WebWhat is the definition of graded bedding? Particles become progressively heavier. What is the definition of clastic? Clastic is formed from abundant deposits of loose sediments on Earth's surface. Limestone? a sedimentary rock consisting mainly of calcium that was deposited by the remains of marine animals. WebThe cross-beds reflect the steep faces of ripples and dunes. These steep faces tilt down-current and thus indicate current flow direction. Cross-beds are commonly curved at the base; this gives a handy way of determining …

WebSeveral sedimentary structures that are commonly found in braided rivers are trough cross-bedding, upper planar, and ripple laminations. 1. Trough cross-bedding in channels. This occurs due to the migration of irregular dunes. 2. The coarsest sediment can be lower flat laminated if flow speeds are not fast enough to form coarse grained dunes. WebCross-bedding is a very important sedimentary structure to recognize because it can provide information on the direction of current flows and, when analyzed in detail, on other features like the rate of flow and the …
