Paleocurrents indicators and its analysis ~ …

Flute casts are local scours in the substrata generated by vortices within a flow. As the turbulent vortex forms it is carried along by the flow and lifted up, away from the basal surface to leave an asymmetric mark on the floor of the flow, with the steep edge on the upstream side. The direction along the axis of the scour away from the steep edge is measured. Flow axis indicators are ...

Most interpretations on the origin of sedimentary rocks are based on the calculation of a few distribution moments of grain- size measurements. All information about the sedimentary environment contained in the granulometric spectrum is not completely used. Utilization of all information is possible only with a model describing grain-size distribution in the formation mechanism. The problem of ...

The Lebediev's table [4] gives the critical velocity of current below which particles fall according to their size and the depth of water. Thus, it is possible, from the sizes of particles in a sedimentary rock formation, to determine the velocities of the paleocurrents. These velocities, integrated into the formula of sedimentary mechanics, give the sedimentary transport capacity by units ...

6.1 Clastic Sedimentary Rocks A clast is a fragment of rock or mineral, ranging in size from less than a micron [1] (too small to see) to as big as an apartment block. Various types of clasts are shown in Figure 5.12 and in Exercise 5.3. The smaller ones tend to be composed of a single mineral crystal, and the larger ones are typically composed of pieces of rock.
