Geological Map of Spain. Scale 1:50.000 - Sheet 612 - ADEMUZ

The sheet 612 (ADEMUZ) of the National Geological Map (MAGNA), was made in 1978 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.西班牙国家地质图（National Geological Map，简称MAGNA）的第612幅（编号ADEMUZ）于1978年编制完成，2000年由西班牙地质调查局正式发布。该图件比例尺为1:5万，用于展示地表出露的物质（岩石与沉积物）类型、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年代范围的一种或多种岩性的集合体，以对应比例尺或既定分辨率在图面上进行表达。每个填图单元及各类地质构造，均通过专属符号系统在图上予以表示。将此类地质单元绘于地形底图之上，可提供一定的三维空间信息，该类信息可通过其他地质数据、地质剖面图、地层柱状图、钻孔等资料进行补充完善。本图图例为象形图示，用于展示不同填图单元间的空间关系，包括年代序列、叠置关系、几何联系、侧向相变等，同时还涵盖区域格架内的构造、水文地质及图幅地理位置等信息。 自1991年起，MAGNA系列国家地质图开始与同比例尺地貌图同步编制，二者不可分割。该套图件涵盖地表所有地质相关内容，并可提供关于地表形态的结构化精准信息。其编制基于地貌成因学与地貌年代学，采用源自地质图的表格/图例格式中的对应年代地层柱作为参照标准。地表的侵蚀与沉积地貌形态，通过专属符号、色彩样式以及能提供相关信息的地表沉积物或岩性地层单元进行个性化表达。 MAGNA系列的每一幅图幅均配有正式出版、编辑并以数字格式留存的说明报告。 数字信息以Coverage与Shapefile（ESRI）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说明。
