通过系统研究与成矿关系密切的莲花山花岗岩以及钨矿脉、云英岩和旁侧花岗岩的稀土元素地球化学特征,并进行对比分析,探讨粤北石人嶂钨矿床的成矿环境与成矿物质来源。研究表明,面型云英岩与脉侧云英岩以及相关的两类花岗岩的稀土元素组成存在明显差异,具有不同的物质来源,显示两期岩浆侵入与热液活动叠加特点;深部3种花岗岩及其脉侧云英岩的稀土配分模式很相似,表明具有相同的物质与热液来源;隐伏花岗岩体从浅部到深部,稀土总量、δEu值逐渐变小,显示岩浆岩结晶分异程度逐渐增强,为钨矿床形成提供了成矿物质来源;云英岩与花岗岩的稀土配分模式具有一定相似性,都是轻稀土富集,强烈铕亏损,而石英脉大多呈铕富集,相对富集轻稀土;随着成矿时间的推移,成矿环境由还原到相对氧化。因此,石人嶂钨矿床成矿热液与晚期岩浆热液具有相似性和继承性,成矿物质来源除了深部的白云母花岗岩,部分可能来自上部地壳。

By systematically comparing REE geochemical characteristics of granite in Mt.Lianhuashan,tung-sten veins,greisen and side-granite which has close relationship with mineralization,the paper discussed the metallogenic environment and sources of Shirenzhang tungsten deposit in northern Guangdong.It has been shown that REE components of facial-type greisen,vein-side greisen and two types of related granite are obvious different.They have different material sources,which infer to two stages of magmatic intrusion and superim-posed hydrothermal activity.The REE patterns of three types of granite in the deep tungsten vein and its vein-side greisen are very similar,indicating the same substances and hydrothermal sources.ΣREE and δEu of the hidden granite body gradually increase from shallow to deep,showing that the degree of magmatic crystallization differentiation gradually decreased,providing mineral source for the formation of tungsten deposit.REE patterns of greisen and granite

对比研究了枣子沟金矿区内不同类型矿石与成矿有关的岩浆岩及地层的稀土元素地球化学特征，借以示踪成矿物质来源。研究表明，矿床不同类型矿石的稀土元素配分曲线既有相似又有差别，反映成矿物质具有多样性；矿石与容矿岩石（地层、岩浆岩）稀土元素配分曲线颇为相似，总体呈右倾型，具Eu负异常。表明成矿与容矿岩石（地层、岩浆岩）具有一定的成因联系。成矿物质来源于壳源及壳幔混合。地幔流体可能参与了矿床成矿作用。成矿环境表现为早期还原，晚期由还原向氧化转化。

Comparative study on different kinds of ores , metallogenic magmatic rocks and geological features of REE in strata of Zaozigou gold deposit was conducted to trace the source of ore-forming minerals .Research shows that REE curves of different ores in the deposit are similar while distinct meaning complex ore -forming minerals .Ores and host rocks ( strata and magmatic rocks ) curves take on similar forms ,generally the rightwards type and Eu negative a-nomaly .This indicates metallogenesis and host rocks are related .The ore-forming minerals came from crust source and mixture of crust and mantle .Mantle fluids may have participated in the mineralization .The early ore-forming settings are reduction and later transmitted from reduction to oxidation .

近年来在青海省祁漫塔格地区陆续发现了一系列斑岩-矽卡岩矿床，卡尔却卡铜多金属矿床是其中一个典型的矿床。通过对该矿床S、Pb同位素研究，结合前人研究成果与成矿岩石地球化学特征，认为该矿床的成矿物质来源为深源岩浆，同时也有壳源物质的混染，成矿物质具有壳幔混合的特点。

In recent years, a series of porphyry-skarn ore deposits were found in Qimantag area, Qinghai Province in succession, the Karqak copper polymetallic ore is one of typical deposits among them. Through deposit S, Pb isotopic study, combined with previous re?search results and ore-forming rock geochemical characteristics, have considered that the ore-forming material source is from deep magma, also hybridized with crust materials, thus ore-forming materials have characterized by crust and mantle hybrid source.

多才玛超大型铅锌矿床是三江北段铅锌铜银多金属成矿带中的典型矿床，其主要硫化物的δ34 S 值变化范围大，主要集中于－26.72‰～－4.1‰之间，具塔式分布特征；其中，方铅矿的δ34 S 最高值大于黄铁矿的相应值。这表明成矿过程中硫同位素未达到平衡，硫主要是细菌还原硫酸盐的产物。矿区208 Pb ／204 Pb ＝38.985～39.253，206 Pb ／204 Pb ＝18.825～18.918；铅同位素构造环境演化图解和Δβ－Δγ成因分类图解显示铅的来源复杂多样，不仅来自上地壳和造山带，还来自壳幔混合的俯冲带。δ13 CV-PDB ＝1.2‰～6.7‰，而δ18 OV-SMOW ＝16.4‰～23.4‰，碳氧同位素明显来源于海相碳酸盐岩，成矿过程中应伴随有碳酸盐岩的溶解作用。综上，多才玛大型铅锌矿成矿物质来源复杂，碳酸岩围岩和深部物质都有可能提供成矿物质来源，生物作用参与成矿的痕迹明显。

The Duocaima Pb-Zn deposit is located in the northern Sanjiang polymetallic metallogenic belt.The values of δ34 S in main sulfides are significantly variable,mainly ranging in between -26.72 ‰and -4.1 ‰ with a normal distribution.The maximum δ34 S value of galena is larger than the correspond-ing value of pyrite,indicating that the sulfur isotopes are in disequilibrium during the process of minerali-zation and that sulfur is originated mainly from bacterial sulfate reduction.The 208 Pb /204 Pb values vary from 38.985 to 39.253,and 206 Pb /204 Pb from 18.825 to 18.918.Tectonic evolution and Δβ~Δγgenet-ic classification diagrams of lead isotope show that the source of lead is complex and diverse.It is not only originated from the upper crust and orogenic belts,but also from the subducted zone with crust and man-tle mixed.The values of δ13 CV-PDB 1.2 -6.7‰ and 18 OV-SMOW 16.4 -23.4‰ show that the C and O are derived from marine carbonates,accompanied by carbonate diss
