ABSTRACT
The present study deals with the distribution
of Mg. Sr. Fe and Hn along the life stages of
Glyc,.eris glycymeris (Linne’) collected from both
the modern beach zones of A1exandrh and £1 Ari esh.
Egypt. The contents of Mg. Fe and Hn throughout
the different life stages of G. glycymeris show
a general increase start1ng frOlll the neplonic stage
to the adu lt stage. On the contrary. the content
of Sr decreases from the nepionic stage to the adult
stage. An attempt also was made to apply multiple
correlation between the chemical elements and the
shell parameters (length. heigh and thickness).
