Color of unit: dark gayish-black B. Sediment texture: unconcolidated mud Description of Depostional Interval 3 cm to 18 cm A. Color of unit: grayish black B. Sediment texture: alternating beds of sandy-muds and muddy-sands. Sand coarsen downwardgoing from very fine to fine sized grains C. Sedimentary structures: Massive with traces of dark parallel laminations. Lamination disruptivedby biotubation. D. Paleontologic obsevervation: Live Macoma living just below soapy layer. Lag deposit of acticulated shell E. Additional comments: Graded contact betwen units within the cycle, except for the erosional Description of Depostional Interval 19 cm to 36 cm A. Color of unit: olive gray B. Sediment texture: cycles of sandy mud and muddy sand. Sand coarsens downward from very fineto fine grained within a cycle as well as throughout the unit. C. Sedimentary structures: Remnants of parallel lamination of darker material, but the intervalwould general be classified as massive. D. Paleontologic obsevervation: Coal loacalized. Yolinda shell fragments at base. E. Additional comments: Erosional contact with lower unit. Description of Depostional Interval 37 cm to 76 cm A. Color of unit: olive gray and grayish black B. Sediment texture: Sany-mud. Very fine grain to silt sized grians destributed throughout unit. C. Sedimentary structures: Massive. Extremely bioturbated. A few remnants of parallel laminations. D. Paleontologic obsevervation: Traces of worm borrows abound. Afew scattered shell fragments. E. Additional comments: Muddy shelf environment Description of Depostional Interval 77 cm to pp110 cm A. Color of unit: olive grey mud with dark gray layers. B. Sediment texture: Cycles of muddy-sands and sandy-muds. The individual cycles fine up with erosional contacts between cycles. C. Sedimentary structures: The sand units thin up-section. At the bottom of the is a massive yellowishgray sandy mud about 12 cm thick. Parallel laminations are found in the muddy sand units. Laminations more apparent at the top of this interval. D. Paleontologic obsevervation: none E. Additional comments: Possible turbidite unit. Erosional contact with lower unit. Description of Depostional Interval 111 cm to 138 cm A. Color of unit: olive grey and grayish black B. Sediment texture: Clayey mud C. Sedimentary structures: Massiv E. Possible remnant laminations. D. Paleontologic obsevervation: Shell casts. Bioturbated with traces outlined with a yellowish fill E. Additional comments: no Description of Depostional Interval 139 cm to 160 cm A. Color of unit: black and dark grey B. Sediment texture: mud C. Sedimentary structures: Inclined (4 to 5 degrees) parallel laminations cycles of black and darkgray strat A. D. Paleontologic obsevervation: Burrows < 1.0 mm most parallel to bedding. Bioturbation decreased towardsthe bottom of the interval. E. Additional comments: none Description of Depostional Interval 160 cm to 195 cm A. Color of unit: black to gray/brown B. Sediment texture: Mud organic rich C. Sedimentary structures: massive with evidance of intense bioturbation (90 - 100%) D. Paleontologic obsevervation: Large burrows. Macoma fragments. E. Additional comments: none Description of Depostional Interval 195 cm to 199 cm A. Color of unit: B. Sediment texture: silty-mud C. Sedimentary structures: massive D. Paleontologic obsevervation: small burrows (< 1-2mm) horizontal E. Additional comments: none Description of Depostional Interval 200 cm to 288 cm A. Color of unit: dark gray B. Sediment texture: silty-mud organic rich C. Sedimentary structures: massive intense bioturbation (90-99%). Scattered occurances of possibleremnant stratification. D. Paleontologic obsevervation: A few scattered shell fragments. E. Additional comments: Interval sheared in six loction. Gas ? found in burrows between 235 and 244 cm.
