中国地质调查局: 内蒙古巴彦哈拉幅(K48E021017)1∶50 000地质图数据库

内蒙古巴彦哈拉幅(K48E021017) 1∶<number>50 000</number>地质图是在充分收集、综合分析已有地质资料基础上，依据《1∶ 50 000区域地质调查技术要求》(DD 2019—01)和行业统一标准及要求，应用数字填图技术，通过路线地质调查、实测剖面和大比例尺填图等多种手段相结合的方法完成的。在野外地质数据采集过程中，通过自查、互查及项目组抽查等方式对数据质量进行了监督，确保原始数据真实可靠。在填图数据采集完成的基础上，以中国地质调查局《数字地质图数据库标准》(DD 2006—06)为标准，建立了巴彦哈拉幅(K48E021017) 1∶<number>50 000</number>地质图数据库，详细表达了不同地质体的基本属性。本地质图数据库为MapGIS 格式，包括12个正式填图单位、6期岩浆岩事件、8期构造变形事件以及9个样品的锆石U–Pb年龄数据，数据量为210 MB。图幅采用造山带填图新理论和新方法，在图面表达中突出了多期构造形迹及其产状要素，全面反映了填图区自古元古代以来的多期构造变形样式及时代。同时开展了复杂构造区地质填图方法指南的编写，为系统构建构造地质填图新方法提供重要依据。该图幅为构造试点填图图幅，在2018年度全国区域地质调查图幅展评中荣获“特优图幅”奖。

The 1:<number>50 000</number> geological map of the Bayanhala sheet (K48E021017), Inner Mongolia, was compiled based on full collection and comprehensive analysis of existing geological data, in accordance with the Technical Requirements for 1:<number>50 000</number> Regional Geological Survey (DD 2019—01) and unified industry standards and requirements, using digital mapping technology and combining multiple methods such as route geological survey, measured sections and large-scale mapping. During the field geological data collection, the data quality was supervised through self-inspection, mutual inspection and spot checks by the project team to ensure the authenticity and reliability of the original data. Upon completion of the mapping data collection, the database for the 1:<number>50 000</number> geological map of the Bayanhala sheet (K48E021017) was established in accordance with the Digital Geological Map Database Standard (DD 2006—06) issued by the China Geological Survey, which elaborately expresses the basic attributes of different geological bodies. This geological map database is in MapGIS format, including 12 official mapping units, 6 stages of magmatic events, 8 stages of tectonic deformation events, and zircon U-Pb age data of 9 samples, with a total data volume of 210 MB. The map sheet adopted new theories and methods of orogenic belt mapping, highlighting multi-stage structural features and their occurrence parameters in the map expression, and comprehensively reflects the multi-stage tectonic deformation patterns and their ages since the Paleoproterozoic in the mapping area. Meanwhile, the compilation of the Geological Mapping Guide for Complex Tectonic Areas was carried out, providing an important basis for systematically establishing new methods of structural geological mapping. This map sheet is a pilot orogenic mapping sheet, and won the "Special Excellent Sheet" Award in the 2018 National Regional Geological Survey Sheet Exhibition and Evaluation.
