Compaction in geology is when sand, dirt, clay, and/or small rocks are pressed together over time so that ... SpletThis early shortening is attributed to the Barramundi Orogeny. The Barramundi compressional event was followed by extension, leading to basin formation and deposition of rocks of the Leichhardt Superbasin. At ~1620 Ma an early phase of thrusting and folding resulting from north–south compression took place and was followed between
