Geological Map of Spain. Scale 1:50.000 - Sheet 439 - AZUARA

The sheet 439 (AZUARA) of the National Geological Map (MAGNA), was made in 1989 and published in 2000 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.西班牙地质调查局于1989年编制、2000年发布了国家地质图（MAGNA）第439幅（阿苏阿拉，AZUARA）。该图采用1:5万比例尺发行，其内容展示了地表出露的物质（岩石与沉积物）类型、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形成年代范围的一种或多种岩性的集合体，以既定比例尺或分辨率在图面中表达。各填图单元及不同地质构造均通过专属图式符号在图上表示。将这些单元绘于地形底图之上，可提供一定的三维空间信息，该信息可辅以其他地质数据、地质剖面、地层剖面、钻孔等资料进行完善。地图图例以象形符号形式展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，同时还涵盖了该图幅在区域地质格架中的构造、水文地质与地质位置信息。 自1991年起，MAGNA国家地质图系列与同比例尺地貌图一体化编制，不可分割。该系列图涵盖了地表所有地质内容，并为地貌形态提供结构化且精准的信息。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/图例形式，配套对应的年代地层柱融入图件。侵蚀与沉积成因的地貌形态，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进行可视化表达，以此传递相关信息。 MAGNA系列的每一幅图幅均配有正式出版、经过编辑且为数字化格式的说明报告。 该数字化资料以数据覆盖层（coverage）与ESRI Shapefile格式存储，同时配有一份指南，用于说明数字化资料的物理结构与编码规范。
