青海帕龙地区多金属矿资源潜力评价

帕龙地区化探反映的成矿元素主要为与高中温有关,结合区内地层、岩浆岩分布及化探特征考虑,其成矿特征和同一成矿地质位置的矽卡岩型小卧龙铁多金属矿相类似,而小卧龙则是一个含钨锡铜铅(银)锌的矽卡岩型铁矿床,具有中型钨锡矿床资源前景。为此,以物探电、磁法为手段,初步评价帕龙地区多金属矿资源潜力,以寻找中高温多金属矿床存在的找矿线索,主攻小卧龙型矽卡岩矿床湿矽卡岩阶段形成的铁、钨锡矿体和硫化物阶段形成的铜铅(银)锌、金矿体,确定多金属矿的开发利用前景,为该地区金属矿产资源开发提供研究基础。

Potential Evaluation of Polymetallic Ore Resources in Palong Area of Qinghai Province

The metallogenic elements reflected by geochemical exploration in Palong area are mainly related to high and medium temperature. Considering the strata, magmatic rock distribution and geochemical exploration characteristics in the area, the metallogenic characteristics are similar to the skarnXiaowolong iron polymetallic deposit of the same tectonicl location, while XiaowolongOre is a SKARN-TYPE iron deposit containing W, Sn, Cu,Pb(Ag) and Zinc, which has the resource prospects of mediumsized W-Sn deposit. Therefore, the potential of polymetallic ore resources in Palong area is preliminarily evaluated by means of geophysical electric and magnetic methods.Based on the medium and high temperature polymetallic ore as the prospecting clue, this paper mainly focuses on the iron, tungsten, tin ore bodies formed in the wet skarn stage and the copper, lead(silver), zinc and gold ore bodies formed in the sulfide stage of the xiaowolongskarn deposit,and determines the development and utilization prospect of the polymetallic ore, so as to provide the research basis for the development of the metal mineral resources in this area.
