WebLateral and vertical juxtaposition of matrix‐rich and matrix‐poor lithologies caused by particle settling in mixed mud–sand deep‐marine sediment suspensions. Sandy sedimentary rocks rich in detrital matrix (>10% silt/clay) have long been recognized in the ancient sedimentary record, and nowhere more commonly than in deep‐marine ... WebDepending on the concentration of solids and the tendency of particles to interact the following four types of settling may occur: 1. Type 1 – Discrete settling. 2. Type 2 – Flocculent settling. 3. Type 3 – Hindered or zone settling. 4. Type 4 …
