It is mainly because of their symmetrical nature that the wave direction could not
be ascertained, nevertheless they indicate a particular wave velocity below and
above which oscillation ripple marks are not formed. As already stated, oscillation

However, this does not indicate prevalence of a totally arid climate because salt
can crystallize "in shallow intermittently flooded areas even in regions of
abundant rain fall" (Pettijohn, 1957, p. 601). However, in the case of the

Chlorite flakes variously indicate oxidation effects and at places are brownish-red
in colour. Biotite, muscovite, and chlorite are all oriented in the same direction (
parallel to bedding), and are inrerlamiuated with quartz grains. These flaky ...
