WebSince the Bouma paper of 1962 it has been demonstrated the turbidite deposit is a “member” of an evolutionary trend of vertically associated sediments that accumulate from debris flows, hyperconcentrated to concentrated density flows, and turbidity flows (Mulder & Alexander, 2001). As Parsons et al (2003) observe, “Gravity-driven motions produced … WebRip-up clasts are gravel-size pieces of clay or mud created when an erosive current flows over a bed of clay or mud and removes pieces of clayey sediment, and transports them some distance.Because clayey sediments can be quite cohesive, even when freshly deposited, large clasts of clayey sediment can be ripped up, transported and … how are preserved flowers made
