Abstract:
Based on geological mapping and profiling combining with existing study achievements, the authors consider that the mineralization of De'erni Cu(Co)ore deposit should be later than its ultra-basic country rock. The genesis of De'erni ore deposit is mainly submarine exhalation-sedimentation, and it experiences later superimposed hydrothermal mineralization. The metallogenic process is such that in extensional tectonic setting, submarine exhalation-sedimentation occurs, the ophiolite breaks up, exhalative materials emplace in the ultra-basic rock along fault belt and extract large mount of Cobalt element from ultra-basic rock. Then, the ore bodies experience complicated tectonic events.
