| Abstract: | The IOCG copper deposit area structure of the HNX mine in the largest region of the Republic of Chile is located in the polymetallic metallogenic belt of the Chilean mountain fold belt, on the Peru-North Chile IOCG metallogenic belt. The fold structure of this metallogenic belt is strongly developed. Rich in a large amount of copper, molybdenum, lead, zinc, manganese, gold, thallium, selenium, tellurium and other minerals, the IOCG copper deposit in the HNX mining area, the largest region of the Republic of Chile, the amount of copper metal detected was about 30,000 t, with an average thickness of 5.74 m and an average grade of 1.20%, it is a typical deposit of the ore belt. Significance. The article systematically describes the geological characteristics of the ore deposit, analyzes the ore-forming geological conditions, and studies the IOCG copper deposit in the ore area from the aspects of the ore-forming laws and ore-searching indicators. Summarizing the ore-forming characteristics and development experience of this deposit is of certain significance for further development of ore prospecting around the mining area. |
