摘要:
内蒙古居力格台幅 (K48E017019)1∶50 000地质图是根据《区域地质调查技术要求(1∶50 000)》(DD 2006-XX)和行业统一标准及要求，充分利用1∶200 000区域地质、1∶50 000矿产调查资料，结合Spot、ETM、Aster等多种遥感影像，以造山带理论指导填图的重要成果图件之一。本次运用复杂构造区的地质填图方法，创新性地在地质图上表达了多期构造形迹及其产状要素；图件全面反映了狼山地区乌拉特后旗一带不同侵入体的空间展布和侵入岩的岩浆序列，以及渣尔泰山群变质沉积岩的韵律和变形特征、沉积时代和沉积环境；进一步明确了霍各乞大型铜矿的赋矿围岩为阿古鲁沟组二段炭质–钙质板岩，矿床总体位于该地层中片理褶皱形成的转折端部位。图幅数据库的数据内容包含有3个非正式填图单位，12个正式填图单位、3期岩浆事件和3期构造变形，以及120个岩石化学分析数据，13个样品的锆石U-Pb年龄数据，数据量为106 MB。数据库成果为1∶50 000造山带地质调查示范性成果，对造山带填图的图面表达具有引领作用，可为后续地质基础研究及找矿提供重要的基础资料支撑。
Abstract:The 1∶50 000 Geological Map of the Juligetai Map-sheet (K48E017019), Inner Mongolia was compiled according to the ‘Technical Requirements for Regional Geological Surveys (1∶50 000)’ (DD 2006-XX) and other uniform standards and requirements. It also makes full use of the data from the 1∶200 000 regional geological survey and 1∶50 000 mineral resource survey, and adopts various remote sensing imagery systems including Spot, ETM and Aster. It is an important mapping achievement guided by the orogenic belt theory. In the current project, a geological mapping method for complex tectonic areas was used to creatively express the structural features in multiple stages and their attitude features in geological maps. The map comprehensively reflects the spatial distribution of different intrusive bodies and magmatic sequence of intrusive rocks in the Wulatehou Banner in Langshan area, as well as the rhythm and deformation characteristics, sedimentary age and sedimentary environment of metamorphic sedimentary rocks of the Zhaertaishan Group. The wall-rocks of the Huogeqi Copper Deposit was further identified as carbonaceous-calcareous slates of the Agulugou Formation’s second member. The deposit is mostly located at the hinge zone of the schistose fold in the stratum. The map database includes 3 informal mapping units, 12 official mapping units, 3 periods of magmatic events and 3 tectonic deformations, in addition to 120 pieces of petrochemical analysis data and zircon U–Pb age data of 13 samples, with a data size of 106 MB. The database represents an exemplary result of the 1∶50 000 orogenic belt geological survey. It plays a leading role in orogenic belt mapping and is able to support subsequent basic geological research and prospecting by providing essential basic data.
