摘要
红太平多金属矿床产于延边古生代地槽区二叠系海相火山岩中及其与碎屑沉积岩的过渡带上。矿体呈层状,矿石具典型的沉积构造,矿石硫同位素组成与国内变质火山岩铜矿床相似,气液包裹体氢氧同位素组成介于大气循环水和变质水之间。因此,初步认为矿床属与火山热液或热泉活动有关的块状硫化物型矿床。
The Hongtaiping polymetallic deposit lies in the Permian marine volcanic rocks, Palaeozoic geosyncline and the transitional belt of the clastic sedimentrary rocks in the Yanbian area. S-isotopic components in the ore with typic sedimentary structures are similar to those of metamorphic volcanic copper deposit. The ore bodies occurred as stratification. The isotopic components of hydrogen and oxygen of gas-liquid inclusions are between those of atmospheric water and metamorphic water. Therefore, it is preliminarily considered that it belongs to massive sulfide deposit related to the voloanic hydrothermal solutions or activities of the hot springs.
