CP1 P-51 well (475-480m) (Eocene of Canada)

Where: Nova Scotia, Canada (43.8° N, 60.6° W: paleocoordinates 42.6° N, 51.9° W)

When: Late/Upper Eocene (37.2 - 33.9 Ma)

Environment/lithology: marine; silty lithology not reported

• Relatively large amounts of silt and sand were present in most samples, with the typical clay content exceeding 50% only in the lowermost 100 m or so. Above that, washing usually only reduced the dry weights by 10 to 35%. The upper 200 m contained large amounts of sand-sized clastics, whereas farther down

•the sands tended to be replaced by silts.

Size class: microfossils

Collection methods: Each sample was oven dried, then weighed. Weights ranged from 100 to over 600g, but most were between 200 and 400 g. No presoaking in any detergent or other chemical was required, as all the samples were unconsolidated. The samples were

•washed through a stack of sieves, the top sieve with a 1.700 mm opening, the middle sieve with a 0.250 mm opening and a bottom sieve with a 0.063 mm opening. The residue was later dried and weighed, and a 5 to 60 g subsample of the 0.250 to 1.700 mm size fraction was set aside for palynological analysis.
