| 摘 要： | 柴达木盆地是我国主要的盐类存储矿带，有己发现并探明储量和资源量的矿产12种，氯化钾、氯化镁和氯化锂等资源储量居全国首位，同时不断有许多新地域、新层位、新类型、新深度的矿床/矿体被发现，显示出柴达木盆地具大的找矿潜力。本文在全国成矿单元划分基础上，利用最新研究成果，以柴达木盆地新生代地质构造环境为基础，突出盐类矿产原则，综合分析赋盐矿产的岩相、古气候、水文条件和盐类成矿规律及成矿特征等，全面系统地划分了柴达木盆地盐类矿产成矿单元。本文提出柴达木盆地Ⅰ级成矿域隶属秦祁昆成矿域，Ⅱ级成矿省属昆仑成矿省，Ⅲ级成矿区带为柴达木盆地锂-硼-钾-钠-镁-盐类-石油-天然气-芒硝-天然碱成矿带；进一步划分为柴北缘硼-锂-钾盐成矿亚带、中央钾-石盐-镁-锂-天青石-芒硝成矿亚带、昆北硼-钾-石盐-芒硝成矿亚带、察尔汗钾-石盐-镁-锂-硼-天然碱成矿亚带、德令哈石盐-天然碱成矿亚带5个Ⅳ级成矿亚带以及21个Ⅴ级矿集区。

| Abstract: | Qaidam basin is
the main salt storage ore belt in China. At present, there have discovered 12
kinds of minerals with proven reserves and resources, among which the reserves
of potassium chloride, magnesium chloride and lithium chloride rank first in
China. At the same time, many deposits/ore bodies in new regions, new horizons,
new types and new depths have been discovered, showing that Qaidam basin has
great prospecting potential. Based on the division of national metallogenic
units, using the latest research results, on the basis of Qaidam basin in the
Cenozoic geological tectonic environment, highlighting the principle of salt
minerals, this paper comprehensively analyzes the lithofacies, paleoclimate,
hydrological conditions, salt metallogenic laws and metallogenic
characteristics of salt bearing minerals, and systematically divides the salt
metallogenic units of Qaidam basin. In this paper, it is proposed that the
Grade Ⅰ metallogenic domain belongs to the Qin-Qi-Kun metallogenic domain,
the Grade Ⅱ metallogenic province belongs to the Kunlun
metallogenic province, and the Grade Ⅲ metallogenic
belt is the Li-B-K-Na-Mg-salt-oil-gas-glauber’s
salt-natural alkali metallogenic belt in the Qaidam basin; It is further
divided into five Grade Ⅳ metallogenic subzones: The
boron-lithium-potassium mineralization subzone in the northern margin of Qaidam
basin, the central potassium-halite-magnesium-lithium-celestite-mirabilite
metallogenic subzone, the boron-potassium-halite-mirabilite mineralization
subzone in the north of Kunlun, the Chaerhan
potassium-halite-magnesium-lithium-boron-trona metallogenic subzone, and the
Delingha halite-trona metallogenic subzone; and 21 Grade V ore concentration
areas. |
