中文摘要:庐枞矿集区是长江中下游成矿带内重要的铁铜矿集区，产出一系列典型的玢岩型铁矿床和斑岩型铜矿床。最近在庐枞矿集区北部东顾山地区，首次发现了钨多金属矿床，这是在长江中下游成矿带长江以北首次发现的钨矿化，为矽卡岩型。钨矿化主要呈浸染状或脉状产于东顾山岩体（黑云母花岗岩）与奥陶系（白云质灰岩）的接触带或大理岩层间破碎带中。矿石矿物主要为白钨矿及钼、铜、铅锌硫化物。钨矿化主要发育在华南地区，近年来在长江中下游成矿带的过渡带及以南的扬子地块如江南隆起等地发现多个新的大型钨矿床，但在长江以北地区一直未曾发现。庐枞矿集区北部东顾山钨矿床的发现，指明长江中下游成矿带燕山期除铁、铜大规模成矿作用以外，也有钨的成矿作用，指示该区具有良好的钨矿找矿前景。在长江中下游成矿带的其他矿集区要重视和加强钨矿化的成矿作用研究和找矿工作。
Abstract:The Luzong orefield in the Middle-Lower Yangtze River Valley Metallogenic Belt is an important area that possesses a series of porphyritic iron deposits and porphyry copper deposits. The Donggushan tungsten-molybdenum polymetallic deposit was recently discovered in the north of the Luzong orefield. This is the first discovery of tungsten mineralization north of the Yangtze River along the Middle-Lower Yangtze River Valley Metallogenic Belt. The dominant disseminated tungsten mineralization occurs along the contract zone between biotite granite and Ordovician dolomite limestone or marble. The main tungsten mineral is scheelite that occurs in metamorphosed dolomitic limestone together with Mo-Cu-Pb-Zn minerals and skarn minerals. Tungsten mineralization mainly occurs in southern China; several new large-sized tungsten ore deposits have been found in the Yangtze block in recent years, e.g., in the Jiangnan uplift belt in the south of the Middle-Lower Yangtze River Valley Metallogenic Belt. There are reports of tungsten deposits in the E'dongnan and Tongling orefields, but tungsten deposits was not previously found north of the Yangtze River. The discovery of the Donggushan tungsten deposit indicates that the Middle-Lower Yangtze River Valley Metallogenic Belt hosts significant tungsten deposits as well as iron and copper deposits of Yanshanian age. It also highlights the potential of the Middle-Lower Yangtze River Valley Metallogenic Belt for hosting additional tungsten deposits, and justifies a greater emphasis on tungsten mineralization in both metallogenic studies and minerals exploration in other mineralized areas in the Middle-Lower Yangtze River Valley Metallogenic Belt.
