青海省敦德夏拉郭勒地区铁铜钼多金属矿找矿方向及前景探讨

敦得夏拉郭勒铁铜钼多金属矿具有良好的成矿地质背景条件.目前已发现了矽卡岩型磁铁矿体7条,钼矿化体2条,黄铜矿化体2条,斑岩型铜钼矿化体1条,地表铜钼矿化线索4处。该矿受矽卡岩控制,多形成于岩体与大理岩的接触部位。通过对矿化类型、矿(化)体特征和找矿标志的研究,总结了矿区的矿化分带,蚀变分带,认为该地区矿床类型属于矽卡岩-斑岩型,推测深部可能存在成矿斑岩体,具有进一步找矿前景。

Prospecting directions and development prospects of Fe-Cu-Mo polymetallic ore in Dunde Xiala Guole, Qinghai province

Dunde Xiala Guole Fe-Cu-Mo polymetallic ore has the good ore-forming geological conditions. At present, it has been found the number of skarn-type magnetite ore bodies, molybdenum ore bodies and brass mineralized bodies are 7, 2 and 2, respectively. And it has been also found one porphyry copper molybdenum mineralization body and four surface copper molybdenum mineralization clues. This ore is controlled by skarn, and it is formed in contact parts between rock mass and marble. This paper summarizes the mineralization zonation and alteration zoning through the study of mineralization types, ore body characteristics and prospecting indicators. It is thought this ore belongs to skarn-porphyry type and speculated there possibly exists metallogenetic porphyry. This ore is with a further prospecting potential.
