The Altaid tectonic collage extends over Central Asia, exposing numerous accretionary orogens that can account for the Palaeozoic continental crust growth. A pluridisciplinary approach, using geochronological, geochemical, structural and palaeomagnetic tools was carried out to unravel the architecture and the evolution of West Junggar(Northwestern China), a segment of the Altaid Collage. A polycyclic geodynamic evolution is inferred and includes:(1) an Early Palaeozoic cycle, characterized by the closure of two oceanic basins bounded by island-arc systems;(2) an Early Devonian subduction jamming resulting in a minor-scale collision documented by thrusting, syntectonic sedimentation and subsequent crutal thinning associated with alkaline magmatism;(3) a Late Palaeozoic cycle, driven by the evolution of two opposite subduction zones developed upon the Early Palaeozoic basement. Detailed structural analysis and paleomagnetic data provide constraints for the late evolution of Junggar in the frame of the development of the Late Palaeozoic Kazakh orocline, which led to oblique subduction and transpression in the West Junggar accretionary complex. Progressive buckling of the Kazakh orocline further resulted in Late Carboniferous to Permian wrench tectonics, and lateral displacement of lithotectonic units. Block rotations that continued after the Late Triassic are due to diachronous intraplate reactivation. This scenario mirrors the Palaeozoic geodynamics of the Altaid Collage. Multiple Early Palaeozoic collisions of intra-oceanic arcs and micro continents have contributed to the formation of the Kazakhstan Microcontinent. Since the Late Palaeozoic, subductions formed around this microcontinent and the final oblique closure of oceanic domains resulted in the transcurrent collage of Tarim and Siberia cratons. Palaeozoic strike-slip faults were later reactivated during Mesozoic intracontinental tectonics.

SHRIMP zircon U-Pb age, fitho- and biostratigraphic analyses of the Huaiyu Domain in South China,— Evidence for a Neoproterozoic orogen, not Late Paleozoic-Early Mesozoic collision

In the last few decades, the Late Paleozoic-Early Mesozoic tectonic evolution of South China has been quite controversial. The focus of debate is on both the age of ophiolites and the Late Paleozoic-Early Mesozoic geological and geodynamic environment. The Huaiyu Domain is located in the NE part of South China and exposes numerous significant geological features that are keys to understand the tectonics of South China. In this paper, we present some new evidence on stratigraphy, petrology and SHRIMP zircon U-Pb geochronology, and together with other geological and geochemical data available in the literature, and the following conclusions are suggested: 1) The eastern Jiangnan ophiolites belt, dated at 858±11 Ma by SHRIMP zircon U-Pb method, was generated during the Neoproterozoic, but not the Late Paleozoic; 2) The sedimentary rocks associated with these oceanic rocks do not contain radiolarians but Neoproterozoic acritarchs; 3) During Permian-Early Triassic times, the Huaiyu Domain was dominantly characterized by a shallow sea depositional environment since deep sea sediments are absent; and 4) The pre-Devonian tectonics of South China has been reworked by late polyphase tectonism through the Triassic and the Cretaceous periods. A Late Paleozoic-Early Mesozoic deep marine domain floored by oceanic crust never existed in the study area. The geochronological and structural data do not comply with a Late Paleozoic-Early Mesozoic South China Ocean.

Polyorogenic evolution of the Paleoproterozoic Trans-North China Belt--New insights from the Luliangshan-Hengshan-Wutaishan and Fuping massifs

E.-Bataillon F-34095 Montpellier Cedex France.

The Trans-North China Belt (TNCB) is a Paleoproterozoic collisional orogen (ca. 1.9-1.8 Ga) responsible for the amalgamation of the North China Craton. Detailed field works in Lüliangshan, Hengshan, Wutaishan and Fuping massifs where the belt is well exposed, allow us to draw a new tectonic map and crustal-scale cross sections. The available petrologic, radiometric, geochronologic data are integrated in a geodynamic evolution scheme for this orogen. The Low Grade Mafic Unit (LGMU) is interpreted as an ophiolitic nappe rooted in a suture zone located in the western part of the Lüliangshan. This ophiolitic nappe overthrusts to the SE upon the Orthogneiss-Volcanites Unit (OVU) that consists of a bimodal volcanic-sedimentary series metamorphosed under amphibolite facies conditions intruded by calcalkaline orthogneiss. The OVU is a composite Neoarchean-Paleoproterozoic magmatic arc developed during two stages (ca. 2500 and 2100 Ma) upon a continental basement corresponding to the western extension of the Neoarchean Fuping massif. The OVU overthrusts to the SE the Fuping massif along the Longquanguan shear zone. This stack of nappes, coeval with an amphibolite facies metamorphism, is dated at ca. 1880 Ma. Subsequently, the metamorphic series experienced a widespread migmatization at 1850 Ma and was intruded by post-orogenic plutons dated at 1800 Ma. The weakly to unmetamorphosed Hutuo Supergroup unconformably overlies the metamorphosed and ductilely deformed units (OVU and LGMU), but it is also involved in a second tectonic phase developed in subsurface conditions. These structural features lead us to question the ca. 2090 Ma age attributed to the Hutuo supergroup. Moreover, in the Fuping massif, several structural and magmatic lines of evidence argue for an earlier orogenic event at ca. 2100 Ma that we relate to an older west-directed subduction below the Fuping Block. The Taihangshan Fault might be the location of a possible suture zone between the Fuping Block and an e

