Abstract
This investigation was conducted in order to identify the heavy
minerals of the beach sands of Carmel Bay, and to analyze the distribution
of these minerals, Carmel Bay offers the opportunity to study
heavy mineral assemblages in a small isolated bay, internally divided
by a submarine canyon, containing smaller pocket beaches influenced
by several geological formations and two fresh water streams.
Correlation of the heavy mineral assemblage of each sample with
the sample location clearly indicate that the beach sands can be
divided into two principal mineral suites that are derivatives of the
geological formations in immediate contact with the individual pocket
beaches. The unique nature of each suite is preserved by natural
obstructions that limit the influence of littoral drift and restrict
the exchange of the beach sands.
