The quartz studied in this paper is produced in six mineralization stales of Qiyugou gold deposits.Each stage has its own mineral paragenetic association showed in table 1.Stage Ⅰ,Ⅱ,stage Ⅲ,Ⅳ,Ⅴ and stage Ⅵ are respectively grouped under vanward,major and late mineralization periods. The systematical thermoluminescence analyses of the quartz in six stages yield a meaningful result:the thermoluminescent curves of the quartz in vanward period show a major peak with a minor one in its left flank;the curves of the...

The quartz studied in this paper is produced in six mineralization stales of Qiyugou gold deposits.Each stage has its own mineral paragenetic association showed in table 1.Stage Ⅰ,Ⅱ,stage Ⅲ,Ⅳ,Ⅴ and stage Ⅵ are respectively grouped under vanward,major and late mineralization periods. The systematical thermoluminescence analyses of the quartz in six stages yield a meaningful result:the thermoluminescent curves of the quartz in vanward period show a major peak with a minor one in its left flank;the curves of the quartz in maior period,possess double peaks; the quartz of late period,however,gives pronounced single peak curves. As per this result,the division of vanward,major and late mineralization periods is proved to be reasonable.This result also makes the division of mineralization periods of other gold deposits of same type (so called ‘Qiyugou Type’)possible.It can be taken as an effective exploration mark for ‘Qiyugou Type’ gold deposits. The correlation of peak I temperature of Qiyugou gold deposits with those of Jiapigou metamorphic hydrothermal gold deposit,Tuanjiegou hypergene magmatic hydrothermal gold deposit and Linglong re—melting magmatic—migmatie hydrothermal gold deposit suggests that the Qiyugou gold deposits are genetically close to Tuanjiegou gold deposit and the gold—bearing fluid responsible for the formation of Qiyugou deposits is hypergene magmatic in nature.Besides,the breccia type and quartz vein type as well as the tectonically fractured zone metasomatite type deposits in Qiyugou area are of same genesis,and belong to a single metallogenic system.

祁雨沟金矿床不同成矿阶段石英的天然热释发光性具有显著的差异。其中前锋成矿期热释光曲线呈“(隐峰)+主峰型”,主体成矿期热释光曲线为“双峰型”,矿化晚期热释光曲线为“单峰型”。据此可对“祁雨沟式”金矿床成矿期(阶段)进行划分,同时判明成矿热液与浅成岩浆热液有关,祁雨沟隐爆角砾岩和石英脉型以及构造破碎带蚀变岩型金矿为同一成矿系列。石英双峰型发光曲线是“祁雨沟式”金矿化的指示标志。

There occur three types of gold deposits in northern Liaoning Archean metamorphic terrain, i. e., gold deposits associated with Archean zinc-copper massive sulfides, Archean metamorphosed gold deposits in synchronous ductile shear zones and phanerozoic magmatic-hydrothermal gold deposits. Galena from gold-bearing zinc-copper massive sulfide ores contain least radiogenic lead, and lead isotopes are distributed on the whole along isochrons. The...

There occur three types of gold deposits in northern Liaoning Archean metamorphic terrain, i. e., gold deposits associated with Archean zinc-copper massive sulfides, Archean metamorphosed gold deposits in synchronous ductile shear zones and phanerozoic magmatic-hydrothermal gold deposits. Galena from gold-bearing zinc-copper massive sulfide ores contain least radiogenic lead, and lead isotopes are distributed on the whole along isochrons. The average stacey's two-stage model age is 2610 Ma, and the mode of occurrence of galena indicates the age of remobilization of sulfides, namely, the age of reenrichment of gold and silver. Pyrite, which crystallized earlier than galena, contains relatively more radiogenic lead and displays much younger model age (681鈥?838 Ma). The insignificant variation in Th/U ratio suggests that radiogenic lead must have been produced as a result of in situ U and Th decay of pyrite.

辽北太古宙变质地体上发育有三类金矿:太古宙锌、铜块状硫化物矿床伴生金矿、太古宙同韧性剪切带变生(质)热液金矿和显生宙岩浆热液金矿。块状硫化物伴生金矿中方铅矿模式年龄平均为2610Ma,其产状反映为活化年龄;其黄铁矿含较多放射性成因铅,存在铅同位素后期增长效应,模式年龄不具计时意义。变生热液金矿中黄铁矿铅同位素组成特点为~(206)Pb变化很大,~(207)Pb变化很小,~(208)Pb也变化很小,结合黄铁矿产状说明存在铅同位素短期生长效应,而铅源自太古宙绿岩。显生宙岩浆热液金矿中铅同位素均不具计时意义,但各自组成等铅域,在铅构造图解上处于地幔-下地壳线附近。本区金矿铅同位素研究说明,尽管铅同位素在大多数情况下不具计时意义,但结合矿床地质研究尚可标定成矿物质来源和成矿环境。

Tasti gold deposit is of an altration type in fracture zones. The study of stable isotopes, inclusions and metallogenic elements as well as physical and chemical conditions reveals that the metallogenic fluid is the mixture of magmatic fluid with water and precipitation. The metallogenic fluid is of high salinity, high density and high volatile. The ions of inclusion have the similar composition with those of magmatic hydrothermal gold deposit. In the early metallogenic stage the ore fluid is in an acid...

Tasti gold deposit is of an altration type in fracture zones. The study of stable isotopes, inclusions and metallogenic elements as well as physical and chemical conditions reveals that the metallogenic fluid is the mixture of magmatic fluid with water and precipitation. The metallogenic fluid is of high salinity, high density and high volatile. The ions of inclusion have the similar composition with those of magmatic hydrothermal gold deposit. In the early metallogenic stage the ore fluid is in an acid oxidization enviroment; in the main metallogenic stage it is in an intermediate reduction enviroment. The gold-bearing fluid moved along the fractured alteration zone, and then concentrated and precipitated to form ore body.

塔斯特金矿床为一破碎带蚀变岩型金矿。通过稳定同位素、包裹体、成矿元素及成矿物理化学条件的研究,提出该矿的成矿溶液是岩浆水和大气降水之混合物。成矿元素主要来自深源侵入的二长花岗岩。成矿温度为中偏高温。成矿溶液为高盐度、高密度和高挥发份条件。为深源岩浆侵入的花岗岩中破碎蚀变岩型金矿。
