Some kinds of quasimartingale atoms are defined and the atomic decomposition for some(B-valued) quasimartingales are made under certain geometric conditions.Conversely
these geometric properties are characterized in terms of the respective atomic decomposition.As a result
some quasimartingale inequalities are obtained
which are applied to investigate the relation between some B-valued quasimartingale spaces.
