Geological Map of Spain. Scale 1:50.000 - Sheet 299 - TOMIÑO

The sheet 299 (TOMIÑO) of the National Geological Map (MAGNA), was made in 1981 and published in 2007 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1981年编制、2007年发布的国家地质图（National Geological Map，简称MAGNA）第299幅（TOMIÑO幅），采用1:50000比例尺发行。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，以及各制图单元（cartographic units）间的几何关联。 地质填图单元（geological mapping unit）是指具有共同年龄范围的一种或多种岩性（lithologies）的集合体，在地图上以对应比例尺或既定分辨率进行表达。每一类填图单元及不同地质构造，均通过专属图示符号在图上呈现。将这些单元绘于地形底图（topographic base map）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（geological sections）、地层剖面（stratigraphic profiles）及钻孔试样（polls）等资料进行完善。本图的图例为象形图示，用以展示不同填图单元的空间关系（包括年代序列、叠置关系、几何关联、岩相横向变化等），同时还包含该图幅在区域格架中的构造、水文地质（hydrogeological）与地质位置信息。 自1991年起，MAGNA系列国家地质图与同比例尺地貌图（geomorphological map）一体化编制。该系列图件涵盖地表所有地质信息，并可提供结构化且精准的地表形态数据。其编制基于地貌成因（morphogenesis）与地貌年代学（morphocronology）框架，并参考地质图的格式，通过配套表格/图例中的对应年代地层柱（chronostratigraphic column）进行整合。图中各类侵蚀与沉积成因的地表形态，通过专属符号、色彩样式以及可提供信息的地表沉积物或岩性地层要素进行可视化表达。 MAGNA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。 该数字信息以覆盖型数据（coverage）与ESRI Shapefile格式（Shape format，ESRI）存储，同时配有专门指南，用以说明数字信息的物理结构与编码规则（codification）。
