WebSoils derived from limestone are generally more fertile than those derived from sandstone, because limestone contains more of the chemical elements that make important plant nutrients. Highly weathered soils can also be less fertile than moderately weathered soils because high levels of weathering can leach (take away) all the soil nutrients ... WebMay 6, 2024 · Sandstones with more than 15% silt and clay are called wackes (e.g., quartz wacke, lithic wacke). It’s worth taking a closer look at the different types of sandstone because sandstone is a common and important sedimentary rock. Typical sandstone compositions are shown in Figure 6.1. 6.
