Database of 1∶50 000 Mineral Geological Map of the Hongshi Map-sheet in Kalatage Copper (-Zinc) Deposit, Hami, Xinjiang

The database of 1∶50 000 mineral geological map of Hongshi Map-sheet(K46E009008) in Kalatage Copper (-Zinc) Deposit, Hami, Xinjiang (also referred to as theDatabase) was developed through field geology-specific mapping using the digital mappingsystem in accordance with the Technical Requirements of Solid Mineral Geological Survey(1∶50 000) (DD2019-02) and other standards and requirements in the geological industry.Meanwhile, the results of previous 1∶200 000 and 1∶50 000 regional geological surveyswere fully utilized, and indoor and outdoor mapping/compilation was also carried out duringdatabase building. In this database, the suites of the Daliugou Formation of Middle-UpperOrdovician Huangcaopo Group as well as Lower Silurian Hongliuxia and Kalatage formationswere reclassified. Moreover, the formation time of intrusive rocks in the map-sheet area wasdetermined as Silurian, Devonian, and Permian, and the evolutionary sequence of magmaticrocks was established. There are eight large, medium and small mineral deposits and oreoccurrences in the map-sheet area, the metallogenic epoch of which is concentrated in theSilurian and Carboniferous. The ore-hosted wall rocks are pyroclastic and subvolcanic rocks.The dominant mineral resources in this area are copper, zinc and gold, and their deposit typesare mainly VMS type and subvolcanic hydrothermal vein type, which are distributed in thesoutheastern zone of the map-sheet area. In addition to metallic minerals, there are bentonitedeposits with good prospecting potential. With a data size of about 15.1 MB, this databasecontains the data of five stratigraphic units and three stages of magmatic rocks. These datafully reflect the demonstration results of 1∶50 000 mineral geological survey of this mapsheetand provide references for the research and exploration of mineral resources in the surveyarea.

新疆哈密卡拉塔格铜（锌）矿床红石幅（K46E009008）1∶50000矿产地质图数据库（以下简称本数据库），系依据《固体矿产地质调查技术要求（1∶50000）》（DD2019-02）及地质行业其他相关标准规范，采用数字填图系统开展野外专项地质填图，充分利用前人1∶20万、1∶5万区域地质调查成果，结合室内外编图工作构建而成。本数据库对中晚奥陶世黄草坡群大柳沟组以及下志留统红柳峡组、卡拉塔格组进行了重新厘定；明确了图幅区内侵入岩的形成时代为志留纪、泥盆纪与二叠纪，并建立了岩浆岩演化序列。图幅区内共发育8处大、中、小型矿床及矿点，其成矿时代集中于志留纪与石炭纪，赋矿围岩为火山碎屑岩与次火山岩。区内优势矿产为铜、锌与金，矿床类型以VMS型（Volcanogenic Massive Sulfide）与次火山热液脉型为主，分布于图幅东南部区域。除金属矿产外，区内还发育具有良好找矿潜力的膨润土矿床。本数据库数据体量约15.1 MB，涵盖5个地层单元与3个期次的岩浆岩数据，全面反映了该图幅1∶50000矿产地质调查的成果，可为调查区矿产资源研究与勘探工作提供参考依据。
