Abstract

Abstract

The Xilekuduke porphyry Cu-Mo deposit is a concealed deposit discovered in the northeastern margin of the Junggar Basin, Xinjiang in recent years.In order to clarify the mineralization characteristics of the deposit, construct a prospecting and exploration model, and guide the exploration in the mining area, this paper focuses on a systematic study on the geological characteristics of the deposit.Using the study of mineralization characteristics, alteration characteristics, geochemistry, geophysics, and distribution of altered minerals, a prospecting and exploration model is established.Through field geological surveys, geochemical and geophysical exploration and research methods, the mineralization of this deposit mainly occurs in the Early Carboniferous granite porphyry granite diorite and contact zone surrounding rocks.The deep granite porphyry provides the sources of mineral and fluid.The fracture structures caused by the northwest and nearly north-south faults and rock emplacement in the mining area are important guiding and hosting structures.The main ore-forming elements in soil have zoning characteristics, and geochemical anomalies, mineralization alteration, high-precision low magnetic anomalies, and induced polarization anomalies can delineate altered mineralization bodies.The elliptical alteration of 1~2 km² delineated on the surface of the mining area is often accompanied by alterations such as limonitization, fine-grained silicification, sericitization, clayification, chloritization, epidotization, and hornfelization, which are important prospecting indicators.The established mineral exploration model has reference significance for the exploration of porphyry copper molybdenum deposits in the eastern Junggar and the porphyry deposits in the Central Asian Orogenic Belt(CAOB).
