研究了华北地台北缘地质演化、构造分区 ,从南到北依次为乌拉山 -色尔腾山 -大青山陆内隆起区、东升庙 -渣尔泰山陆内裂陷区、狼山 -石哈河陆缘隆起区、霍各乞 -白云鄂博陆缘裂陷区、白乃庙 -白银都西隆起裂陷带、温都尔庙 -爱力格庙裂陷带、苏左旗 -锡林浩特槽内隆起区 .分析了陆缘基底建造和裂谷沉积建造 ,划分出裂谷裂陷期和沉降期沉积 .研究了成矿系统 ,以成矿物质来源的同一性和继承性划分出 3个成矿系统 :(1)变质岩金矿成矿系统 ,以绿岩建造为物源基础 ,有多种矿床类型组合 ,主要产于古陆隆起带的变质岩区 .(2 )海相火山细碧岩及喷流沉积成矿系统 ,主要产于裂谷裂陷期形成的火山岩建造中 ,与火山活动岩浆同期的热水喷流有关 ,有铜、铅、锌多金属矿床 .(3)碱性 -碳酸岩及喷流叠生成矿系统 ,产于白云鄂博裂谷早期碱性 -碳酸岩火山岩中 ,其中伴随高温硅钾热水喷流沉积 ,形成稀有 -稀土 -铁叠生矿床 .主、东矿床新生代以来经受了强烈风化剥蚀 ,并有冲积富集现象 .
Studied the geological evolution and tectonic zonation in the northern margin of North China. From the north to the north, the Wulashan-Serteng-Daqing uplift, the Dongshengmiao- Hekugichu-Baiyunebo marginal rifting area, the White Nailian-Baiyindu uplift rift zone, the Wutuermiao-Ailigemiao rift zone, the Soviet left Zuqi-Xilinhot tank Uplift zone, the construction of continental margin basement and rift sediments were analyzed, and the rift rift and subsidence sediments were divided.The metallogenic system was studied, and the three metallogenic formations were divided according to the identities and inheritance of ore-forming material sources System: (1) Metamorphic rock gold mineralization system, built with greenstone as the provenance base, has a combination of various deposit types and is mainly produced in the metamorphic rock area of the Furukawa uplift zone. (2) And jet flow sedimentary mineralization system, which are mainly produced in the volcanic rocks formed during the rift rifting period and are related to the hot water jet of volcanic active magma and have copper, lead and zinc polymetallic deposits. (3) Alkaline- Carbonate rocks and jet-flow overlying ore-forming systems were produced in early alkaline-carbonate volcanic rocks in the Bayan Obo rift With the deposition of rare earth-rare earth-iron stratigraphic deposits by high-temperature silicalite hot-water jet deposition.The main and eastern deposits have undergone strong weathering and denudation since the Cenozoic and have the phenomenon of enrichment by alluvium.
