Clays (Inventory)/Massive Bank
From LagWiki
The Massive Bank field of the Clays section should be used to record stations that exhibit a massive amount of clay in a single location.
In the Guadalupes, such massive banks of clay are usually red in color; but, they could be a variety of colors. Massive clay banks differ from corrosion residues. Where corrosion residues were concentrated when the limestone was dissolved and left them behind, massive clay banks are original concentrations in the bedrock. Similarly [[Clays (Inventory)/Residual red Clay|residual red clays are concentrated from dissolution and not original masses. This distinction may be difficult to discern accurately.
Massive clay banks are most often found associated with the backreef.
