Geological Map of Spain. Scale 1:50.000 - Sheet 521 - BECEITE

The sheet 521 (BECEITE) of the National Geological Map (MAGNA), was made in 1985 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（National Geological Map，简称MAGNA）第521号图幅（BECEITE幅）由西班牙地质调查局（Geological Survey of Spain）于1985年编制完成，2007年正式发布，比例尺为1:50000。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，以及不同制图单元间的几何关系。 地质填图单元是指具有共同时代范围的一种或多种岩性的集合体，以对应比例尺或限定分辨率在图面中表示。每个填图单元及各类地质构造均配有专属符号系统进行图面表达。将上述单元绘于地形底图之上，可获取部分三维地理信息，此类信息可通过其他地质资料、地质剖面图、地层柱状图、勘探钻孔等进行补充完善。本图的图例为象形图标，用于表征不同填图单元的空间关系，包括年代序列、叠置关系、几何关联、侧向岩相变化等；同时还包含区域格网内的构造、水文地质及该图幅的地理位置信息。 自1991年起，MAGNA国家地质图系列开始与同比例尺地貌图同步编制，二者不可分割。该图件涵盖地表全部地质内容，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，并融入了以地质图图例为参考编制的年代地层柱状附表。图中通过专属符号、色彩样式以及地表沉积物或岩性地层单元要素，对侵蚀与沉积成因的各类地貌形态进行个体化表达。 MAGNA系列的每一幅图幅均配有公开出版、经编辑整理的数字化说明报告。 数字化信息以矢量覆盖数据集（coverage）与ESRI Shapefile格式存储。现有一份指南对该数字化信息的物理结构与编码规则进行了详细说明。
