Geological Map of Spain. Scale 1:50.000 - Sheet 1047 - SANLÚCAR DE BARRAMEDA

The sheet 1047 (SANLÚCAR DE BARRAMEDA) of the National Geological Map (MAGNA), was made in 1988 and published in 2009 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1988年编制、2009年发布了国家地质图（National Geological Map，简称MAGNA）的第1047号图幅（桑卢卡尔-德巴拉梅达，SANLÚCAR DE BARRAMEDA）。该图件采用1:5万比例尺发行，其展示了地表出露的物质（岩石与沉积物）类型、空间分布特征，以及所绘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体，以对应比例尺或既定分辨率在图件中予以表达。每一个填图单元以及各类地质构造，均通过专属符号在图上进行表征。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，此类信息可通过其他地质数据、地质剖面图、地层剖面、钻孔等资料进行补充完善。本图的图例为象形符号集，用以阐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，同时还涵盖了该图幅在区域框架内的构造、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实现一体化编制，不可分割。该套图件涵盖地表地质的全部内容，可系统且精准地提供地表形态信息。其编制以地貌成因学与地貌年代学为基础，采用源自地质图图例的表格中所附的对应年代地层柱，将相关信息纳入图件。地表的侵蚀与沉积地貌形态，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个性化表征。 MAGNA国家地质图系列的每一幅图幅均配有经编辑发布的数字化说明报告。 该数字化数据以ESRI的Coverage格式与Shape格式存储，同时配有一份指南，用以说明数字化数据的物理结构及其编码规则。
