Summary
| description | English: Figure.16.13. Map of the floodbasins sediments. The lithologies are mapped as set out in the legend, but in addition an interpretation of these lithologies is given by the following codes: Cs-crevasse splays; De-deltas; ch =channels. In this notation deltas (which are the result of crevasse sands building onto the floodplains) are a combination of two gradational or interfingering lithologies- medium grain-size sandstone and pebbly sandstone. Rose diagrams refer to the cross stratification dip directions O n-number of readings, L=vector magnitude a (which is inversely related to the standard deviation of spread of the data). The diagram total cross strata (overbank) refers to dip directions of the cross strata in the sandstone 0 sheets which have originated as sandstone crevasse splays i.e. De and Cs.
