Abstract
Located on the west coast of the Pacific Ocean, Jiaodong gold concentration area is one of the world's famous gold deposit areas. Its unique metallogenic environment and metallogenic background are favored by geologists of all countries, multi-level and multi-disciplinary scientific research work has been carried out in this area, and good results have been achieved. Linglong gold deposit, located 20 km northeast of Zhaoyuan, Shandong, is a quartz vein type gold deposit. Its veins are controlled by Linglong and Batouqing fault, and vein groups are developed in the area, there are 36, 48, 47, 53, 55, 108 and vein groups 175, among which vein group 175 is one of the main large vein group in Linglong Gold Mine. With the continuous exploitation and utilization of the shallow resources in Linglong Gold Mine, the amount of gold resources kept in Linglong Gold Mine has decreased sharply, and the enterprises are facing the situation of serious shortage of resources. In order to prolong the service life of mines, it is urgent to enlarge the geological reserves of gold deposits and to increase the prospecting and prospecting efforts in deep areas. In this paper are sunnarized the geological and metallogenic backgroud and geologcal characteristics of the ore vein groups 175 and ore-control factor, occurrence pattern of ore body and ore types are analyzed and metalogenic pattern described. Based on prospecting works in which ore is encountered gold ore reserve 192.44×104t (332+333) and gold metal reserve 8.5t are predicted by geologic block method bellow -800m level beteen line 11-101.
Highlights
The Linglong gold mining area is located 20 km north of Zhaoyuan, Shandong province, Its geographical coordinates: E120°27′08′′-E120°33′55′′, N37°26′ 07′′-N37°29′21′′ (1)
Linglong gold deposit belongs to Quartz Vein type gold deposit
Vein Group is developed in the gold deposit area
Summary
The Linglong gold mining area is located 20 km north of Zhaoyuan, Shandong province, Its geographical coordinates: E120°27′08′′-E120°33′55′′, N37°26′ 07′′-N37°29′21′′ (1). Ore vein group 175 is one of the main large vein group in Linglong gold deposit. The total amount of drilling work was 22482.6 m, the amount of tunnel work was 5894.06m, and the Exploration Fund was 31598.8 million yuan; In this paper, the systematic drilling engineering control is carried out for the 175th VEIN group drilling project under the elevation-400m, the gold resources reserves are estimated by using the geological block method, and the amount of (333) gold ore is 428.06 ~ 104t, and the amount of metal is 24.8t. Gold Field in Jiaodong Area, Shandong Province (below-400m elevation) are deeply analyzed, and the vertical zoning regularity of gold mineralization in the deep part of Vein Group 175 is summarized, the deep metallogenic prognosis of the 11-101 exploration line of vein group 175 below -800m level is attempted
