The Jiuyishan granitic complex， located in the Nanling Range， South China， is composed of five granitic plutons （Xuehuading， Jinjiling， Pangxiemu， Shaziling and Xishan）. Zircon U-Pb dating of four plutons （Jinjiling， Pangxiemu， Shaziling and Xishan） yielded similar ages of approximately 153 Ma， indicating indistinguishable ages within error. Three plutons except the Shaziling pluton， have consistent εNd（t）（-7.8 to -5.8） and εHf（t）（-9.1 to -2.2） values， which are similar to those of the lower crustal granulitic metasedimentary and meta-igneous rocks in South China. Comparing to other three plutons， the Shaziling pluton has consistent εHf（t）（-7.4 to -6.8） and εHf（t）（-7.5 to -4.7） values and shows similar source， but the Shaziling mafic microgranular enclaves （MMEs） show variable εHf（t）（-14.2 to 4.8） values， indicating a remarkable mantle magma injection of the Shaziling pluton. Zircon Ce/Sm-Yb/Gd， whole-rock CaO-P2O5and CaO-TiO2linear trends revealed that from the Xishan to the Shaziling and from the Jinjiling to the Pangxiemu granites， they experienced apatite and titanite fractionation， respectively. Zircon Th， U， Nb， Ta， Hf， Ti， Y， P and rare earth element （REE） contents and whole-rock Sr， Ba and Rb contents also show that the Shazling， Xishan， Jinjiling and Pangxiemu granites followed a discontinuous evolutionary series， but the Pangxiemu granites exhibit highly evolved nature. Four main controlling factors of W-Sn and rare metal mineralization in granitic rocks were discussed， and we found that the mineralization in Jiuyishan granitic complex was mainly controlled by the fractionation degree and crystallization temperature， but were rarely affected by oxygen fugacity and mantle material input. The Pangxiemu granites show particularly higher Rb and Ta contents than the other three plutons， implying that the ore deposits developed in the Jiuyishan complex were directly related to the most evolved Pangxiemu pluton， with the occurrence of Rb and Ta as the most l

对新疆阿舍勒铜矿中的石英进行了二维、三维热释光和光释光的分析,对该铜矿附近的凝灰岩、玛尔卡库里大断裂中的石英脉、金矿和花岗伟晶岩中的石英矿物进行了热释光、光释光的分析与对比。铜矿体中的石英的释光特征与凝灰岩、断裂带石英脉、金矿、花岗伟晶岩中石英存在较大差异。铜矿中石英在170℃有2个发光峰,波长段分别为340nm和405nm左右,而没有如金矿和断裂带石英中存在的与热液成因相关的560—590nm附近的发光峰,也没有如花岗伟晶岩石英中存在的与深成岩浆作用有关的476nm和625nm附近的2个发光峰。结合对样品的稀土元素进行的中子活化分析,证明铜矿的形成与金的流体成矿不同,属于火山成因铜矿床。

通过对我国南方几个典型砂页岩铜矿床中矿石与围岩的天然热释光特征的分析，表明矿石与围岩均不存在低温峰，大多数只有一个高温峰，其峰温为320～42OC，二者的话线特征也基本相似。但是，矿石的热释光强度显著大于围岩，同一矿区矿石的热释光峰值比围岩高2～8倍，并与CU的品位成正相关关系。反映出矿石与围岩具有成因联系．又具有不同的热演化历史，成矿作用主要发生于成岩晚期，与热液流体活动有关，成矿作用对岩石的热释光特征有一定影响。

Geotectonica et Metallogenia 1997年第Z2期21卷 55-59页

作者： tan kaixuan HAO Xincai and DAI Tagen(Changsha Institute of Geotectonics, Academia Sinica, Changsha, 410013, China)(College of Resource, Environment and Civil Engineering, Central-South University of Technology, Changsha, 410083, China)

The distribution of deep fractures in the China continental crustobody shows fractal structure features. The fractal dimension value of fractures is 1. 493 for the whole continent and 0. 827~ 1. 624 for different tectonic regions. The fractal dimension value of fractures in mobile regions (especially diwa regions) which is 1. 236 ~ 1. 624 is obviously larger than that in stable regions: platform regions which is 0. 827~ 1. 074, and the fractal dimension value of fractures in the jointregions of crustobodies is obviously larger than that in inner regions of a crustobody. The fractal dimension value of fractures reflects the complexity of regional tectonic evolution, movement history and the intensity of tectonic activity. Therefore, fractal dimension of fractures is a quantitative parameter representing geotectonic characteristics.

Kupferschiefer type Cu-Ag deposits occur in the Upper Permian Xuanwei Formation in the Leshan-Muchuan region at the southwestern edge of the Sichuan Basin. Evidences from geology, major element, REE and thermolurninescence analyses suggest that these Kupferschiefer type CuAg deposits were formed during diagenesis and the ore-forming fluids were derived frorn the underlying basalt. Fluid dynamic analyses show that the ore-forming fluids migrated in a unicellular convection, fluids migrated through the basalt, leaching Cu and Ag frorn basalt and forming orebearing solutions, up the western basement highs, moved laterally along the Xuanwei Formation toward the basin centers, presumably to sink back down into the basalt, completing a convection cycle which was about 15 km long, 300 m high and subhorizontal. Further analysis and calculation suggest that there are good geological, tectonic and fluid-dynamic conditions to form middle-scale Cu and giant Ag Kupferschiefer type deposits, but superlarge deposits are unlikely to be formed in this region.
