| Summary: | This is a compacted sandstone from Crocker Formation in Sabah. The sample has very fine to fine grains of minerals, mostly accommodated by higher concentration of quartz.
The term compacted is used to show that the rock had underwent burial at certain depth in the Earth, resulting into removal of the air spaces (porosity) and increasing the density of the rock. In this display, mud drapes or mud clasts are clearly visible (seen as the elongated dark grey traces, and most obvious in the left side of the display. The mud drapes indicates the rock was deposited in a tidal environment, which is part of the marine shore that was submerged and then was exposed again, due to the rise and falls of the sea. Commonly sandstone is widely used for construction industry. |
