| Resumo |
Holes 639E and 639F were drilled along the western slope of a tilted fault block in an attempt to recover complete syn- and pre-rift stratigraphic sections and continental basement. Both holes ended in an apparent talus pile or conglomerate that includes cobbles of altered rhyolitic rock. Three small pieces of rhyolite (comprising about 20 cm of sample) were recovered from the bottoms of Holes 639E and 639F in the core catchers of the deepest cores. This note presents geochemical data from these rhyolitic rocks. Also recovered were quartz sandstones, graywackes, metasandstones, and quartz breccias. This assemblage of continentally derived 'basement' material was overlain by mudstones, limestones, and crystalline dolomites (see 'Site 639' chapter; Shipboard Scientific Party, 1987, doi:10.2973/odp.proc.ir.103.110.1987). |
