吉林省上元古界沉积矿产,是指青白口纪及震旦纪(时限5.7—10亿年)形成的沉积矿产。在这一地质时期是我省铁、铜、磷、稀土等矿产的成矿期,如白房子组的菱铁矿;钓鱼台组的赤铁矿、玻璃原料、石英砂;南芬组的磷矿等。从全球范围看,巴西意大柯罗米群的赤铁矿床、赞比亚——札伊尔含铜砂岩型铜——钴矿床、美国茫顿巴斯碳酸盐稀土矿床都是在这一地质时期形成的。因此总结和认识吉林省上元古界沉积矿产的规律,具有一定的实用意义及经济意义。一、吉林省上元古界地层概况 (一)青白口系下统白房子组主要出露在鸭绿江流域的大粟子、白房子苇沙河、白马浪一带的白房子组,以及层
The Upper Proterozoic sedimentary deposits in Jilin Province refer to the sedimentary minerals formed by Qingbaikouji and Sinian (with a time limit of 5.7-10 billion years). In this geologic period, it is the mineralization period of the iron, copper, phosphorus, rare earth and other minerals in our province, such as siderite in the White House Group; hematite, glass raw material, quartz sand in Diaoyutai Group; Wait. Globally, the hematite deposits of the Corozoic Group in Brazil, Zambia-Zaire copper-bearing sandstone-type copper-cobalt deposits, and the Umbertan carbonate rare earth deposits in the United States all formed during this geological period of. Therefore, it is of practical and economic significance to summarize and understand the laws of the sedimentary minerals in the Upper Proterozoic in Jilin Province. I. Overview of the Proterozoic Proterozoic Strata in Jilin Province (1) The Lower Paleozoic Formation of the Qingbaikou Estuary mainly occurs in the White House Group of Daxiazi in the Yalu River basin, the White House Weihe River, and the Baimalang area,
