Geological Map of Spain. Scale 1:50.000 - Sheet 40 - JAIZQUIBEL

The sheet 40 (JAIZQUIBEL) of the National Geological Map (MAGNA), was made in 1974 and published in 2005 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1974年编制、2005年出版的《国家地质图（MAGNA）》第40幅（JAIZQUIBEL幅），比例尺为1:50000。该地质图展示了地表出露物质（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联。 地质填图单元（geological mapping unit）指具有共同年代范围的一种或多种岩性的集合，以对应比例尺或限定分辨率在图上表达。每个填图单元及各类地质构造，均采用专属符号系统在图中表示。将这些单元绘于地形底图之上，可获取一定的三维信息，该信息可通过其他地质资料、地质剖面、地层剖面、钻孔（polls）等加以补充完善。地图图例为象形图标，用于展示不同填图单元的空间关系（包括年代序列、叠置关系、几何关联、侧向相变等），同时还涵盖了该图幅在区域框架内的构造、水文地质及地理定位信息。 自1991年起，MAGNA系列国家地质图与同比例尺地貌图绑定编制，不可分割。该图整合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与地貌年代学，并依托借鉴地质图的表格/图例所附的相应年代地层柱，将相关信息纳入图件。地表侵蚀与沉积形态通过专属符号、色彩模式以及地表沉积物或岩性地层单元要素进行个性化表达，以传递相关信息。 MAGNA系列的每一幅图幅均配有公开出版、经过编辑的数字格式说明报告。 该数字信息以Coverage（coverage）数据格式与ESRI Shape格式存储，另有配套指南对数字信息的物理结构及其编码规则进行说明。
