The continental margin of Palaeozoic Era in the north Side of North China Platform underwent mainly three Phases of tectonic evolution. Among which there were two plate activities, transformation from geosyncline to platform and continental crust creation in Early Palaeozoic Era. The connection of the created continental crust in the north margin of the Nerth China Platform with created continental crust in the south margin of the Siberia Platform took place from the Late Devonian Epoch to Ear-y Carboniferous...

The continental margin of Palaeozoic Era in the north Side of North China Platform underwent mainly three Phases of tectonic evolution. Among which there were two plate activities, transformation from geosyncline to platform and continental crust creation in Early Palaeozoic Era. The connection of the created continental crust in the north margin of the Nerth China Platform with created continental crust in the south margin of the Siberia Platform took place from the Late Devonian Epoch to Ear-y Carboniferous Epoch. The partition belt was located the Halatumiao line in the north of Hegenshan—Erlianhaote, Inner Mongolia, and further westward the belt linked with the Mid—Palaeozoic ophiolite belt of the northern margin of Tianshan Mountain, Mongolia Gobi. The ages of the three ophiolite belts in the Palaeczcie folded region of Inner Mongolia tended to be younger in proper order northwards, which were Carmbrian, Ordovician period and Late Devonian—Early Carboniferous epoch respectively. The duration of the corresponding tectonic emplacement or underthrusting and connection was from Middle—Late Ordovician to Early Silurian Epoch, Middle-Iate Silurian to Early Devonician Epoch。 Late Devonician to Early Carboniferous Epoch. The research for both the forming epochcs and the geologic characteristics all of the ophioIite(belt), ancient island—arc rock Sequence, flysh formation as well as molasse formation has proved that there existed a coledonian folding belt in the north side of North China Platform whose northern border was locate in the south of the Suolun Mountain—Sunite Zuoqi—Xilinhaote. The facts above mentione have made clear that the plate underthrusting and Caledonian mountain folding displaced and developed eastwardly. The main phase of the strong tectonic movement took place at the Middle Ordovician-Late Silurian Epoch. The three tectonic evolutions in the north side of North China Platform had formed their Ore-forming series and metallogenetic belts respectively. The tectono—metallogenic series of southern belt was intergrated, which included not only the Cr—Ni, Fe-Mn-P Series associated with ophiolite formation, but also the Cu—Mo—Au series of transtional crust type. Beginning from ocean crust towards continental crust(from north to south), Fe, Cr, Cu(Me)、Au developed in turn、Each invoived a series of ore deposits and mineralized localities. The middle belt was merely a Cr-Feore Zone associated with ophiolite formation, whereas the northern belt was characterized by Cr ore.

This paper provides essential data of stratigraphical sequence, evolution, tectonic setting and geochcmical characteristics of the ophiolite suite in the North Qinling-Tongbai Caledonian tectonic-magmatic belt. It is the most typical one of five ophiolite suites situated within the different periodic tectono-magmatic zones in thc Qinling-Tongbai geosyclinal fold belt. This ophiolite suite is divided into the following units which form a stratigraphical sequence: 1. Metamorphic series, where the ultramafic complex of tectonic emplacement is situated; 2. First spilite-keratophyre-quartz keratophyre series, sheeted dikes of gabbro and diabase were emplaced within it and the lower metamorphic series; 3. Siliceous rock; 4. Flysch Formation; 5. Second spilt (partly pillow lava)-keratophyre serics where siliceous rock situated within and especially at the top of this series; 6. Bimodel volcano-sedimentary series. All of the petrographical, petrochemical, geochemical characteristics and REE pattern show that this ophiolite suite was formed in the Caledonian eugcosyncline-back-arc basin. We suggest that this ophiolite suite is autochthonous and interlayered with the eugeosynclinal sediments. The ultramafic complex was closely related to spilite-ker-atophyre series. However, it shows the feature of tectonic emplacement.

本文提供北秦岭—桐柏加里东构造—岩浆带中蛇绿岩套的地层层序,岩石化学和地球化学资料,并讨论其形成的构造背景。该蛇绿岩套地层层序自下向上可分为六个单元:(1)构造定位的超镁铁岩带;(2)第一期细碧—角斑岩系;(3)硅质岩;(4)复理石建造;(5)第二期细碧—角斑岩系;(6)火山沉积岩系。岩石学、岩石化学、地球化学及稀土模式特征均表明该岩套是在加里东优地槽——弧后盆地中形成的;火山—沉积岩系是“原地”成因的。华北和华南两古板块之间曾长期存在古海洋,并在海西期实现拼贴对接和古大洋的消失。

The gabbroic pebble-bearing greywacke and bownish-black serpentine conglomerate of the Nanmingshui Formation overlie unconformably serpentinized harzburgite and metagabbro in the Karameri paleoplate suture zone in East Junggar,Xinjiang.On the basis of ammonoid fossils newly discovered and previous data of brachiopod fossils,the age of the Nanmingshui Formation is placed between C~2_1—C_2~1.The unconformity between the Nanmingshui Formation and ophiolites indicate that the tectonic emplacement of ophiolites in the Karameri suture zone took place before the deposition of the Manmingshui Formation.This emplacement resulted from collision of the Kazakhstan pale- oplate and the Siberia paleoplate.The author considers that there might occur hidden deposits of Cr,Ni and Cu below the outcrops of the Nanmingshui Formation.

依据菊石、腕足化石资料,将南明水组的时代置于 C_1~2—C_2~1。南明水组和蛇绿岩之间的不整合表明卡拉麦里缝合带中蛇绿岩的构造侵位发生于南明水组沉积之前,这一侵位是哈萨克斯坦古板块和西伯利亚古板块碰撞的结果。笔者认为在南明水组露头下面有可能赋存 Cr、Ni、Cu 等隐伏矿床。
