资源简介:
1∶50 000 geologic map of the Huangzhuang map-sheet (J50E004015), Tianjin was mapped  by  employing  the  Digital  Geological  Survey  System  (DGSS),  and  consequently  a database was built by fully collecting and making use of existing geological data, as well as following  industrial  specifications.  The  database  includes  four  datasets,  i.e.  a  basic  element, comprehensive  element,  object  element  and  independent  element,  in  total  23  different categories of data types, accumulating to a data size of 43.8 MB. Among them, there are 96 geological entities, 320 geological (boundaries) lines and 85 videos (photos), as well as nine samples of isotope dating, 10 boreholes and 13 sedimentary (volcanic) lithostratigraphic units. In  the  geologic  map,  the  genetic  type  of  the  superficial  deposit  landform  and  its  vertical geological structure, stratigraphic structure feature and lithofacies palaeogeographic evolution since  the  Late  Pliocene,  as  well  as  the  bedrock  geological  structure,  and  environmental engineering  geological  problems  were  all  summarized;  the  methodology  for  the  geological survey and innovative map presentation of the geologic map in the low coastal plain coverage area  was  explored  simultaneously,  which  all  play  an  exemplary  role  for  regional  geological survey in the coverage area. The database can provide detailed and basic geological data for geological environmental protection, natural resource management, in addition to hydrological, engineering  and  environmental  geological  surveying,  thus  supporting  a  sustainable development  of  an  important  national  economic  zone,  major  engineering  construction, geological and ecological environmental protection, and urban planning.
