Abstract:
Sand-sized basaltic glass fragments were recovered in the liner of Core 203-1243B-19R, the deepest recovery from Hole 1243B. Microprobe analysis of 582 glassy cuttings cluster into five compositionally distinct groups, most of which are unlike the lithologic units described on board ship. Drilling operations intended to sweep cuttings from the caving hole and differences between the cuttings and geochemically distinct lithologic units of the upper part of the basement indicate that the cuttings came mainly, if not entirely, from the lower part of the hole. They give information about the part of Hole 1243B that had poor core recovery. Enriched mid-ocean-ridge basalt (MORB) from the upper part of the hole and transitional MORB from two groups of cuttings from sources low in the hole may be a trace of the Galápagos plume on the Pacific plate or may be a normal consequence of eruptions from two distinct magmas on fast-spreading crust.
