Geological Map of Spain. Scale 1:50.000 - Sheet 169 - CASALARREINA

The sheet 169 (CASALARREINA) of the National Geological Map (MAGNA), was made in 1978 and published in 1993 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.西班牙国家地质图（MAGNA）的第169幅（CASALARREINA幅）于1978年编制完成，1993年由西班牙地质调查局正式发布，比例尺为1:50000。该地质图旨在展示地表出露物质（岩石与沉积物）的性质、空间分布特征，以及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体，以对应比例尺或既定分辨率在地图上予以表示。每个填图单元及各类地质构造均通过专属符号在地图上呈现。将这些单元绘于地形底图之上，可提供一定的三维空间信息，该信息可通过其他地质资料、地质剖面图、地层剖面、勘探孔等进一步补充完善。地图图例以象形图标形式呈现，用于说明不同填图单元的空间关系，涵盖年代学、叠置关系、几何关系、侧向相变等内容，同时还包含区域地质框架内的构造信息、水文地质信息及本幅图的地理位置。自1991年起，MAGNA系列地质图与同比例尺地貌图实现一体化编制。该系列地图涵盖了地表全部地质信息，可提供结构化且精准的地表形态信息。其编制基于地貌成因学与地貌年代学，参考地质图配套表格/图例中所载的对应年代地层柱进行规范整饰。地图通过专属符号、色彩样式以及地表沉积物或岩性地层要素，对侵蚀与沉积地貌形态进行个性化展示，并附带相关辅助信息。MAGNA系列的每一幅图均配有正式出版、编辑并以数字格式存储的说明报告。数字信息以Coverage和Shape格式（ESRI）存储，另有专属指南对数字信息的物理结构及其编码规则进行详细说明。
