Abstract：In order to find out the metallogenic law and metallogenic background of copper-nickel deposit in Early Paleozoic and gold deposit in Early Mesozoic in East Kunlun area of Xinjiang Province, the authors of this paper have carried out four 1:50 000 mineral geological survey sheets (Hongtulin Temple sheet and others) in Aquedun area of Ruoqiang County in Xinjiang Province, using the the working technical method of Prospecting discovery - Law summary - New area discovery. The new progress and main achievements are as follows: ① The basic-ultrabasic intrusions, exposed in Tuteka-Hongtulin region with the same characteristics of magnesium-iron and super magnesium-iron rock, were the product under the combination of depleted mantle and lithosphere mantle in an early cracking environment of Early Devonian period, rather than the ophiolite fragments. ② The pomegranate amphibolite was firstly found in Baishahe Formation of Jinshuikou Group, which was lenticular in gneiss. The two groups of the metamorphic ages in this research were closed to the high pressure metamorphic age (450~430 Ma) and retrogressive metamorphism age (420~405 Ma) in previous research from eclogite and pomegranate amphibolite in East Kunlun, which indicating that there was a large high pressure metamorphic belt (greater than 1 000 km) in Early Paleozoic in East Kunlun. It was of important significance to discussing the tectonic evolution of East Kunlun orogenic belt in Palaeozoic. ③ Through the comprehensive verification of 1:50 000 geochemical anomalies, the authors have discovered six new gold and copper-nickel mineral occurrences, especially the most potential prospecting occurrences of Yugusayi copper-nickel mineralization deposit and Baozigou gold mineralization deposit. ④ On the basis of the systematic summary of ore-bearing horizon, ore-forming geological background, ore-forming times and ore-forming laws in the study area, 2 ore-forming prospect areas are divided and 2 ore-prospecting target areas are delineated. Besides, the potential of dominant mineral resources is preliminarily analyzed.
