    • 摘要: 非洲大陆为全球第二大古陆块,拥有常规铀资源量超400万t.依据活化构造理论,以铀成矿大地构造单元为基础,引入成矿区铀矿床数量和铀资源量的量化标准,对非洲大陆铀成矿进行三级大地构造区划,从小至大分为10个铀成矿区,3个铀成矿省,统归为非洲—阿拉伯铀成矿域.非洲大陆大地构造和铀成矿演化极为复杂,分别按陆核、先期地槽、先期地台、地槽、地台和活化等6个大地构造阶段,进行铀成矿分析.陆核阶段未能形成铀矿床,更未形成铀成矿区,共列出6种不同铀成矿大地构造模式.

    • 摘要: 以四川盆地西南缘之滇东北地区地质演化特征为基础,通过综合分析研究区构造性质、活动范围、演化历史、持续强度及与之对应的物质基础、有机质热演化史等因素,选定研究区页岩气有利勘查区为木杆向斜盆地东南侧至东南部的斑竹林向斜区域.通过钻井验证测试,选区优质页岩厚度较大(厚60~80m)且连续稳定、发育及保存良好、有机质含量高(TOC 0.90%~4.43%,平均2.04%)、成熟度适中(Tmax在400~600°C,最高571.60°C,Ro>2.0%),脆性矿物含量较高且黏土矿物含量较低,孔隙度、含气性测试优良,显示研究区较好的页岩气勘探潜力.综合研究认为地质构造演化对有机质页岩气成藏具重要影响.

    • 摘要: The Early Paleozoic tectonic stage of the North China Craton (NCC) began around 520 Ma,when Gondwana assembled in its peak tectonism.The Middle Cambrian deposition occurred on older strata or basement rocks along margins of the NCC.Then the marine environment expansion and its extensive invasion led to the late Middle Cambrian marine deposition,with the Mantou Formation and afterward strata distributed throughout the NCC.New research results of the Bainaimiao arc belt to the north of northern NCC indicate that the arc was active from 520 Ma and lasted until 420 Ma,which could extend to east Siping in Northeast China.Along the southern edge of the NCC the northward subduction of the Shangdan Ocean took place during ca.514-420 Ma.Marine regression occurred later than the Majiagou phase in Middle Ordovician in most parts of the NCC.Recently some Devonian plutons and volcanic rocks were recognized in northern NCC.The Late Carboniferous sedimentary sequence with the'G'layer of bauxites at its bottom overlies the Middle Ordovician limestone in unconformity.The bauxites were derived mainly from ashes produced by volcanism mainly in the Inner Mongolia Paleo-uplift during Paleozoic period,particularly in latest Early Carboniferous to Early Permian when the northern margin of the NCC evolved as an Andean-style active continental margin.The sequence is mainly elastic formations composed of coal-bearing sandstones and siltstones interlayered with marine limestone and volcanic ash,which demonstrates that they formed in a terrestrial-marine transitional or terrestrial environment with volcanic arc settings.After late Early Permian a terrestrial environment was dominant in the NCC.In southern NCC and the Qinling Orogenic Belt spreading of the Mianlue Ocean between the South China Craton and the South Qinling Block was sustained in Late Paleozoic,and the northward subduction-accretion of the Mianlue Ocean was active in Late Paleozoic.In Triassic the collision between the South China Craton and the South Qinling Block along the Mianlue suture resulted in intense shortening and uplift of Qinling Orogenic Belt and HP/UHP metamorphism documented in Hong'an-Dabie-Sulu terranes.Meanwhile in northern NCC significant changes in tectonic deformation and magmatism occurred in Late Triassic.In the Panshan region,Xiabancheng region and Niuyingzhi region of northern NCC,intense regional folding and thrusting took place around 210 Ma or slightly later,suggesting that the NCC entered into its initial decratonization stage.%华北克拉通古生代的大地构造演化始于大约520Ma,此时冈瓦纳古陆的聚合正处于峰期.中寒武世华北克拉通古生代最早的沉积记录始于其边缘的更老地层或者变质基底之上.随后,海相环境扩展,广泛的海侵导致中寒武世晚期馒头组及其上的地层广泛分布于华北克拉通.华北克拉通北部以北的白乃庙岛弧带新的研究结果显示这一岛弧始于520Ma,并延续到420Ma,其可以向东延伸到我国东北的四平以东.沿着华北克拉通南部边缘,商丹洋在514~420Ma期间发生向北的俯冲.华北克拉通的大部分地区在中奥陶世马家沟期发生海退.近10年来在华北克拉通北缘识别出一个又一个泥盆纪深成岩体和火山岩.石炭纪晚期开始的新的沉积层序以“G层”铝土矿为底,其平行不整合,或假整合在中奥陶世马家沟组灰岩之上.铝土矿很可能是从内蒙古古隆起,一个深位剥蚀的岩浆弧,曾经发育的火山喷发活动形成的广布的火山灰转变而来.这进一步说明晚古生代华北克拉通北缘曾经是一个安第斯型活动大陆边缘.这一沉积序列以碎屑岩为主,下部夹海相灰岩和火山灰层,表明其形成于海陆过渡的火山弧环境.二叠纪早期之后华北克拉通的沉积环境转变为陆相.华南地块与南秦岭地块和华北克拉通之间的勉略洋在晚古生代持续向北俯冲增生,三叠纪晚期发生碰撞,导致大别—苏鲁超高压变质带的形成.与此同时,在华北克拉通北部显著的构造变形和岩浆作用发生在三叠纪晚期.燕山地区盘山等地三叠纪晚期的强烈褶皱、冲断发生在约210Ma,与华北克拉通周缘的强烈构造变形同期.这也暗示华北克拉通此时已经开始失去克拉通的稳定构造性质.

