The Yangbishan iron-tungsten deposit in the Shuangyashan area of Heilongjiang Province is located in the center of the Jiamusi Massif in northeastern China. The rare earth element and trace element compositions of the scheelite show that it formed in a reducing environment and inherited the rare earth element features of the ore-forming fluid. The geochemical characteristics of the gneissic granite associated with the tungsten mineralization show that the magma formed in this reducing environment and originated from the partial melting of metamorphosed shale that contained organic carbon and was enriched with tungsten. In addition, in situ Hf isotopic analysis of zircons from the gneissic granite indicates that they probably originated from the partial melting of a predominantly Paleo-Mesoproterozoic crustal source. According to LA-ICP-MS zircon dating, the Yangbishan ore- related gneissic granite has an Early Paleozoic crystallization age of 520.6 ＋ 2.8 Ma. This study, together with previous data, indicates that the massifs of northeastern China, including Erguna, Xing＇an, Songliao, Jiamusi, and Khanka massifs, belonged to an orogenic belt that existed along the southern margin of the Siberian Craton during the late Pan-African period. The significant continental movements of this orogeny resulted in widespread magmatic activity in northeastern China from 530 Ma to 470 Ma under a tectonic setting that transitioned from compressional syn-collision to extensional post- collision.

Acta Geologica Sinica(English Edition) 2012年第3期86卷 619-629页

作者： REN Yunsheng JU Nan zhao hualei WANG Hui HOU Kejun LIU Shen College of Earth Sciences Jilin UniversityChangchun 130061China MRL Key Laboratory of Metallogeny and Mineral Assessment Institute of Mineral ResourcesChinese Academy of Geological SciencesBeijing 100037China State Key Laboratory of Ore Deposit Geochemistry Institute of GeochemistryChinese Academy of SciencesGuiyang 550002China

The metallogenetic porphyry bodies in the Nongping Au-Cu deposit, in the eastern Yanbian area, mainly include porphyritic granodiorite and biotite granodiorite porphyry. They are featured with high silicon and enrichment in sodium, and classified into sodic rocks of low-K tholeiitic basalt series. Except slightly low Sr content, the rock basically has the geochemical characteristics of the adakite： relatively high A12O3 content, relatively low MgO content, depletion in Y and Yb; relative enrichment in large ion lithophile elements （LILEs） and light rare-earth elements （LREEs）, relatively low content of high field strength elements （HFSEs）; positive Eu anomaly or weak negative Eu anomaly. In situ zircon dating technology LA-MC-ICP-MS was used to conduct single-grain zircon dating of biotite granodiorite porphyry, and the results show that the age of metallogenetic porphyry body is 100.04±0.88 Ma, indicating that the porphyry bodies were emplaced in the late Cretaceous period. According to the regional tectonic setting and the comparison with the same kind of deposits, we think that the metallogenetic porphyry bodies in the Nongping Au-Cu deposit have a close genetic connection with the subduction of the Pacific plate in the late Yanshanian period. The adakitic magma generated from partial melting of the subducting plate has high formation temperature, high oxygen fugacity, and volatile constituents＇ enrichment, so it is helpful for enrichment of metallogenetic elements and plays an important role in the formation of porphyry Au-Cu deposits in this region.

The exploration depth of sandstone-type uranium deposits worldwide is mostly less than 700 m,and most of them occur in strata of fluvial facies(Adams et al.,1981;Jin et al.,2016;Hou et al.,2017).Only a few small uranium deposits have been reported in aeolian depositional environments(Isachsen et al.,1955;Li et al.,2001).In the Pcngyang Jingchuan region of the southwestern Ordos Basin,uranium ore bodies with large thickness and high grade in the aeolian sandstone of the Luohe Formation were newly found at depths from 700 to 1500 m,which have laid the foundation for increasing the uranium resources significantly in the Ordos Basin.

In Northern China, sandstone-type uranium （U） deposits are mostly developed in Mesozoic-Cenozoic basins. These U deposits are usually hosted in unvarying horizons within the basins and exhibit typical U-forming sedimentary associations, which is referred to as U-bearing rock series. This study describes the structural features of U-bearing rock series within the main Mesozoic-Cenozoic U-producing continental basins in Kazakhstan, Uzbekistan, and Russia in the western segment of the Central Asian Metallogenic Belt （CAMB）, and Northern China in the eastern segment of the CAMB. We analyze the basic structural conditions and sedimentary environments of U-bearing rock series in Northern China and classify their structural styles in typical basins into river valley, basin margin, and intrabasin uplift margin types. The intrabasin uplift margin structural style proposed in this study can be used to indicate directions for the exploration of sandstone-type U deposits hosted in the center of a basin. At the same time, the study of structural style provides a new idea for exploring sandstone-type U deposits in Mesozoic-Cenozoic basins and it is of great significance to prospecting of sandstone-type uranium deposits.

砂岩型铀矿作为一种以表生流体作用为主的后生矿床,发育较多低温矿物。甘肃省彭阳铀矿是近年来新发现的一处深部砂岩型铀矿床,具有砂体规模大、铀矿化面积广、厚度大、等特点。在含矿层及周边发育方解石、石膏、黄铁矿、黏土矿物等低温成因矿物,研究矿物的空间分布特征及其与铀矿物的关系,对判别成矿流体的主要来源、性质以及对铀成矿的控制作用具有重要意义。近红外岩心光谱扫描技术可无损、快速、批量地识别出岩心中的层状硅酸盐矿物(如高岭石、蒙脱石、绢云母等),硫酸盐矿物(如石膏、明矾石等),碳酸盐矿物(如方解石、白云石等)等矿物信息,本文基于该技术对彭阳铀矿床的矿物类型及其组合进行研究。结果表明:洛河组发育高岭石、蒙脱石、伊利石(伊/蒙混层)、绿泥石、碳酸盐、石膏、铁氧化物等矿物,铀矿段的矿物组合为“伊利石(伊/蒙混层)+石膏+碳酸盐”,局部可见高岭石。根据矿物组合特征反演流体作用,洛河组含铀矿段矿在沉积期主要是一套碱性环境,成矿期存在还原性酸性流体的注入。
