Abstract
A Textural Study of Marine Sediments in a Portion of Cardigan Bay (Wales)
Anthony S. G. Jones
ABSTRACT
Textural analyses of 120 bay samples and 15 beach samples from a portion of southern Cardigan Bay reveal that a large part of the area is floored by well sorted, medium to fine sands. Coarse gravel sediments are confined to a bathymetric high in the northern part of the area and to a narrow coastal strip. Finer gravels occur on the western boundary. The finest, muddy, sediments are to be found in the region of the Trawling Ground, a bathymetric low. It is concluded that the sign of the skewness is sensitive to the environment. There appears to be a general interrelationship between the form of the bathymetry and the textural parameters. The grain size frequency distributions may best be explained in terms of Spencer's (1963) three fundamental populations and the mixing of two or more f these populations.
