中国地质调查局:新疆咸水泉幅 (K46E009024)1∶50000地质图数据库

新疆咸水泉幅（K46E009024）地处新疆哈密镜儿泉地区，大地构造位置位于北天山造山带康古尔断裂带东段，纵跨哈尔里克与觉罗塔格两个三级构造单元。通过构造-岩性的实体填图，建立了调查区地层格架，厘定出1个群级、3个组级正式填图单位，2个非正式填图单位；查明了调查区侵入体的岩石组合、接触关系及时空分布特征，获得了一批高精度的锆石U-Pb测年数据，厘定出三期主要的岩浆活动；基本查明了调查区内康古尔断裂带东段物质组成及变质变形特征，建立了调查区构造变形序列，并划分四期构造组合变形期次；梳理总结了区域内与石炭-二叠纪基性-超基性岩有关的岩浆型铜镍矿和与韧性剪切带有关的金矿的成矿规律和成矿条件。通过本次工作，为提高地质图的可利用程度提供了详实的资料基础，为探讨区域构造演化提供了新的依据。

Xinjiang Xianshuiquan Sheet (K46E009024) is located in the Jing'erquan area, Hami, Xinjiang Uygur Autonomous Region. Its tectonic position lies in the eastern section of the Kanggur Fault Zone of the North Tianshan Orogenic Belt, straddling two third-order tectonic units: the Harlik and Jueluotage domains. Through structural-lithologic field mapping, the stratigraphic framework of the survey area was established, with 1 group-level, 3 formation-level formal mapping units and 2 informal mapping units defined. The rock assemblages, contact relationships and spatio-temporal distribution characteristics of intrusions in the survey area were ascertained. A batch of high-precision zircon U-Pb dating data was obtained, and three main phases of magmatic activities were identified. The material composition, metamorphism and deformation features of the eastern segment of the Kanggur Fault Zone within the survey area were basically clarified; the tectonic deformation sequence of the survey area was constructed, and four phases of tectonic assemblage deformation were divided. The mineralization regularities and metallogenic conditions of magmatic Cu-Ni deposits related to Carboniferous-Permian mafic-ultramafic rocks and gold deposits associated with ductile shear zones in the region were sorted out and summarized. This work provides a detailed data foundation for improving the availability of geological maps and new evidence for exploring regional tectonic evolution.
