10. MICROFACIES OF SOME SEDIMENTS FROM THE WESTERN NORTH ATLANTIC: PALEOCEANOGRAPHIC IMPLICATIONS (LEG 44 DSDP)'
We charactenzed the microfacies of sediments encountered dunng Leg 44 on the basis of coarse fraction mineralogy (&> 125 pm), silt mineralogy (63>1#~>20 pm), clay mineralogy (&<2 pm), silt and clay particle size distributions. and calcium carbonate contents. Secondly we attempted...
