MidPacific Seamount. Nineteen buckets of samples available.
1 :   
Comments: Northeast side of seamount dredged - depths of 1800-1500 m. really good bites. 1000 lbs of rocks (450 kgs) in 11 bags. 50% of haul ( what a waste) consisted of Mn encrustation (pavement) up to 6 in (14 cm) thick. Often encrusted was a grey massive limestone. Carbonates - two types. 1) Massive, coarsely crystalline, almost pure white limestone with rare fossil traces. 2) Most of the carbonates consist of biogenic fragments of a reef community. Mollusks (incl. rudist?), benthic & planktonic forams, echinoid spires, and coral fragments. Rocjs are porous. Assemblage is Mid Cretaceous, probably.
