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:
Oxide wt % normalized to 88.0 wt % for analytical electron microscopy (AEM). Number of cations on the basis of 25 O except no. 7, where normalized on the basis of 28 O (chlorite formula). No. 5, 6, 8 for Mg values assuming 0.20 Mg in the interlayer site
