Abstract
The deposit is produced in the northern wing of Kalpintag anticline in Kalpin Foreland Basin, and occurs in the upper section of Paleogene Suwiyi Formation, the lithology of the ore-host layer is gray-green medium and fine calcareous sandstone, and the ore body occurs in strati-form-like and stratified form, which is consistent with that of the stratum. Total 4 copper ore bodies have been delineated, at the length of 40-530m, the thickness of 1.00-3.94m, and copper grade at 0.33-0.74%. The ore minerals are malachite, copper blue and chalcocite, the ore texture consists of granular texture, metasomatic relict texture and interstitial texture, and the ore structure consists of sparse disseminated structure, crumby structure and scattered structure. In accordance with the deposit geological characteristics, it was preliminarily judged that the type of deposit genesis belonged to continental sedimentary-layer controlling type sandstone copper deposit. The main ore-controlling factor was Palaeogene calcareous sandstone strata ore-controlling.
