Geological Map of Spain. Scale 1:50.000 - Sheet 340 - MANGANESES DE LA LAMPREANA

The sheet 340 (MANGANESES DE LA LAMPREANA) of the National Geological Map (MAGNA), was made in 1981 and published in 2007 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，National Geological Map）第340幅（图名：MANGANESES DE LA LAMPREANA）由西班牙地质调查局（Geological Survey of Spain）于1981年编制，2007年正式发布。该图件按1:50000比例尺发行。本地质图展示了地表出露的物质（岩石与沉积物）的属性、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组合，以对应比例尺或既定分辨率在地图上进行表达。每个填图单元及各类地质构造均通过专属符号系统在图中呈现。将此类填图单元绘制于地形底图之上，可获取一定的三维空间信息，该类信息可通过其他地质数据、地质剖面、地层剖面、取样点等资料进行补充完善。本图的图例为一套象形符号体系，用于表征不同填图单元的空间关系，涵盖年代序列、叠置关系、几何关联及侧向相变化等内容。图例同时包含区域地质框架内的构造、水文地质信息以及该图幅的地质定位信息。 自1991年起，MAGNA系列国家地质图与同比例尺地貌图实现一体化编制。该系列图件涵盖地表全部地质信息，可系统且精准地展现地表地貌形态。其编制以地貌成因与地貌年代学为基础，参考地质图配套表格/图例中的年代地层柱，将相关信息整合至图件中。侵蚀与沉积成因的地貌形态通过专属符号、色彩样式，以及可提供有效信息的地表沉积物或岩性地层单元要素在图中得以表达。 针对MAGNA系列的每一幅图件，均配有正式出版、编辑完成的数字化说明报告。 该数字化资料以Coverage和Shape format（ESRI）格式存储。另有配套指南对该数字化资料的物理结构与编码规则进行详细说明。
