Geological Map of Spain. Scale 1:50.000 - Sheet 739 - LA ALAMEDA DE CERVERA

The sheet 739 (LA ALAMEDA DE CERVERA) of the National Geological Map (MAGNA), was made in 2010 and published in 1995 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.西班牙地质调查局完成于2010年、并于1995年出版的国家地质图（MAGNA）第739幅图件（LA ALAMEDA DE CERVERA），比例尺为1:50000。该地质图旨在展示地表出露的物质（岩石与沉积物）类型、空间分布特征，以及各制图单元间的几何关联。 地质填图单元指具有共同时代范围的一种或多种岩性的组合，将按照既定比例尺或分辨率在图件中予以表示。每个填图单元与各类地质构造，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，可提供一定的三维空间信息，该信息可辅以其他地质数据、地质剖面图、地层剖面以及勘探采样点位等内容进行完善。本图的图例为象形图示，用于展示不同填图单元间的空间关联，包括时序关系、叠置关系、几何关联以及侧向相变等。图例同时涵盖了区域地质框架内该图幅的构造、水文地质与地质位置信息。 自1991年起，MAGNA国家地质图系列开始与同比例尺地貌图一体化编制。该系列图件涵盖地表所有地质要素，可系统且精准地呈现地表形态特征。其编制以地貌成因学与地貌年代学为依据，并参考地质图的图例格式，通过表格/图例中附载的对应年代地层柱实现内容整合。图中的侵蚀与堆积地貌形态，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单元要素进行个性化表征。 MAGNA系列的每一幅图幅均配有正式出版、经过编辑且采用数字格式的说明报告。 该数据集的数字信息以Coverage格式与ESRI Shapefile格式存储。另有一份指南对该数字信息的物理结构及其编码规则进行说明。
