Geological Map of Spain. Scale 1:50.000 - Sheet 134 - POLIENTES

The sheet 134 (POLIENTES) of the National Geological Map (MAGNA), was made in 1994 and published in 2011 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1994年编制、2011年正式发布的国家地质图（MAGNA）第134号图幅（POLIENTES幅），比例尺为1:50000。该地质图展示了地表出露的物质（岩石与沉积物）的属性、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时代范围的一种或多种岩性的集合体，以特定比例尺或限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的图式符号在图中进行表示。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，该信息可通过其他地质数据、地质剖面、地层柱状图、勘探采样点等资料进行补充完善。 该图件的图例采用象形图示方式，用以展示各类填图单元的空间关系，包括时代序列、叠置关系、几何联系、侧向相变等；同时涵盖了区域地质格架下的该图幅的构造、水文地质及地质位置信息。 自1991年起，MAGNA国家地质图系列与同比例尺地貌图绑定编制，二者不可分割。该系列图件涵盖了所有地表地质信息，并可提供结构化且精准的地表形态信息。其编制以地貌成因及地貌年代学为组织依据，通过参考借鉴地质图图例所配套的年代地层柱状表（以表格/图例形式呈现）实现内容整合。各类侵蚀与沉积地貌形态均通过专属符号、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达。 针对MAGNA系列的每一幅图幅，均配有经过正式出版、编辑的数字化说明报告。该系列的数字化信息以Coverage与Shape格式（ESRI）进行存储，同时配套有一份指南，用以说明该数字化信息的物理存储结构及其编码规则。
