Starting with the research on the geochemical characteristics and guided by diwa, this paper presents an appraisal of contrast to the bear-mineralization of small intrusive masses of granite.The geochemical characteristics of the bodies near two adjacent areas of Chen County have been studied and both of which belong to the small intrusive masses of granite in diwa. The famous ore field of Dongpo is in close relationship with the granite of Qianlishan, the relations between the mineralized characteristic of which and the movement of magma in various periods may be taken as the model of granite in diwa, Hunan. The granite of Wangxianling was not investig- ated in detail before. Compared with Wangxianling, in Qianlishan there is an increment in silicon and alkali and a decrement in the content of Al_2O_3, and the total amount of Fe and Mg and of the basic composition, and the content of mineralized elements is in great abundance, especially Sn, Zn, Pb and Y, etc, W, Bi, As and Be are rich in Wangxianling, and among these elements, the values of B and F are particularly higher. Two intrusive masses of Qianlishan and Wangxianling are not considered as the same mother rock owing to the obvious differences between their geochemical characteristics. Earlier is the body of Wangxianling and also its mineralized characteristic and perspective of mineralization will differ from each other due to the discrepancies caused by the intrusive country rocks, the position of tectonics and the degree of denudation, etc.

本文以地洼学说为指导,从地球化学特征的研究入手,对花岗岩类小侵入体含矿性进行对比评价。 对比研究了郴县两个邻近岩体的地球化学特征,它们都是地洼花岗岩类小侵入体。著名的东坡矿田与千里山岩体有关,其矿化特征与各期次岩浆活动的关系,可作为湖南地洼花岗岩的典型。王仙岭岩体以前研究较差。千里山比王仙岭,硅碱质增加,Al_2O_3、铁镁总量和基性组分减少,矿化元素含量达到高峰,特别是锡、锌、铅、钇等。王仙岭则富钨、铋、砷、铍等,尤以硼、氧丰度为高。由于它们地化特征上的显著性差异,认为不属同一母体。王仙岭岩体较早,再加上侵入的围岩、构造位置及剥蚀程度等不同,其矿化特征和成矿远景也将相异。

This paper reported Cu-descloizite discovered for the first time in China. The methods such as CHA, XRD, DTA and IRS etc., were used to study Cu-descloizite in a deep going way.Cu-descloizite occurred as orange-brown fine crystal cluster with a density (obs) of 6.14. The chemical composition, structure and physical properties are identical with those reported by other authors.The study on its structural transformation under heating was carried out for the first time in this paper.We consider that Cu-descloizite...

This paper reported Cu-descloizite discovered for the first time in China. The methods such as CHA, XRD, DTA and IRS etc., were used to study Cu-descloizite in a deep going way.Cu-descloizite occurred as orange-brown fine crystal cluster with a density (obs) of 6.14. The chemical composition, structure and physical properties are identical with those reported by other authors.The study on its structural transformation under heating was carried out for the first time in this paper.We consider that Cu-descloizite is a secondary mineral and its occurrence is closely related genetically to polymetal sulfide ore deposit.

文中之羟钒锌铅矿系国内首次发现,用化学分析、X射线法、差热、红外光谱等手段进行了研究。 矿物呈黄褐色完美的晶簇,比重6.14,成分、结构及物理性质和国外同类矿物相同。作者重点地研究了它的热相变全过程,进而指出这是一种和多金属硫化矿床有关的次生矿物。

On analysis of space,the vein and stripped ore body forming the zinc-lead deposit is controlled by the same fracture and stratigraphic combination which pre- sent a gradually-changed transitional rela- tion,and the ore formation is similar on the whole.

The zinc-lead deposit in Dongsheng of Liaoning yields in the beltlike mica-bearing marble of Dashiqiao Formation in Liaohe Group,and are mainly composed of vein and stripped sphalerite and galena. On analysis of space,the vein and stripped ore body forming the zinc-lead deposit is controlled by the same fracture and stratigraphic combination which pre- sent a gradually-changed transitional rela- tion,and the ore formation is similar on the whole. On comparison of Ga/In and Co/Ni value,their enriched coefficient,Zn/Cd, Zn/Fe,Sb/Ag and Sb/Bi value in sphale- rite and pyrite of two different ores,the metallogenetic characters of magma and hydrothermal is showed.And the REE aboundence pattern of ore,wall rock near ore and granite also shows that their for- ming substances are from many sources, and the forming temperature is 200- 400℃. The results above show that the zinc -lead deposit of Dongsheng belong to the stratabound epigenetic post-magmatic and mesothermal deposit.

辽宁省东盛锌-铅矿产在元古宙辽河群大石桥组条带状含云母大理岩中,主要由脉状和层纹状的闪锌矿和方铅矿组合成锌-铅矿床。从空间上分析,组成东盛锌—铅矿的脉状矿体和层纹状矿休均受同一断裂构造和同一岩石地层组合控制,两者呈渐变过渡关系,矿石建造基本相似。通过对两种不同矿石的闪锌矿、黄铁矿的Ga/In和Co/Ni值及其富集系数,Zn/Cd值、Zn/Fe值、Sb/As值、Sb/Bi值对比,均显示了岩浆—热液成矿的特点。同时,根据矿石、近矿围岩和花岗岩的稀土配分,表明其成矿物质源于多源,成矿温度在200—400℃之间。上述结果表明,东盛锌-铅矿应属层控后生岩浆期后中温热液矿床。
