This layer shows the shallow appearance (up to 50 m below ground level) of the relevant mineral geological unit. This layer is a processing of the grid layer of the top of this geological unit, which determines G3Dv3.1 (Deckers et al., 2019) for the geological 3D model. The quality of minerals may vary within a geological unit. The shallow appearance in a given place is therefore not a guarantee that a good quality of the mineral in question is found on that site.本图层展示了相关矿产地质单元的浅层地表形态（地下深度不超过50米）。本图层为该地质单元顶部网格图层的处理产物，符合地质三维模型所采用的G3Dv3.1规范（Deckers等，2019）。同一地质单元内部的矿产品质可能存在差异，因此某一特定地点的浅层地表形态，并不能保证该点位赋存高品质的目标矿产。
