SEDIMENTARY BASIN A sedimentary basin is a low area in the Earth’s crust, of tectonic origin, where sediments accumulate over a long period of time. These sediments are deposited by water, wind, or ice, and later become compacted and lithified into sedimentary rocks. FORMATION OF SEDIMENTARY BASINS Sedimentary basins form due to subsidence (sinking of the crust) caused by tectonic processes such as: ° Crustal stretching (rifting) ° Crustal loading (mountain building or volcanic loading) ° Therma

Rock of the week 3 – Sedimentary rocks – Mudstone First of all, what’s a sedimentary rock? A sedimentary rock is made up of sediments that have accumulated in a ‘basin’ over geological time to form a rock. These can be made up of clay, silt, sand, gravel, cobble or even boulder sized particles. What’s mudstone? Mudstone is a type of fine-grained sedimentary rock primarily composed of clay- and silt-sized particles. It can be dark, grey, dark grey, brown, green, purple and even red depending on t
