Geological Map of Spain. Scale 1:50.000 - Sheet 220 - LA JUNQUERA

The sheet 220 (LA JUNQUERA) of the National Geological Map (MAGNA), was made in 1994 and published in 2008 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1994年编制、2008年发布的西班牙国家地质图（National Geological Map, MAGNA）第220幅（拉洪克拉LA JUNQUERA），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）的性质、空间分布特征，以及不同制图单元间的几何关系。 地质填图单元（geological mapping unit）是指具有共同年代范围的一种或多种岩性的集合体，以对应比例尺或规定分辨率在图上进行表示。每个填图单元以及各类地质构造，均通过专属符号体系在图中呈现。将这些单元叠加于地形底图（topographic base map）之上，可获得一定的三维空间信息，该信息可辅以其他地质资料、地质剖面图、地层剖面、钻孔（polls）数据等进一步完善。图面图例为象形图示，用于说明不同填图单元的空间关系（包括年代序、叠置关系、几何联系、侧向相变化等），同时还涵盖了区域格架内的构造、水文地质信息以及该幅图的地质位置。 自1991年起，MAGNA系列地质图与同比例尺地貌图同步编制，二者不可分割。该图件整合了地表所有地质相关内容，并提供了关于地表形态的结构化精准信息。其编制基于地貌成因与地貌年代学，采用由地质图图例衍生而来的表格/图例中的年代地层柱作为参照。图中通过专属符号、色彩样式以及地表沉积物或岩性地层单元要素，对侵蚀与沉积地貌形态进行个性化表征。 针对MAGNA系列的每一幅图件，均配有公开出版、经过编辑且为数字化格式的说明报告。 该数字化信息以覆盖型数据集（coverage）和ESRI Shape格式（Shape format (ESRI)）存储。另有一份指南对数字化信息的物理结构及其编码规则进行说明。
