was sufficient to deflect paleoflow to the southeast so that it paralleled the crest of the salt wall before eventually turning north.
The topics include field methods, paleotopography
and stratigraphy, ground stone artifacts, bone and antler tools, mammals, birds, shellfish, and fish.
Work on the paleotopography
of the sands below the ash indicates that Ashfall represents a seasonally water-filled deflation basin (Herbel, 1994).
The lowest member--the Tanner Member--fills in recognizable paleotopography
cut into the underlying Nankoweap Formation.
The lateral variation in oil shale seam can be attributed to differential paleotopography
On a broader scale our research implies: 1) reinterpretation of Late Silurian paleotopography
between the Michigan and Illinois basins, indicating partial exposure of the Wabash Platform during deposition of the Kokomo Limestone and before deposition of the Kenneth Limestone; and 2) the rejection of the subtidal syneresis hypothesis of crack formation in these carbonate sediments.
1996), and changes abruptly in the Trento region across the Giudicarie Line, probably due to previous Permian paleotopography
, increasing towards the east in the Dolomitic Alps.
This unit forms the paleotopography
for all other younger volcanic deposits; fragments of these rocks are common as accessory lithics in overlaying units (Figure 5b).
Current or paleotopography
and evolution of P-T conditions through time describe vertical crustal movements during orogenesis as well as the movement of heat through the crust.
We suggest that the Sharon Formation shows a consistent stratigraphic trend: coarsening upward through the interval in which these fluvial systems were confined to paleovalleys, and then finer-grained through the interval in which these fluvial systems had filled and overtopped paleotopography
on the Bangor surface influenced facies distribution in overlying strata (Pashin, 1993).
