Geological Map of Spain. Scale 1:50.000 - Sheet 587 - LAS MAJADAS

The sheet 587 (LAS MAJADAS) of the National Geological Map (MAGNA), was made in 1989 and published in 1994 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587幅图幅（LAS MAJADAS）于1989年编制完成，1994年由西班牙地质调查局（Geological Survey of Spain）正式发布，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，在图件中以对应比例尺或限定分辨率进行表示。每个填图单元及各类地质构造均通过专属符号在图上表达。将此类单元绘制于地形底图之上，可获取一定的三维空间信息，该类信息可辅以其他地质资料、地质剖面图、地层剖面、勘探孔数据等进一步完善。本图的图例为象形符号集，用以展示不同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，同时还涵盖了区域地质框架内的构造信息、水文地质信息以及本图幅的地质位置。 自1991年起，MAGNA系列国家地质图与同比例尺地貌图绑定编制。该图件整合了地表所有地质相关内容，可提供关于地表形态的结构化且精准的信息。其编制基于地貌成因与地貌年代学，并采用参考地质图的图例表格所附的对应年代地层柱来实现相关标注。图中通过专属符号、色彩模式以及可提供相关信息的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表达。 MAGNA系列的每一幅图幅均配有公开出版、编辑且采用数字格式的说明报告。 数字信息以ESRI的Coverage与Shapefile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详细说明。
