Abstract

Abstract

The Sayak ore field is the only area with the occurrence of large-scale skarn-type copper deposit in Balkhash metallogenic belt, Kazakhstan, Central Asia. In this paper the geological characteristics, ore-field structures and metallogenic model of Sayak ore field are described in detail. Sayak ore field is located in the Sayak graben-synclinorium, including several spatially isolated skarn copper deposits, porphyry Cu (Mo) deposits, Cu-Mo veins and a series quartz vein deposits, which consist of a metallogenic series with skarn-type and porphyry deposits as the two end deposits. The deposits in the ore-field are mainly located in the contact zone between the Middle Carboniferous limestones and the Late Carboniferous granitoids, with a special assemblage of skarn-type Cu-Au-Mo mineralizations. The metallogenic time of main copper deposits in Sayak ore-field is in the Middle to Late Hercynian, with the main and secondary metallogenic ages of 335±2 Ma and 308±10Ma, respectively. The ore bodies are mainly located in the saddle-top segments of locally developed anticlines in the graben-synclinorium, strongly controlled by the tectono-magmatism activities. The most relative granitoids with the copper metallogenesis in Sayak ore field are diorite with Cu content up to >1% and granodiorite up to >0.2%. The copper reserve in the Sayak ore field is estimated to be ~575 kt Cu.
