Formation
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
