Vertical sequences of shallow sediments below the park. Figure has 5 cross sections that show sand, shell material, rip-up clasts, rooting, mud- or sand- filled burrows, horizontal laminations, planar laminations, trough cross bedding, parallel laminations, and/or mud lenses, in addition to relative size of clasts.
Vertical sequences of shallow sediments below the park. See figure 6 for cross-sections of the
underlying sediments. (A) Composite vertical sequence of Holocene and Pleistocene sediments for the Portsmouth area
of North Core Banks (after figure 10 from Heron et al. 1984). (B) South Core Banks sedimentary sequence of Johnson
Creek relict inlet fill is a fining-upward wave-dominated inlet sequence of cross-bedded sand and shell (after figure
2.16 from Moslow and Heron 1994). (C) Stratigraphy from back-barrier margin of South Core Banks. The basal unit is
a burrowed and ripple-laminated silty sand to silty clay of back-barrier origin. It has an abrupt erosional contact with
fine grained sand from an overlying flood-tidal delta. Overlying this is several interbedded units of proximal and distal
overwash and back-barrier salt marsh and tidal flat deposits (after figure 2.15 from Moslow and Heron 1994). (D) The
Back Sound back-barrier sequence from “Middle Marsh” has two stacked, fining-upward flood tidal delta sequences,
interbedded and overlain by thin layers of salt-marsh muds (after figure 2.18 from Moslow and Heron 1994). (E)
Stratigraphy of intertidal sand flat in Back Sound (after figure 2.19 from Moslow and Heron 1994).
