青海省矿产资源发育特征概述

通过对青海省矿产资源发育特征的系统研究,发现青海省矿产资源丰富,种类齐全。截止2007年底,共发现各类矿产132种,其中探明有资源储量的矿产为107种;发现各类矿床、矿（化）点3921处,其中重要矿产大型以上有矿床96处,中型123处,小型211处;矿床类型复杂多样,主要有岩浆型、斑岩型、伟晶岩型、接触交代（矽卡岩）型、热液型、海相火山岩型、变质型、沉积型（喷气-沉积型）、砂矿型、风化壳型、盐湖型、火山沉积型、构造-蚀变岩（造山）型、陆相火山岩型等14种类型;资源查明率低,其中,煤13.07%、铁16.65%、铜14.24%、铅15.35%、锌17.87%,岩金3.64%。由此可知,青海省主要优势与战略性矿产资源的进一步找矿空间和潜力是十分巨大的。

Characteristics of Mineral Resources in Qinghai Province

Mineral resources are abundant in Qinghai Province.132 kinds of ore types were found by 2007,and there were 107 kinds of ore types with proved reserves.There are 3 921 deposits in Qinghai Province,including 96 large deposits,123 middle deposits and 211 small deposits.The deposit types are complex and various which mainly include magmatic type,porphyry type,pegmatite type,contact metasomatic（skarn） type,hydrothermal type,marine volcanic rock type,metamorphic type,sedimentary（exhalative sedimentary） type,placer type,weathering crust type,salt lake type,volcanogenic sedimentary type,structural altered rock type,continental volcanic type,and so on.The investigation percentages are low.Investigation percentage of coal,iron,copper,lead,zinc,gold are 13.07%,16.65%,14.24%,15.35%,17.87%,and 3.64% respectively.In a word,there are huge prospecting space and potential of mineral resources in Qinghai Province.