雪峰山-九岭造山带位于华南板块的中心区域,是一条典型的陆内造山带。通过详细的野外地质观察,雪峰山在早中生代经历了3期构造变形：D1为上部指向NW的韧性剪切,D2代表了一期反向褶皱-逆冲构造事件,以及D3期的水平挤压形成的直立的褶皱、劈理和线理。而在九岭,早中生代大规模脆-韧性域构造变形叠加在早古生代韧性变形之上,形成了一系列极性NW逆冲断层和不对称褶皱。雪峰山-九岭陆内造山带形成于早中生代,造山作用可以分为两个阶段,即245~225Ma的挤压变形阶段和225~215Ma的垮塌-岩浆侵位阶段。雪峰山-九岭造山带的构造特点表明,华南板块东南缘古太平洋板块向北西方向的俯冲可能引发了早中生代的陆内造山过程。

博罗霍努岩体是发育在新疆伊犁北部的一个大型海西期花岗岩体,总体沿近 SE—NW 向分布,出露面积逾2000km^2。该岩体主要包括三类花岗岩:灰黑色辉石闪长岩、浅色黑云母花岗岩和紫红色黑云母钾长花岗岩。锆石 U—Pb La-ICP-MS 定年表明,辉石闪长岩的年龄为301±7Ma,黑云母花岗岩的年龄范围为294±7～285±7Ma,而黑云母钾长花岗岩则形成于280±5～266±6Ma。岩石地球化学分析显示,黑云母花岗岩和钾长花岗岩以准铝或弱过铝Ⅰ型花岗岩为主,个别属于弱过铝 S 型花岗岩。在微量元素方面,这些花岗岩均富集轻稀土而亏损重稀土,但来自两个剖面的花岗岩具有不同的稀土元素配分模式,可能代表它们的岩浆源区有所不同,因此需要进一步对这些花岗岩进行同位素地质学研究。相对于洋脊花岗岩而言,博罗霍努岩体的花岗岩明显富集 K,Rb,Ba 和 Th,同时,显著亏损 Nb,Ta,Y 和 Yh。以上地球化学特征及微量元素判别图表明,这些花岗岩类形成于俯冲有关的火山岛弧环境。结合伊犁及邻区岩浆岩的特征及其时代,可以认为博罗霍努岩体的形成与天山北部洋壳向南的俯冲造山作用有关。西天山北部俯冲造山作用最终在中二叠世结束,并在中一晚二叠世进入陆内造山和伸展拉张阶段。

活动大陆边缘的构造演化如何响应大洋俯冲是一个地球科学界感兴趣的问题。晚中生代东亚大陆边缘因受古太平洋俯冲影响深远而成为该问题重要的天然实验室。然而古太平洋的俯冲历史还存在较多争议,有晚中生代俯冲角度变陡、侏罗纪断离拆沉及之后的回卷后撤,以及晚中生代俯冲角度多次变化等观点,另外古太平洋俯冲时是否携带微陆块与仰冲的东亚大陆发生碰撞目前也存在争议。

雪峰山主体地处湖南省境内,位于华南板块的中心区域,是一条典型的陆内造山带。通过详细的野外地质观察,我们将其分为3个构造单元:西部外区,主要以大型箱状褶皱为主;中部区,与西部区以主逆冲断层相分隔,劈理发育呈扇状,是雪峰山构造带的核心区域,也是变质级别最深、变形最强的区域;东部区,变形集中在脆韧性区域之上,以极性北西构造为主,并有反向构造发育。研究区经历了3期构造变形:D_1为上部指向北西的韧性剪切,广泛发育于整个区域;D_2代表了一期反向褶皱—逆冲构造事件;D_3则以水平挤压为主,形成了直立的褶皱、劈理和线理。雪峰山的构造演化表明华南板块东南缘古太平洋板块向北西方向的俯冲可能引发了早中生代的陆内俯冲造山过程。

越南东北部-海南岛-粤西南构造带整体上呈NW-SE走向展布于华南板块的南缘,是理解华南构造演化的关键地区。作为印支运动代表性地区的越南东北部地区Song Chay构造带上,下古生界浅变质沉积岩、上古生界至早-中三叠世未变质的沉积盖层中都发育向北东逆冲推覆,韧性变形域表现为NE-SW向的矿物拉伸线理和上部指NE的剪切变形,而脆性变形域则记录了大量NE极性的褶皱和冲断构造。两广交界的云开地体和海南岛地区存在着相同样式的构造变形。关于这期变形的时间,本文通过对野外地层以及所出露不同时期岩体变形特征的综合研究,并结合高质量的锆石U-Pb年代学数据,在越南的东北部厘定为237～228Ma。这期广泛分布于华南板块南缘构造事件的动力学机制同Day Nui Con Voi(大象山)微陆块与华南板块在早中生代的构造拼合事件相关。本文认为华南板块在早三叠世开始沿着越南东北部的Song Chay缝合带俯冲拼合于Day Nui Con Voi微陆块之下,因此在早-中三叠世时期,在作为俯冲盘的华南板块南缘发育一系列的褶皱和逆冲推覆构造,晚三叠世印支造山作用结束。因此,华南板块南缘的越南东北部-海南岛-粤西南构造带被一同卷入早-中三叠世同印支板块的碰撞造山体系之中。
