porphyry copper deposit developed under the tectonic environment of continental margin arc,with a metallogenic model of granodiorite.The vertical and lateral zonings of the wall rock alteration and ore mineral assemblages are obviously observed in the deposit.High content ore in the leaching zone and the ore deposition at a very shallow depth made it easy to be mined.It is suggested that the metallogenesis of the deposit was controlled by the circular structure,and had a very close relation with the secondary quartzite and argillic alteration.
