Basalt is the most voluminous of all the igneous rocks. Extensive
field, experimental, petrographic and geochemical studies of basalt
have provided us with a considerable understanding of igneous
petrogenesis, plate tectonics, and crust-mantle interaction and
exchange. One important aspect of geology that has developed over
the last few decades is the study of oceanic basalts. The ocean
basins cover about two thirds of the earth's surface and are
floored by a basement of oceanic basalt that is continuously
undergoing generation at spreading centres and destruction at
subduction zones, a process which throughout geological time is
recognized as the principal means of generating new crust. The
study of oceanic basalts enables us to understand better the
generation and recycling of crustal materials (including the
continental crust), and the exchange between oceanic crust and
seawater via hydrothermal activity. Compositional variations
displayed by oceanic basalts provide windows into the mantle, and
the identification of isotopically-distinct mantle reservoirs
demonstrates that the source of oceanic basalts is heterogeneous
and is controlled by convection and reservoir interactions within
the mantle.
