Also known as sandstone landform, it is a type of landform formed by sandstone development. Sandstone is a sedimentary rock composed mainly of sand-sized mineral particles or rock fragments. Common minerals include quartz, feldspar, and clay minerals. The difference of mineral composition, hardness and cementation degree will lead to different geomorphological forms. Quartz sandstone or siliceous cemented sandstone often forms relatively high mountains due to its strong weathering and erosion resistance, while coarse sandstone and feldspar sandstone that are not firmly cemented often form hills or basins. After a long period of erosion and weathering, the formation of a variety of strange landforms.
