IN the study of hydrothermal deposits sulfur isotopes bear much information about the source of sulfur,{1.-forming temperature, the evolution of {1.-forming fluids and the mechanism of metallogenesis. Todetermine whether sulfur isotopes reach equi{3.brium between fluids and sulfur-bearing minerals precipitated from the former and among the sulfur-bearing minerals is the key to the app{3.cation of sulfur isotopegeochemistry to geological problems. As it has been commonly accepted that sulfur isotopic equi{3.brium could not be reached between sulfate and sulfide below 3.0℃, {3.ttle attention has been paid to thepossible mechanism of sulfur isotope equi{3.brium between sulfate and sulfide below 3.0℃.

STABLE oxygen isotope is not only an effective approach to tracing water-rock interactions, but also canprovide much information about ore-forming temperature and source and evolution of ore fluids in thestudy of hydrothermal deposits. The rare-earth elements (REE) can be used to trace the sources ofore-forming materials and can also, to some extent, indicate the physical and chemical properties of fluids in the geochemical processes. The combination of these two aspects of research can effectivelyprobe into the geochemical behavior and evolution of REE in the process of water-rock interaction duringhydrothermal ore deposition. On the other hand, the essence of REE as tracers in hydrothermal mineralization can be better understood. In this note the Lemachang independent Ag deposit in northeastern Yunnan is selected for a case study.

Based on detailed and systematic researches of the geology of ore {1.s, fluid inclusions and isotope geochemistry etc., and regarding the Late Paleozoic fluid system of the Yuebei Basin as an integrated object in this paper, we have revealed the temporo-spatial evolution law of the basin＇s fluid system and discussed its ore-forming effects by simulating and analyzing the distribution of ore-forming elements, the fluid thermodynamics and dynamics of evolution processes of this basin. The results show that Late Paleozoic ore-forming fluid systems of the Yuebei Basin include four basic types as follows. （1. The sea floor volcanic-exhalation system developed during the rapid basin slip-extension stage in the Mid-Late Devonian, which affected the Dabaoshan region. It thus formed the Dabaoshan-type Cu-Pb-Zn-Fe sea floor volcanic-exhalation sedimentary {1.s. （2） The compaction fluid system developed during the stable spreading and thermal subsidence-compression stage of the basin in the Mid-Late Devonian. The range of its effects extended all over the whole basin. It resulted in filling-metasomatic {1.s, such as the Hongyan-type pyrite {1.s and pyrite sheet within the Fankou-type Cu-Pb-Zn-S {1.s. （3. The hot water circulation system of sea floor developed during the stage of basin uplifting and micro-aulacogen from the late Late Carboniferous to Middle Carboniferous. The range of its effects covered the Fankou region. It thus formed MVT {1.s, such as the main orebody of the Fankou-type Pb-Zn-S {1.s. （4） The gravity fluid system developed during the stage of fold uplifting and the basin closed from Middle Triassic to Jurassic, forming groundwater hydrothermal {1.s, e.g. the veinlet Pb-Zn-calcite orebodies of the Fankou-type Pb-Zn- S {1.s. Migration and concentration of the ore-forming fluids were constrained by the state of temporo-spatial distribution of its fluid potential. Growth faults not only converged the fluids and drove them to m

本文首次报道华南古生代武夷-云开造山带东南缘的兰排镁铁-超镁铁质岩体富钪(Sc)风化壳,初步计算获得区域内钪的潜在资源为524~566 t,为一潜在大型风化壳型钪矿。兰排岩体呈小型岩株侵入到永和闪长质岩体内,主要由橄榄岩、辉石岩和辉长岩组成,辉石岩锆石^(206)Pb/^(23.)U年龄为(428.3.2.0)Ma(MSWD=0.92)。镁铁-超镁铁质岩全岩w(TFe_(2)O_(3.)为1..1.~1..7%,其中辉石岩钪含量为44×1.^(–6)~97×1.^(–6),总体高于橄榄岩(20×1.^(–6)~89×1.^(–6))和辉长岩(28×1.^(–6)~48×1.^(–6))。兰排这类富钪岩石组合与以往认为富钪的碳酸岩-碱性岩体和阿拉斯加型岩体都存在较大差异,可能代表了一种新的钪成矿母岩类型,推测碰撞后陆内伸展诱发富钪地幔源区熔融可能是富钪母岩浆形成的重要机制。镁铁-超镁铁质岩体上部发育完整的风化壳剖面,可分为全风化层和半风化层。全风化层的上部富集铁(氢)氧化物(磁铁矿、赤铁矿、针铁矿),而中下部以高岭石等黏土矿物为主。半风化层除了包含蒙脱石等黏土矿物,还包括铁钛氧化物及辉石等硅酸盐矿物或相关蚀变矿物。风化壳样品的Sc含量为21.1.^(–6)~3.4×1.^(–6),富集程度最高可达相应基岩的3.以上。其中,钪含量最高的样品主要分布在铁氧化物最富集的全风化层上部,其钪含量多数超过1.0×1.^(–6)。风化壳钪含量与红土化指数(IOL)呈明显的正相关性,表明红土化过程对风化壳钪的富集有显著影响。初步研究认为钪在风化壳红土化过程中经历了活化-迁移-沉淀的多阶段富集过程:1.风化早期钪以类质同象替换的形式赋存在蒙脱石等黏土矿物中;2)风化后期磁铁矿和蒙脱石溶解,钪赋存在以铁(氢)氧化物为主的矿物中,并达到最高程度的富集(Sc>1.0×1.^(–6));3.风化晚期铁(氢)氧化物溶解,一部分钪向下迁移到特定层位。兰排镁铁-超镁铁质岩体富钪风化壳的发现弥补了我国高品位风化壳型钪矿床的空白,丰富了成矿母岩的类型,为华南早古生代成矿作用的理论研究和战略性矿产的找矿勘查提供了一个新的方向。

黔西南滥木厂矿床是世界上罕见的汞(大型)-铊(大型)-金(小型)多金属矿床,具有独特的成矿元素分带现象。本文通过系统研究滥木厂矿床金、汞-铊、汞、铊矿石及围岩样品的主量、微量及稀土元素地球化学特征,对比分析不同类型矿化的成矿环境,以探讨成矿元素共生分离机制。研究表明,相对于滥木厂矿床的围岩样品,同岩性的各类矿化岩石的SiO_(2)含量显著增加,CaO和MgO含量之和明显降低,表明成矿过程中伴随广泛的硅化和去碳酸盐化作用,K_(2)O-Al_(2)O_(3.投图表明区内存在显著的高岭石化作用。各类矿石与围岩均显示Au、As、Sb、Hg、T1.轻稀土富集特征,且具有相似的稀土配分模式;但成矿元素分布于不同的特征因子中,并表现出富集程度的差异,表明成矿物质继承了原岩的部分地球化学特征,在成矿过程中发生了分离。Y/Ho比值在金矿石中普遍高于28,在其它矿化类型岩石中均低于28,反映金成矿热液富含氟络合物,汞和铊成矿热液以碳酸氢根的络合物为主。各类矿石通常具有Ce正异常,铊、汞-铊和金矿石普遍显示Eu正异常,汞矿石呈现轻微的Eu负异常,表明成矿环境处于相对氧化的状态,并具氧化还原波动性。综合元素地球化学特征与收集的碳、氢、氧、硫、铅同位素成果,认为滥木厂矿床金、汞、铊矿化的成矿物质及成矿流体具有多源性,各类矿化在温度、氧逸度、酸碱性及配合物类型等方面的差异可能是成矿元素产生分异的重要原因。
