What is the percentage of sandstone?It is a sandstone in geology
In the siltstone, the grain size of 0.0.01mm grain is more than 50%, which is dominated by quartz, and often contains a lot of muscovite. The content of potassium feldspar and acid plagioclase is less, and the cuttings are rarely seen
The sandstone in sedimentary rock distribution after clay rock. It is a size 2 ~ 0.1 mm range of detrital material composed of rocks.
