Lithological-petrographic map of Switzerland 1:200000

The Lithological-petrographic map of Switzerland 1:200,000 provides an overview of the subsurface classified according to lithological-petrographic criteria. The legend is designed in particular to facilitate the identification of the possible usages of the subsurface (e.g. extraction of mineral resources, construction projects). The point data overlay indicates the location of extraction and/or processing sites of mineral raw materials (Survey: 1963–1967). (Original name: Geotechnical map of Switzerland 1:200,000)1:200,000比例尺瑞士岩石岩相（Lithological-petrographic）地图，基于岩性岩相分类标准，全面呈现了瑞士地下地层的分布概况。该地图的图例专为辅助识别地下地层的潜在用途而设计，可应用于矿产资源开采、建筑工程作业等场景。叠加的点位数据标注了矿物原料开采及/或加工场地的具体位置，调查周期为1963–1967年。（原名称：1:200,000比例尺瑞士工程地质图）
