可可西里地区矿产资源信息（1966-1990）

受自然条件的限制，历史上青海省可可西里地区的地质资料相对较少，矿产资源的研究程度也很低。1986年以来，青藏公路两侧相继开展了1：20万区调，先后发现了白垩系含铜砂岩层、渐新统石膏和岩盐层、中新统的银、锌菱铁矿和油页岩层、现代湖泊中的锂、钾卤水矿化，以及碱性侵入岩的金矿化等矿点和矿化信息。80年代中期淘金浪潮由东昆仑山移到可可西里北缘，自发的民采高潮历时数年，至今仍未停歇，开辟了由五道梁向西到太阳湖、芒崖以至新疆的名声显赫的“黄金大道”，五雪峰-马兰山一带到处都有采挖场地。本次综合科学考察尽可能地进行了矿产信息的搜集和成矿条件的研究。考察中除进一步证实碱性岩体含金之外，还发现了渐新统菱铁矿层位、岩脉型原生金矿转石和相应的岩脉金矿化，以及内生锡-多金属矿化等一批重要的成矿信息和找矿靶区、点。已知的成矿事实说明本区矿产资源前景很好，并且独具特色。
主要根据近年青海省地矿系统区调所获成果和本次综合科学考察的结果，综合对比研究之后选出了30个矿产资源点(含小型矿床、矿点和矿化信息)列表，以求简明地反映本区已知的矿产资源概况。表中所列矿产点亦可参考《青海可可西里及邻区地质图》上。
摸清该区矿产资源数量、质量、结构和空间分布情况，为该区资源安全和经济安全提供了保障，意义重大。数据来源于前人的资料、此次科考的野外考察和室内整理。

Restricted by natural conditions, the geological data and research degree of mineral resources in the Hoh Xil region of Qinghai Province were relatively scarce historically.

Since 1986, 1:200000 regional geological surveys have been carried out successively on both sides of the Qinghai-Tibet Highway. A series of mineral occurrences and mineralization information have been discovered, including Cretaceous copper-bearing sandstone beds, Oligocene gypsum and rock salt beds, Miocene silver-zinc siderite and oil shale beds, lithium-potassium brine mineralization in modern lakes, and gold mineralization in alkaline intrusive rocks.

In the mid-1980s, the gold prospecting wave moved from the Eastern Kunlun Mountains to the northern margin of Hoh Xil. A spontaneous upsurge of private mining lasted for several years and continues to this day, opening up the well-known "Golden Road" extending westward from Wudaoliang to Taiyang Lake, Mangya and even Xinjiang, with mining sites scattered across the Wuxuefeng-Malanshan area.

This comprehensive scientific expedition collected mineral information and studied metallogenic conditions as comprehensively as possible. During the expedition, in addition to further confirming gold-bearing alkaline rock bodies, a number of important metallogenic information and prospecting targets/sites were discovered, including Oligocene siderite horizons, vein-type primary gold ore boulders and corresponding vein gold mineralization, as well as endogenic tin-polymetallic mineralization.

Known metallogenic facts indicate that the mineral resources in this region have excellent prospects and unique characteristics.

Mainly based on the achievements of regional geological surveys from the Qinghai Provincial Geological and Mineral Exploration System in recent years and the results of this comprehensive scientific expedition, a list of 30 mineral resource sites (including small deposits, mineral occurrences and mineralization information) was selected after comprehensive comparative research, in order to briefly reflect the general situation of known mineral resources in this region. The mineral sites listed in the table can also be referenced on the "Geological Map of Qinghai Hoh Xil and Its Adjacent Areas".

Ascertaining the quantity, quality, structure and spatial distribution of mineral resources in this region provides a guarantee for regional resource and economic security, which is of great significance. The data are derived from previous literature, field investigations and indoor collation of this scientific expedition.
