Hole 504B now extends over a kilometer into basement, nearly twice as far as any other DSDP hole, and it is the only DSDP hole to have clearly penetrated into the intrusive sheeted dikes that underlie the extrusive pillow lavas of the upper oceanic crust. At Hole 504B, Leg 83 continued an ongoing DSDP effort that began during Legs 68, 69, and 70 in 1979, and also included part of Leg 92 in 1983. 71 cores; 514 m cored; 0 m drilled; 21 % recovery
Comment:
Depth, sediment (m) is the sub-basement depth (m), Sample 70-504B-37-1,76-80 calculated after Yeh and Savin (1977, doi:10.1130/0016-7606(1977)88<1321:MOBMOA>2.0.CO;2), sample 83-405B-80-1,106-111 calculated T = 200-250 °C calculated after Wenner and Taylor (1971, doi:10.1007/BF00643332)