    • 摘要: 粤西-桂东地区是我国重要的矿产资源基地,是研究区域成矿作用和大地构造演化耦合关系的理想地区.本文基于粤西-桂东地区四套主要成矿系统的地质特征的研究,结合区域内矿床精确定年和构造演化的研究成果,探讨四套主要成矿系统的成因类型、成矿构造背景及其对钦杭结合带构造演化的启示.其中,广东云浮硫铁矿产于震旦系大绀山组,块状和条带状矿石呈层状产于火山沉积岩系中,是一套与海底热液活动密切相关的VMS成矿系统,形成于新元古代俯冲相关的弧后(间)拉张盆地;盘龙铅锌矿产于泥盆系上伦组,角砾状和胶状矿石产于浅海相白云质碎屑岩中,是一套加里东期被动大陆边缘的SEDEX型铅锌成矿系统;河台金矿田赋存于震旦系乐昌组,脉状矿体严格受断裂和蚀变带控制,是一套变质热液主导的造山型金矿成矿系统,形成于印支-燕山期陆内走滑或陆陆碰撞背景;圆珠顶铜钼矿床形成与燕山期(155Ma)二长花岗斑岩密切相关,细脉浸染状矿石赋存于岩体的内外接触带,是一套陆内伸展背景的斑岩铜钼成矿系统.总体而言,粤西-桂东地区经历了新元古代俯冲、加里东期被动大陆边缘、印支期陆内走滑(或陆陆碰撞)和燕山期陆内伸展四个重要的构造事件,这与钦杭结合带总体构造演化过程一致.%The area of West Guangdong-East Guangxi is one of the important base providing large amounts of gold,silver,copper,molybdenum,lead,zinc and pyrite,etc.Four main series of ore-forming systems in this area are distinguished.The Dajiangping pyrite deposit,hosted in the Daganshan Formation,is consisted of massive and banded ores,which possibly represent a VMS mineralization system form in a Neoproterozoic back-arc basin.The Panlong sedimentary exhalative (SEDEX) Pb-Zn deposit is hosted in the marinecalcite of Devonian Shanglun Formation,interpreted to be formed in a passive continental margin.The Hetai gold deposit in hosted in silicified fracture zones of Sinian metamorphic rocks,which is a typical orogenic gold deposit formed in the Indosinian to Yanshanian collisional or strike-slipping setting.The Yuanzhuding Cu-Mo deposit is related to porphyry granite and formed at 155Ma intracontinental extensive setting.Combining with the published tectonic evolution and geochronological data,the area of West Guangdong and East Guangxi have experienced Neoproterozoic subduction,Devonian passive continental margin,Indosinian-Yanshanian collision (or strike-slip) and Late Yanshanian intra-continental extension,which maybe code the Qinzhou-Hangzhou joint belt also experiencing the similar tectonic evolutior.

