It was abandoned because of poor drilling conditions Hole 1158B yielded 1.6 m (10.7% recovery) of aphyric to sparsely olivine plagioclase phyric basalt. The basalt is slightly to moderately altered. It too was abandoned because of poor drilling conditions. Hole 1158C yielded 1.61 m (17.1%) of massive diabase (composed of plagioclase, clinopyroxene, and magnetite/ilmenite with a medium-grained subophitic texture) beneath overlying aphyric basalt rubble. Two lithologic units were identified. Unit 1 was similar to A and B and Unit 2 was a diabase. Low-temperature alteration products were present throughout this core. Ba and Zr systematics indicate that Site 1158 lavas were derived from Pacific-type mantle <2 mu after the Indian-type lavas of Site 1157 were erupted on the same flow line. Igneous petrology, alteration, microbiology, structural geology, site geophysics, sediments, and geochemistry studies were carried out.
