Elemental and mineral composition of DSDP Leg 84 Holes

Jacques Bourgois, Alain Desmet, Jean Tournon & Jean Aubouin
Ultramafic rocks were recovered from the lower parts of holes at four sites (567, 566, 569, 570) drilled on Leg 84. These sites are on the landward slope of the Middle America Trench off Guatemala. Harzburgites, cumulative texture peridotites, gabbros, dolerites, and amphibolite facies rocks were recognized by p├ętrologie and geochemical analysis (Xray fluorescence, microprobe). Some of these rocks belong to an ophiolitic sequence. They form the basement of the landward slope of the Guatemala...
