    • 摘要: 河北省古冶幅(J50E002018)、唐山幅(J50E003017)、范各庄煤矿幅(J50E003018)1∶50 000地质图空间数据库是在充分收集以往地质资料的基础上, 在唐山市区及周边开展古冶幅、唐山幅、范各庄煤矿幅1∶50 000区域地质调查工作, 编制相应图幅的1∶50 000地质图, 并依据《数字地质图空间数据库标准》(DD 2006–06)建立而成。通过遥感解译、野外数字填图、第四系钻探、人工浅钻及浅层地震剖面等手段采集数据。数据库包括基本要素类、综合要素类、对象类及独立要素类。其中基本要素类共包括651个地质体面实体(第四系、沉积岩、变质岩、侵入岩等面实体)数据、1428个地质界线数据、194个产状数据、562个照片数据、70个年龄(锆石U–Pb测年、14C、OSL测年)数据、5个第四系钻孔数据; 综合要素类数据主要为标准图框(内图框); 对象类包括57个沉积岩岩石地层单位(包括第四系)数据、2个侵入岩岩石年代单位数据、断层、脉岩、面状水域、图幅基本信息数据; 独立要素类主要为角图, 未添加属性。本数据库建立过程始终坚持完善的质量控制体系, 确保了数据的真实性、可靠性和准确性, 为相应区域的经济可持续发展、城市规划建设、生态环境保护和重大工程施工等提供基础地质支撑。

       

      Abstract: In accordance with the ‘Standard of Digital Geological Map Spatial Database’ (DD 2006–06), the 1∶50 000 Geological Map Spatial Database of Guye Map-sheet (J50E002018), Tangshan Map-sheet (J50E003017) and Fangezhuangmeikuang Map-sheet (J50E003018), Hebei Province was completed by fully collecting previous geological data, and conducting 1∶50 000 regional geological survey of Guye Map-sheet, Tangshan Map-sheet and Fangezhuangmeikuang Map-sheet in and around Tangshan City, with 1∶50 000 geological maps compiled. Data was collected by means of remote sensing interpretation, field digital mapping, Quaternary drilling, manual shallow drilling and shallow seismic profiles. The database includes four datasets, i.e. basic element, comprehensive element, object and independent element, of which the basic element dataset includes 651 pieces of geopolygons (Quaternary, sedimentary rocks, metamorphic rocks, intrusive rocks and other area entities), 1428 geological boundaries, 194 attitudes, 562 photos, 70 data for dating (zircon U–Pb, 14C and OSL dating), and five data pertaining to Quaternary drill holes; the comprehensive element dataset consists primarily of standard frame (internal map frame); the object dataset includes 57 data on sedimentary lithostratigraphic units (including the Quaternary), two data applied to intrusive lithochronological units, faults, dikes, water region and map-sheet basic information; the independent element dataset comprises primarily angular maps, with no attributes added. The database was constructed under a stringent quality control system throughout the entire process, which ensures the authenticity, reliability and accuracy of data, thus providing reliable geological support for sustainable economic development, urban planning, construction, ecological preservation and major engineering projects in corresponding regions.
