Geological Map of Spain. Scale 1:50.000 - Sheet 63 - EIBAR

The sheet 63 (EIBAR) of the National Geological Map (MAGNA), was made in 1975 and published in 2005 by the Geological Survey of Spain. It is distributed at scale 50000. The geological map shows the nature of materials (rocks and sediments) that appear on the surface, their spatial distribution and geometric relationships between the different cartographic units represented. A geological mapping unit is the grouping of one or more lithologies with common age range, which is represented on the map at a scale or defined resolution. Each mapping unit, and the different geological structures, is represented on the map with a symbolism itself. The representation of these units on the topographic base map provides some three-dimensional information that is completed with other geological data and geological sections, stratigraphic profiles, polls, etc. The map legend is a pictogram representing the spatial relationship of the different mapping units (chronology, overlapping, geometric relationship, lateral facies changes, etc.). It also includes structural, hydrogeological and geological location of the sheet within the regional schemes. Since 1991, the Geological Map Series MAGNA is made inseparably with the geomorphological map on the same scale. This map incorporates everything on the surface geology and provides a structured and accurate information of the land forms. It is organized on the basis of morphogenesis and morphocronology incorporated the map using the corresponding chronostratigraphic column included in a table / legend inspired by the geological map. The forms, erosional and depositional, are represented on the map by individualized by symbols and patterns of color and surface deposits or lithological formations elements that provide information. For each sheet of the series MAGNA there is an explanatory report published, edited and in digital format. The digital information is stored in coverage and Shape format (ESRI). There is a guide that describes the physical structure of the digital information and its codification.西班牙地质调查局（Geological Survey of Spain）于1975年编制、2005年发布的国家地质图（National Geological Map, MAGNA）第63幅（编号EIBAR），比例尺为1:5万。该地质图展示了地表出露的物质（岩石与沉积物）的性质、空间分布，以及所绘各制图单元间的几何关系。地质填图单元是指具有共同年代范围的一种或多种岩性的集合，在地图上以对应比例尺或限定分辨率进行表达。每个填图单元及各类地质构造均通过专属符号在图上表示。将这些单元绘于地形底图之上，可提供一定的三维信息，并可结合其他地质数据、地质剖面图、地层剖面、钻孔试样等予以完善。该图的图例为象形符号，用以表示各填图单元的空间关系（包括年代序列、叠置关系、几何联系、侧向相变等），同时还包含区域框架内该图幅的构造、水文地质与地质位置信息。自1991年起，MAGNA系列地质图与同比例尺地貌图一体化编制。该图涵盖了地表所有地质信息，并提供了关于地表形态的结构化精准数据。其编制基于地貌成因与地貌年代学，采用借鉴地质图的表格/图例中所载的对应年代地层柱进行整合。地表的侵蚀与沉积形态通过专属符号、色彩模式以及能提供相关信息的表层沉积物或岩性地层单元要素予以分别表示。MAGNA系列的每一幅图幅均配有公开出版、经过编辑并以数字格式留存的说明报告。数字信息以ESRI的Coverage和Shape格式存储，另有一份指南对数字信息的物理结构及其编码规则进行说明。
