This layer shows the shallow occurrence (up to 50 m below ground level) of the relevant mineral-containing geological unit. This layer is an operation of the raster layer of the top of this geological unit, determined for the geological 3D model G3Dv3.1 (Deckers et al., 2019). The quality of minerals can vary within a geological unit. The shallow appearance in a particular place is therefore not a guarantee that a good quality of the mineral in question will be found in that place.本图层展示了目标含矿地质单元的浅层赋存状态（地下埋深不超过50米）。本图层系针对地质三维模型G3Dv3.1（Deckers等，2019），由该地质单元顶面栅格图层经运算生成的产物。同一地质单元内的矿石品质存在差异，因此，某一特定区域的浅层赋存状态，无法确保在该区域内可采获品质优良的目标矿物。
