Geological Map of Spain. Scale 1:50.000 - Sheet 620 - ZARZA LA MAYOR

The sheet 620 (ZARZA LA MAYOR) of the National Geological Map (MAGNA), was made in 1987 and published in 1997 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（Geological Survey of Spain）于1987年编制、1997年发布了国家地质图（National Geological Map，MAGNA）的第620幅图幅——扎拉萨拉马约尔（ZARZA LA MAYOR）。该图比例尺为1:50000，旨在展示地表出露的物质（岩石与沉积物）的性质、空间分布，以及所绘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，将以对应比例尺或既定分辨率在图上进行表达。每个填图单元及各类地质构造，均通过专属符号体系在图上呈现。将这些单元绘于地形底图之上，可提供一定的三维信息，该信息可通过其他地质数据、地质剖面、地层剖面、钻探取样等予以补充完善。本图的图例为象形符号集，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、几何关系以及侧向相变等。图例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绑定编制，不可分割。该系列图件涵盖地表所有地质信息，并能系统、精准地呈现地表形态特征。其编制基于地貌成因与地貌年代学，参考地质图图例设计的表格中附有时地层柱，以此完成图件整合。侵蚀与沉积成因的地表形态，将通过专属符号、色彩样式，以及可提供相关信息的地表沉积物或岩性地层要素进行标识与表达。 MAGNA地质图系列的每一幅图幅均配有公开出版、经过编辑且采用数字格式的说明报告。 该数字信息以Coverage格式与Shapefile格式（ESRI）存储。另有一份指南对该数字信息的物理结构与编码规则进行说明。
