含碲金矿床中碲的赋存状态研究是对其进行综合开发利用的技术关键.文章采用高分辨率扫描电镜(SEM)结合X射线能谱(EDS)和元素面分布技术(EDS-Mapping),首次对山东省归来庄金矿田的卓家庄金矿床中金属类微细矿物及蚀变围岩进行元素空间分布及丰度分析,定性确定可能存在的矿物种类、形态特征及各矿物间的空间关系.在此基础上,采用EDS微区成分分析法分别对各含碲矿物进行了精确的成分测定,最终得到矿石中含碲矿物的化学式和空间分布特征.研究结果表明,山东卓家庄金矿床中含碲矿物均以浸染状的他形镶嵌分布于主矿物之间,颗粒大小从几微米到几百微米,总体以二十几微米最多,不同粒级的碲化物常相互伴生;含碲矿物种类有单质碲矿、PbTe、FeTe2、AgAu2Te6和CuxAg1-xAu2Te6,其中后两种矿物为本研究首次发现.

With the oil and gas exploration and development of mineral resources, the challenge to the integrated management over the non- oil mineral tenements overlapping becomes more critical during the operation of oil and gas. This article creates a database of non-oil and gas resources in the area of overlap mining right to provide evidence to the management of overlay zones and decision making, using the secondary development of MAPGIS- related software to spatial analysis, and focusing on treatment technique which is suitable to the requirement of overlapping areas, the area intersects the neighborhood, the line crosses the area and the point of intersection with the neighborhood...etc to establish a way to overlay analysis on tenement blocks and analysis of administrative division, protocol analysis block recovery and analysis of temporary overlay to select the block.
It is known that not only the upper neutral plane in an anticline but also the lower neutral plane in a syncline(the slope part) can be the area favorable to development of reservoir.A further analysis through exploration practice has indicated that the bedding tensional zone developing in the lower neutral plane in a tensional fold,especially in a carbonate anticline(a buried-hill),can be also the area favorable to developing reservoir.Surface and seepage karst belts generally develop in the fan-shaped tensional zone of the upper neutral plane in a carbonate tensional fold,where developing solution pores and holes commonly show the clutter reflection in seismic feature,and seepage and subsurface karst belts generally develop in the bedding tensional zone of the lower neutral plane in the tensional fold,where developing solution pores and fractures commonly show "beads" reflection.It is indicated that in Tarim Basin,palaeokarst that include contemporaneous karst,weathering-crust karst and burial karst develop in carbonate rock,where surface and seepage karst belts develop in the fan-shaped tensional zones and weathering-crust karst and burial karst develop in the bedding tensional zones,all of which are favourable to reservoir development.The contemporaneous karst and burial karst reservoirs generally develop in the fan-shaped zones and the bedding tensional zones of Cambrian and Ordovician carbonate rocks and the Burial karst reservoir commonly develops in the bedding tensional zone of Carboniferous CⅡ-Oil Group carbonate rock.

Build a database for the management of holders at the mining property in the field of oil and gas is a fundamental and important work.On the basis of MAPGIS,this article focuses on explaining the key elements when it comes to build a database,procedures,techniques and updates,considering the evaluation contributed to the rights of mining areas second time developed with the situation of Zhejiang Oilfield,and provides technical assistance for the implementation of a systematic expertise of the right to the mine areas and the registration of rights to mine strategic constituencies.
There are four types of folds in the eastern part of Tarim Basin:(1)the strain folds that commonly develop in the central part of Manjiaer Sag,(2)the cleavage folds that usually are in the slope zones of Manjiaer and Yingjisu sags,(3)the tensional folds that majorly are in Tanan Uplift of Altun Mountain foreland and Tabei Uplift of Tianshan Mountain foreland,(4)the shear crack folds that mainly develop in the forelands of the Altun Mountain and the Tianshan Mountain.Three periods of fold neutral planes are superimposed in the eastern part of Tarim Basin,which formed during the Caledonian-Hercynian,the Indosinian-Yanshanian and the Himalayan periods.The last Himalayan neutral planes are of reconstruction to former paleo-neutral planes so that they play the important roles of controlling hydrocarbon accumulation.Since this region had been a persistently subsiding aulacogen during early Paleozoic era and was a rapidly rising paleouplift during late Paleozoic to Triassic time,we are actually looking for oil and gas in the residual paleouplift.The strata of upper neutral planes are most denuded seriously in the paleouplift area while the residual strata of lower neutral planes are not favorable for hydrocarbon accumulation.The fact that relic oil and gas flows were met in some drills into the lower neutral planes of anticlines prefigures that the structural/lithologic reservoirs along the slope zones in lower neutral planes of adjacent syclines should be the hopefull prospecting locations.It is suggested that the Upper Sinian,the Middle to Lower Cambrian and the Lower Ordovician Penglaiba dolostone,as well as the Silurian and Jurassic clastic rocks are the favorable exploration targets in this rigion.
Based on gravity anomalies,magnetic signatures,seismic dara,drilled wells,and geotectonic property and Cenozoic major tectonic deformation,three basement areas of the Cenozoic basin,i.e. the northern,the western and the southern ones,can be divided in South China Sea. The northern basement is characterized by Paleozoic metamorphic rock and Mesozoic residual faulted depression and it is be further divided into 3 subareas,which include the Beibu Gulf basement subarea,the Pearl River Mouth Paleozoic basement subarea and the Xisha Islands Paleozoic basement subarea. The western one is characterized by strike-slips and it includes 3 sub-zones,i.e. the Yinggehai Paleozoic basement subarea,the Zhongjiannan and the Wanan Mesozoic basement subareas. The southern one is more complex and it is divided to 2 sub-areas,i.e. the Zengmu early Cenozoic folded basement subarea and the Nansha Paleozoic-Mesozoic complex basement subarea. These 8 sub-areas are separated each other from the subduction-collision suture belt,the ophiolite suite belt,the deep-sea radiolarite belt,the mid-ocean ridge basalt belt and the deep great strike-slip fracturing belt. These belts show different evolution histories and dominate several types of geological characteristics of Cenozoic sub-basins in South China Sea.
