Webb12 maj 2024 · Sedimentary rocks form from two key processes: First, compaction squeezes material together. Second, cementing glues the squeezed material together. If you start with a big boulder and speed up time 10,000 years ahead, it would erode away into tiny, little sediments.
WebbPseudotachylite is a fault-zone rock which is black and glassy. It usually occurs as narrow dykes and veins and forms by frictional melting of the country rock. Mylonites are partially recrystallised rocks with a pronounced foliation that are produced by intense shearing during large-scale movements along faults and thrusts.
