Geological Map of Spain Scale 1:200.000 (2nd series)

This Map depicts the materials or rocks that appear on the surface of the sheet, their spatial distribution, nature and geometric relationships. The cartographic units are chronostratigraphic groupings, with common lithology and age formed by strata which are called formations, groups or members; other non-stratified ones such as granites are represented. The structural relationships between them are expressed by symbols, which gives the map a three-dimensional character completed by additional geological profiles. These are the graphic expression of the deep geometrical arrangement of the units shown on the geological map. Applied information such as water points, mineral deposits and indications, presence of fossils and other elements of point representation are added by means of symbology. The printed sheets include geological sections, columns of the main zones or units and various diagrams (regional geological and tectonic diagrams, both at a scale of 1:1,000,000). The nominal scale of the series is 1:200,000, but in the island territories it has been produced at a scale of 1:100,000. The digital information, geological map 1:200,000, chronolithostratigraphic legend and legend of geological symbols, is stored in coverage format (ESRI). There is a guide reflecting its organisation and codification. The IGME is responsible for the execution of this series of cartography, which it finances with its own resources. The creation of this cartography is based on the compilation of existing information, mainly MAGA cartography at a scale of 1:50,000, doctoral theses and other research work.本地图描绘了图幅地表出露的物质或岩石、其空间分布、属性与几何关系。制图单元为年代地层组合：由具有统一岩性与形成时代的地层构成的单元可称为组、群或段；其余非层状岩体（如花岗岩）亦一并标注。各单元间的构造关系通过符号表达，辅以附加地质剖面以赋予地图立体性——此类剖面直观展示了地质图上各单元的深部几何展布。此外，通过符号系统还添加了各类应用要素，包括水文点位、矿床与矿化点、化石产出点及其他点位类要素。印刷图幅包含地质剖面图、主要区域/单元的地层柱状图，以及各类图件（如1:100万比例尺的区域地质与构造图）。 本系列图的标称比例尺为1:200,000，但在岛屿区域采用1:100,000比例尺制作。 数字化信息包含1:200,000比例尺地质图、年代岩石地层图例及地质符号图例，以Coverage格式（ESRI）存储，并配有反映其编制体系与编码规则的使用指南。 IGME负责本系列制图的编制工作，资金来源于其自有经费。 本系列制图的编制基于现有资料汇编，主要包括1:50,000比例尺的MAGA填图数据、博士学位论文及其他研究成果。
