The recently proved Lengshuikeng Pd—Zn—Ag Orefield has a huge amount of reserves and consists of three types of mineralization (porphyry. veined and stratabound-telescoped),With metallogenetic features of multiple genesis and a three in one combination in ore types. Its formation is related to the volcanic exhalation-hydrothermal activities of the Mesozoic continental volcanic activities in East China.

冷水坑矿田是我国近年来探明的一个特大型铅锌银矿田。成矿类型有斑岩型、脉带型和层控叠生型等三种,具多成因、多位一体的成矿特点,它的形成与我国东部中生代陆相火山活动的火山喷气—热液作用有关矿田地处孤萝山破火山口西侧断陷带内,呈北东—南西向展布。北东向及其配套断裂和燕山中期的次火山岩体均较发育,是重要的成矿和控矿条件。花岗斑岩呈舌状侵位于侏罗系上统鹅湖岭组(J,e)地层,位于F_2逆断层的下盘,是斑岩型和脉带型矿床的主要含矿围岩。层控叠生型矿床的赋矿围岩为侏罗系上统打鼓顶组下段(J,d~1)顶部的石英正长质火山角砾岩层。矿体呈层状、似层状、透镜状,严格受层位控制。矿田中除铅、锌、银外,伴生组份S、Cd、Au、Cu、In等均具综合利用价值。

The preliminary exploratory results about the basic-ultrabasic rocks of the Karakoram and western Kunlun Mts. are reported in this paper. The Kudi ultramafic rock bodies belong to the Alpine-type associations in general, but there are some differences between the Kudi bodies and the typical ophiolitic metamorphic peridotites in petrochemistry. At present, there is insufficient evidence to make a full interpretation of the formation of these bodies. The Middle Proterozoic metamorphic volcanics in Akazi section...

The preliminary exploratory results about the basic-ultrabasic rocks of the Karakoram and western Kunlun Mts. are reported in this paper. The Kudi ultramafic rock bodies belong to the Alpine-type associations in general, but there are some differences between the Kudi bodies and the typical ophiolitic metamorphic peridotites in petrochemistry. At present, there is insufficient evidence to make a full interpretation of the formation of these bodies. The Middle Proterozoic metamorphic volcanics in Akazi section may have originated in a strongly attenuated continental lithosphere. According to the discriminations of the rare element and REE geochemistry the Upper Proterozoic metamorphic mafic lavas in Yixikgou section probably are formed at a Mid-ocean ridge and present truce oceanic lithosphere. Late Paleozoic volcanics may have erupted in a continental margin area. Relative strong continental volcanic activity existed in Cenozoicera, in which especially the Quaternary continental floor volcanics may be related to the rapid uplifting of the Qinghai-X izang plateau. The occurrences, petrological and geochemical characteristics and erupting stages of the volcanics found in southern Kunlun Mts. have been discussed in detail in the paper.

本文报道了考察区若干基性-超基性岩体的初步考祭结果。库地岩体属于传统观念的阿尔卑斯型岩体,但与典型蛇绿岩中的变质橄榄岩有所差异;阿卡兹、一些克沟蚀变火山岩可能发育在大洋环境,而晚古生代火山岩大概是在大陆边缘喷出的。本区在新生代时期陆相火山活动相当频繁,其分布规律和岩石特征表明它们与青藏高原的隆升有密切的关系。文中还讨论了昆仑山南侧新生代火山岩喷发的期次。

In recent years research has shown that there exists an intermediate-acidic hypahyssal magmatic formation of recularity association of mainly dioritic rocks in Junggar region of Xingjiang. They are closely related with contemporaneous continental volcanic activity in time and in genesis. Au and Cu metallogenesis is distinctly shown. Their geological geochemical characteristics and specialization are greatly similar to those of intermediate-acidic hypahyssal intrusive rocks of mainly dioritic rock assoliated...

In recent years research has shown that there exists an intermediate-acidic hypahyssal magmatic formation of recularity association of mainly dioritic rocks in Junggar region of Xingjiang. They are closely related with contemporaneous continental volcanic activity in time and in genesis. Au and Cu metallogenesis is distinctly shown. Their geological geochemical characteristics and specialization are greatly similar to those of intermediate-acidic hypahyssal intrusive rocks of mainly dioritic rock assoliated with Cu, Fe and Au. They belong to cordillera Ⅰ-type granites formed in the environment of compressional orogeny. Just as intermediate-acidic intrusive rocks in the mid-lower reaches of Yangtze River as an important ore-forming magmatic formation in the east of China, the intermediate-acidic hypahyssal magmatic formation in East Junggar and in whole north of Xingjiang is becoming increasingly important to metallogenesis.

近年来研究证实 ,新疆东准噶尔地区存在着一套以闪长质岩石为主规律组合的中酸性浅成岩浆建造。它们在时空分布和成因上与同期陆相火山活动密切相关 ,以金、铜为主的成矿作用十分明显。其地质地球化学特征及成矿专属性 ,与长江中下游地区富产铜、铁、金 ,且也以闪长质岩石为主的中酸性浅成侵入岩类十分类似 ,同属形成于挤压造山环境下的科迪勒拉Ⅰ型花岗岩。如同长江中下游中酸性侵入岩类是我国东部重要的成矿岩浆建造一样 ,东准噶尔乃至整个新疆北部 ,这套中酸性浅成岩浆建造 ,也日益显示其重要的成矿意义
