(Table 4) Mineralogy at DSDP Leg 55 Holes
On Leg 55, cores were takenfrom three seamounts in the Emperor Seamount chain: Ojin, Nintoku, and Suiko Seamounts. At the drilling sites the water depth was 1300 to 1700 meters;... -

The authigenic minerals contained in the altered basal intervals of volcaniclastic sediments from Sites 447 and 450 of Deep Sea Drilling Project Leg 59 are dioctahedral smectite... -
(Table 1) Mineralogy of veins in basalts at DSDP Hole 61-462A
Numerous veins are present in basalts recovered from Hole 462A, Leg 61 of the Deep Sea Drilling Project. Three mineral assemblages are recognized and stratigraphically... -
(Table 1) Mineralogy of sediments at DSDP Site 61-462
Two holes (462, 462A) were drilled at Site 462 in the Nauru Basin, within an area formed at a fast-spreading Pacific-plate boundary 145 to 155 m.y. ago. Forty-eight sediment... -
(Table 1) Mineralogy at DSDP Leg 62 Holes
Sixty-nine sediment samples of Deep Sea Drilling Project Leg 62 were mineralogically examined by X-ray diffractometry, and gasometrically for their carbonate content. Most... -
(Table 1) Bulk and clay mineralogy at DSDP Leg 64 Holes
During Leg 64, eight sites were drilled on a transect from young ocean crust to continental crust off Baja California, in the central part of the Gulf of California, where high... -
(Table 1) Mineralogy of DSDP Leg 65 sediments
During Leg 65, four sites were drilled near the mouth of the Gulf of California where high sedimentation rates made it possible to sample young oceanic crust near the ridge... -

Extensive dirty ice patches with up to 7 kg/m**2 sediment concentrations in layers of up to 10 cm thickness were encountered in 2005 and 2007 in numerous areas across the... -
(Table 1) Mineralogy at DSDP Leg 79 Holes
Four sites in the region of the Mazagan Plateau off northwest Africa were drilled during Leg 79 of the Deep Sea Drilling Project. Bulk mineralogy and clay mineralogy were... -

The clay mineralogy of Lower Cretaceous deep-sea fan sediment in the western North Atlantic is dominated by smectite in most intervals, and by illite in samples from intervals... -
(Table 1) Clay minerals at DSDP Hole 93-603B
Cretaceous sediments encountered in Hole 603B contain a 17 Å smectite as the principal clay mineral, with lesser amounts of illite, kaolinite, and randomly interstratified... -
