广东始兴良源铌钽铷钨多金属矿床是近年来中国地质调查局在南岭东段地区实施钨多金属矿调查评价中找到的具有大型远景的铌钽铷钨多金属矿床。最新成果显示该矿床主要有五种矿化类型:云英岩型铌钽铷钨多金属矿、白云母化钠长石花岗岩型铌钽铷钨多金属矿、石英脉型钨矿、破碎蚀变岩型钨锡多金属矿和矽卡岩型白钨矿,且以白云母化钠长石花岗岩型铌钽铷钨多金属矿潜力最大。矿区含矿花岗岩具明显分异演化特征,自上向下为:似斑状花岗岩—中细粒黑云母花岗岩—中细粒二云母钠长石花岗岩—中细粒白云母化钠长石花岗岩—云英岩的分异演化系列;含矿花岗岩蚀变分带清晰,自上向下为:白云母化、绿泥石化和钾长石化三带,矿体以云英岩、细粒白云母化钠长石花岗岩为主,石英脉次之,矿石矿物主要有黑钨矿、白钨矿、锡石、辉钼矿、钨铅矿、钼铅矿、砷铋矿、辉铋矿、辉锑矿、褐钇铌矿、铌钽矿、方铅矿、闪锌矿、黄铜矿、黄铁矿、铀钍矿、白云母等;初步研究表明广东始兴良源铌钽铷钨多金属矿体可能为深部含矿岩浆经分异演化形成,矿床具有品位稳定、规模大的特点,成矿元素复杂,主要为Nb-Ta-Rb-W-Mo-Sn-Bi组合,并富含Be、稀土、Ag等。该矿床的发现不仅填补了南岭东段地区找矿新突破,而且对整个南岭乃至华南地区铌钽铷钨多金属矿找矿具有重要的指导作用。
Guangdong Siheung Liangyuan niobium tantalum rubidium tungsten polymetallic deposit is a niobium tantalum rubidium tungsten polymetallic deposit with large prospect found by China Geological Survey in recent years in the investigation and evaluation of the implementation of tungsten polymetallic deposits in the eastern section of Nanling. The latest results show that there are five mineralization types in this deposit: Yunyanite type niobium tantalum rubidium tungsten polymetallic ore, muscovite albite granite type niobium tantalum rubidium tungsten polymetallic ore, quartz vein type tungsten ore, broken alteration Rock type tungsten-tin polymetallic ore and skarn-type scheelite, and has the highest potential of muscovite-bearing albite granite-type niobium-tantalum-rubidium tungsten polymetallic ore. The ore-bearing granitic rocks have distinct differentiation characteristics from top to bottom: plagioclase granites - medium-fine biotite granites - medium-fine granodiorite albite granite - medium-fine granite muscovite albite granite - The evolutionary series of quartzite rocks have clear alteration zoning of ore-bearing granite. The ore-bearing granite alteration zoning is clear from top to down: muscovite, chloritization and potash feldspathification; Feldspar granite-based, followed by the quartz veins, ore minerals are mainly tungsten, scheelite, cassiterite, molybdenite, tungsten lead, molybdenum lead, arsenic bismuth, bismuth, stibnite, Brown yttrium-niobium ore, niobium-tantalum ore, galena, sphalerite, chalcopyrite, pyrite, uranium-thorium ore and muscovite. Preliminary studies have shown that the Niobium, Tantalum, The deep ore-bearing magma is formed by differentiation and evolution. The ore deposit is characterized by stable grade and large scale. The ore-forming elements are complex and mainly consist of Nb-Ta-Rb-W-Mo-Sn-Bi and are rich in Be, Wait. The discovery of this deposit not only fills in the new exploration breakthrough in the area east of Nanling, but also plays an important guiding role in the prospecting of the niobium tantalum rubidium tungsten polymetallic deposits in the whole Nanling area and even in southern China.
