Geological Map of Spain. Scale 1:50.000 - Sheet 526 - SERRADILLA DEL ARROYO

The sheet 526 (SERRADILLA DEL ARROYO) of the National Geological Map (MAGNA), was made in 1990 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.西班牙地质调查局于1990年编制、1997年发布了国家地质图（MAGNA）的第526幅图幅（SERRADILLA DEL ARROYO幅），该图幅比例尺为1:50000。本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，以及图中所表示的各类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，在地图上以对应比例尺或限定分辨率进行表示。每个填图单元及各类地质构造，均通过专属符号在图上进行表达。将这些单元绘制于地形底图之上，可辅以其他地质资料、地质剖面图、地层剖面、取样点等补充三维空间信息。本图幅的图例为象形图标，用以说明不同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，同时还涵盖了区域地质框架内的构造、水文地质信息以及该图幅的地质位置。 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。该地貌图涵盖了地表全部地质相关内容，可提供关于地表形态的结构化且精准的信息。其编制以地貌成因与地貌年代学为基础，并采用依托地质图设计的表格/图例中收录的对应年代地层柱，将相关信息融入图件。地表侵蚀与沉积形态通过专属符号、色彩图案以及可提供相关信息的表层沉积物或岩性地层单元进行个体化表达。 MAGNA系列的每一幅图幅均配有公开出版、经过编辑且为数字格式的说明报告。 该数字信息以Coverage格式与ESRI Shape格式存储，另有一份指南对数字信息的物理存储结构及其编码规则进行说明。
