Structural map of Shinkai 6500 Dive 1056. Note changes in bedding direction near sample
site R7 and R2, as well as variation in amount and orientation of jointing
of strata that dip moderately (30-40°) northwest (Fig.
6
). These strata are cut by
east-west striking faults and locally involved in east-west trending folds (e.g. Fig.
6
just south of sample site R7). In contrast with the overall trench-parallel, north-
dipping sequence of strata at the 1056 dive locality, outcrops east of the main dive
track strike northerly (perpendicular to the trench) and expose the limb of a tight fold
(Fig.
4d
). North of the dive track bedding is broadly folded, as indicated by the