    • 摘要: 河南省大地构造单元涉及华北陆块、秦岭造山带和扬子陆块.前中侏罗世华北陆块区的大地构造单元划分在省内外基本上形成了共识,而有关秦岭造山带构造单元的划分存在较大分歧,许多岩石地层单位具有跨代性.根据大地构造演化特征和新发表的同位素年龄数据,将各大地构造单元划分为10个构造演化阶段,各阶段均形成了优势大地构造相和相应的矿产资源.在一定的大地构造演化阶段、一定的大地构造相分布一定的矿产或矿床组合,不同大地构造单元各个构造阶段的相系清晰反映了矿床的空间分布规律.根据矿床形成的地质构造环境、成矿作用等特征,将河南省众多矿床厘定出27个矿床成矿系列.文章基于大地构造演化进行矿床成矿系列的划分是一种新的探索.%Tectonic units in Henan Province are composed of North China Block,Qinling Orogenic Belt and Yangtze Block.There is a consensus on the tectonic unit division of the North China Block in pre-middle Jurassic in Henan Province.However,the debate on the division of tectonic units of Qinling Orogenic Belt has never stopped because of the cross-generation nature of rock-stratigraphic unit.In this paper,according to the characteristics of tectonic evolution and newly published isotope age data,the authors divided tectonic evolution into 10 stages with different dominant tectonic facies and mineral resources.The spatial distribution of ore deposits is clearly reflected by the mineral or mineral deposit association which formed in a certain geotectonic evolution stage and geotectonic facies and tectonic facies series developed in each tectonic stage in different tectonic units.According to the geological tectonic environment of ore deposits and mineralization characteristics,27 metallogenic series of mineral deposits were set up in Henan Province.The division of metallogenic series of ore deposits based on geotectonic evolution in this paper is a new kind of exploration.

    • 摘要: 本文系统收集整理了近年来与山东省境内麻粒岩有关的研究资料,将山东省麻粒岩划分为沂水麻粒岩带、平度-栖霞麻粒岩带、海阳所-威海麻粒岩带三个麻粒岩相带,总结了各带的地质概况、变质温压条件及P-T-t轨迹、变质时代及演化过程,探讨了麻粒岩的成因.认为山东省各麻粒岩带均是多期次麻粒岩相变质作用的产物,其中2.7Ga、2.5Ga两期麻粒岩相变质作用均为中低压条件下的产物,发生时间与区内TTG的形成时间较为一致,P-T-t轨迹为逆时针型,反映当时形成的大地构造背景为地幔底辟引发的拉张环境;而1.9Ga、210Ma两期麻粒岩相变质作用则高压、中低压麻粒岩都有,反映其非均质变质环境的特点,P-T-t轨迹为顺时针型,指示其与俯冲-碰撞造山过程有关.其中1.9Ga期与古元古代胶辽吉活动带发生俯冲-碰撞造山过程有关,而210Ma期则是华北-扬子两大板块三叠纪碰撞产生的榴辉岩的退变质产物.结合省内基础地质研究的最新进展,对山东省前寒武纪大地构造演化作了部分探讨,并建立了年代学格架.认为平度-栖霞麻粒岩带古元古代高压麻粒岩相变质和苏鲁超高压变质带三叠纪的榴辉岩相变质事件可能是胶东地区太古宙绿岩带金元素活化迁移并在中生代成矿的决定性因素.山东省太古宙大地构造演化具有一定的旋回性,每个旋回由绿岩带-基性-超基性侵入体-TTG花岗岩类-热变质事件组成,很好地符合TTG的玄武质岩浆底侵成因模式.自1.9Ga才有高压麻粒岩的形成,暗示了具有一定规模的板块之间的俯冲活动始于1.9Ga之前的古元古代.鲁西陆块与胶辽陆块在古元古代可能并不是两个完全独立的块体,其巨大差异可能是由于两个陆块的大地构造位置差异和后期抬升剥蚀程度不同而引起.
