Abstract This study presents a low‐temperature thermochronological data set from the Jiaodong Peninsula in eastern China, including new zircon U‐Th/He and apatite fission‐track Sulu Terrane side of published Jiaobei Uplift to west. These reveal differential tectonic evolution between Terrane, which is responsible for their heterogeneous gold endowment. Thermal history inverse modeling structural analysis indicate three broad periods cooling Terrane. include: (a) slow 114 50 Ma; (b) rapid 40...
Jiaodong is the largest gold deposit concentration area in China. In recent years, great breakthroughs have been made deep prospecting, and it has become third of deposits world. A series prospecting discoveries provided basic conditions for summarizing regional metallogenic law, constructing model, carrying out research on genesis innovating theory. The are mainly distributed Northwest Jiaodong, Qi-Peng-Fu Mu-Ru regions, occur Precambrian metamorphic rock series, Jurassic Linglong-type...
焦家金矿是胶东蚀变岩型金矿的典型代表，金储量超过200t。矿体受焦家主干断裂控制，呈脉状产出，发育钾化、绢英岩化、硅化和碳酸盐化等蚀变，矿石中主要载金矿物为黄铁矿。热液成矿期主要可分为四个阶段：黄铁矿-石英阶段（ⅰ）、金-石英-黄铁矿阶段（ⅱ）、金-石英-多金属硫化物阶段（ⅲ）和石英-碳酸盐阶段（ⅳ）。本文选取焦家金矿床深部I号主矿体为研究对象，采集了不同标高（-600~-1100m）的钻孔岩心样品，分析了黄铁矿的微量元素和S-He-Ar同位素组成，以此讨论成矿流体的组成、性质及来源。研究发现：焦家深部I号矿体黄铁矿呈浅黄色，强金属光泽，自形-半自形粒状结构，粒度50~1000μm，呈浸染状-细脉状分布于黄铁绢英岩化碎裂岩中，为第ii成矿阶段的产物。黄铁矿的稀土元素含量较低，ΣREE为3.27×10-6~38.5×10-6，富集轻稀土元素，δCe值为0.81~1.05，δEu值为0.67~1.43，Th/La、Nb/La比值均小于1，指示成矿流体为富Cl的还原性流体。Co/Ni比值介于0.54~1.57之间，平均值为0.99，与变质流体相近；Y/Ho比值在21.9~35.5之间，...
Obtaining geological information at depth by lower-cost proxies is important. Apatite grains from hydrothermal quartz veins and their host K-feldspar altered granites the Jiaodong gold province reveal key insights into buried rocks vertical distribution of ores depth. Two types apatite are identified. Type I in coexist with amphibole feldspar, indicating a magmatic origin. They yield U-Pb Tera–Wasserburg concordia lower intercept dates 162 ± 13 Ma 158 9 Ma, which within uncertainty zircon...
The intrusive age ranges of Linglong, Guojialing, Weideshan, and Laoshan granites in the Jiaodong Peninsula are 155–154 Ma, 131–130 118–111 116 respectively. Together with Shidao granite (227–200 Ma), five phases magmatism can be classified by time, all which have different degrees gold polymetallic mineralization. type evolved from A–, S–type to I–, A–type Late Triassic Early Cretaceous, thus reflects evolution geodynamics Mesozoic, indicating switch North China Craton (NCC)–Yangtze (YC)...
胶东是我国最大的金矿集中区,累计探明金资源量5000余吨,焦家式蚀变岩型金矿床提供了80%以上的金资源量,钾长石化和黄铁绢英岩化蚀变是该类矿床的重要找矿标志,但对其成因与形成时限缺乏有效约束。为探究两类蚀变的成因并限定其形成年龄,本文对典型蚀变岩型金矿床中钾长石化花岗岩与黄铁绢英岩化碎裂岩进行锆石和磷灰石LA-ICP-MS...
The late Mesozoic destruction of the eastern North China Craton (NCC) resulted from intense crust-mantle interaction, culminating in formation world-class gold deposits Jiaodong Peninsula at ca. 120 Ma. We present zircon U-Pb geochronological data, Hf isotopic compositions, whole-rock major and trace element, Sr-Nd-Pb compositions for two suites granitoids: one (the Linglong suite) that hosts significant mineralization other Weideshan is largely unmineralized. suite was emplaced Late...
The Liaoshang gold deposit in the Jiaodong area of Shandong Province is best known for its super‐large size. Situated on north‐eastern margin Jiaolai Basin, it forms a part Jiaobei terrane North China Block. Approximately 20 ore bodies within have been explored; these, four are structurally controlled gold‐bearing pyrite–dolomite vein‐type deposits. These lie an NE‐trending altered fracture zone and characterized by their thickness high‐grade ores. wall rocks consist Paleoproterozoic...
The Jiaodong gold province is one of the most important fields globally and largest in China. Denggezhuang deposit situated eastern portion Muping metallogenic belt, within province. Despite many recent investigations, detailed mineralogical studies, particularly on auriferous minerals such as pyrite, are lacking. Therefore, further constraints occurrence mode source necessary for this deposit. This study employed situ laser ablation (multi-collector) inductively coupled plasma mass...
The Panzijian gold deposit is located in the Jiaobei uplift on eastern margin of North China Craton. It a quartz vein-type southern end Qixia-Penglai ore belt. In order to explore source and properties ore-forming fluids materials deposit, process reveal genesis this work has carried out petrographic observation temperature measurement gold-bearing fluid inclusions, laser Raman experiment, H–O isotope study, pyrite Pb study. Panjian divided into four metallogenic stages stage Ⅲ main...
