行洛坑花岗岩出露面积虽然仅有0.128平方公里,却以全岩式矿化著称,其中赋存着特大型钨矿床,并伴生中型的钼(铋)矿床,引起中、外地质学者的注视。本文从地球化学角度,着重讨论行洛坑花岗岩的化学成分、元素演化、找矿地球化学标志、成矿元素存在形式及成因等问题。 Although only 0.128 km2, the exposed area of ​​granite in Xingluo Hang is well known for its all-rock mineralization, in which ultra-large tungsten deposits and accompanying molybdenum (bismuth) deposits are found, causing the attention of Chinese and foreign geologists . In this paper, from the geochemical point of view, we mainly discuss the chemical composition, elemental evolution, ore-bearing geochemical signs, the existing forms of ore-forming elements and their genesis in Xingliaokeng granite.
