Systematic stratigraphical--geochemical studies indicate that the Middle Cambrianand the Qiziqiao Formation of the Middle Devonian which is the ore-localizedstrata of stratabound Pb--Zn deposits in the Dashengshan area, central Hunan, arecharacterized by high contents of ore-forming elements and a full range of associ-ated elements, thus possessing the prerequisites for source-beds.

Systematic stratigraphical--geochemical studies indicate that the Middle Cambrianand the Qiziqiao Formation of the Middle Devonian which is the ore-localizedstrata of stratabound Pb--Zn deposits in the Dashengshan area, central Hunan, arecharacterized by high contents of ore-forming elements and a full range of associ-ated elements, thus possessing the prerequisites for source-beds. A metallogenicsimulation experiment was performed to study the main factors controlling theactivation and migration of the oro-forming elements in these strata. A comparisonof the actual metallogenic physico-chemical conditions in this area with the resultsof the simulation experiment indicates that there are the possibilities of activationand migration of the ore-forming elements from the strata. The geological, traceele-ment, isotopic, structural and geochemical studies have been made to obtain thesufficient evidence of these strata forming the source-beds. As a result, some evi-dence has been found that the ore-forming elements in these strata migrated towardsand were concentrated in the ore-locatized portions. Therefore the Middle Cambrianand the Qiziqiao Formation of the Middle Devonian can be considered as the mainsource-beds of the stratabound Pb-Zn deposits in this area.

系统的地层地球化学资料表明,湘中大乘山区寒武系中统和泥盆系中统棋梓桥组是成矿元素和伴生元素含量较高的层位。在此基础上,除了利用成矿模拟实验证实了在成矿过程中,该区成矿元素有从这些地层中活化迁移出来的可能性外,文中还应用了微量元素,稳定同位素和构造地球化学等方法。找到了成矿元素在这些地层中曾发生过向赋矿部位运移富集的一些直接证据。据此,可以初步认为这两套地层是该区层控铅-锌矿床的主要矿源层。

The translation of Tancheng-Lujiang Fault Zone is argued in recent years,and on which many scholars call in questions in many ways.On the research of the geochemical characters in the later Pro- terozic stratum of southern Liaoning and northern Jiangsu and Anhui,the auther found that the geological characters of the area were quite different,and they were not the product of the same sedimental basin.So there is no great translation existing from geochemistry.

The translation of Tancheng-Lujiang Fault Zone is argued in recent years,and on which many scholars call in questions in many ways.On the research of the geochemical characters in the later Pro- terozic stratum of southern Liaoning and northern Jiangsu and Anhui,the auther found that the geological characters of the area were quite different,and they were not the product of the same sedimental basin.So there is no great translation existing from geochemistry. On the regional tectonic and geody- namics,in the later Proterozic Era,the pattern of the crustal wavy mosaic struture in the east of the North China block played a controlling role in the distribution and evolution of the denudating and sedimental areas.The Geochemical difference between the upper Proterozic Erathem in southern Liaoning and northern Jiangsu and Anhui is the material expression of tectonic difference macroscopicly.

郯城—庐江断裂带平移是近年讨论较多的一个问题。作者在研究了苏皖北部和辽南晚元古代地层地球化学特征之后,发现两地区地球化学特征存在着明显的差异,它们不属于同一沉积盆地。因此,从地球化学角度看,郯庐断裂带不存在巨大平移。从区域构造和地球动力学考虑,晚元古代时期,华北地块东部的地壳波浪状锒嵌构造格局对剥蚀区与沉积区的展布及演化起着明显的控制作用。苏皖北部与辽南上元古界之间的地球化学差异性,在宏观上是构造差异性的物质表现。

Geochemical characteristics of the Upper Archean-Lower Proterozoic Jiaodong Group-the host rocks of the famous Jiaodong gold deposit are presented in this paper. It is shown that the Jiaodong Group is an important Au-bearing formation containing 19.5 ppb Au on average, about 5 times as much as its abundance in the crust. It is also found that the distri-bution of gold in the strata is uneven and that plagio-hornblendite is the prospective Au-bearing rock. In the processes of regional metamorphism, migmatization...

Geochemical characteristics of the Upper Archean-Lower Proterozoic Jiaodong Group-the host rocks of the famous Jiaodong gold deposit are presented in this paper. It is shown that the Jiaodong Group is an important Au-bearing formation containing 19.5 ppb Au on average, about 5 times as much as its abundance in the crust. It is also found that the distri-bution of gold in the strata is uneven and that plagio-hornblendite is the prospective Au-bearing rock. In the processes of regional metamorphism, migmatization and fault-remelting gold in the source bed was remobilized and concentrated to form various types of gold de-posits in this area.
