Abstract:
Sixty-three major and trace element analyses from Hole 735B reflect known characteristics of the igneous and metamorphic evolution of the oceanic crust at this site. Regular association of ferrogabbro formation with more evolved units suggests either intrusion into a crystal mush (residual melt porosity) or the tectonic incompetence of the evolved units (fracture generated porosity). Relationships of the titanophile elements (Zr, Y, and V) can "fingerprint" magma-crystallizing mineral phases in which these elements are compatible. In this way, a high V, low Zr and Y oxide-crystallizing magma can be clearly distinguished from the main magmatic trend, and a general concentration of high-Zr magmas is found near the top of the hole. This suggests independently of the stratigraphy that different magmas were responsible for the various magmatic cycles. Results of the analyses additionally form the basis for further study of the bulk chemistry of the magmas that formed this locality.
