Abstract
Effect of Change of Wave Size on the Size and Shape of Ripple Marks
O. F. Evans
ABSTRACT
Although ripple marks are somewhat resistant to the effect of changes in the size of the generating waves, yet when waves decrease in size there also usually occurs a change in the size and shape of the underlying ripples. Some new forms of ripples are described. One of these has rounded crests and angular troughs and is the reverse of the common symmetrical wave formed ripple. Another type consists of a series of alternately wide and narrow ripple marks. Both forms occur in relatively narrow belts near shore. Conditions are indicated under which fossil ripple marks can be used as a help in determining sequence in sedimentary beds.
