Abstract

Hysteresis loops and direct current backfield curves were measured on 146 samples from Hole U1439C, 54 samples from Hole U1440B, and 56 samples from Hole U1442A, which were cored during International Ocean Discovery Program Expedition 352. Saturation magnetization values correlate fairly well with the downhole lithology. For samples from Holes U1439C and U1442A, hysteresis parameters plot in different regions of the Day plot depending on whether their composition is boninitic or andesitic. Similarly in Hole U1440B, samples from the various petrologic units plot have different hysteresis parameters. The results show that the magnetic mineralogy varies strongly within each hole.

Site U1440: Expedition 352

According to the hypothesis being tested, the Izu-Bonin-Mariana (IBM) fore arc formed during the period of seafloor spreading that accompanied the rapid rollback and sinking of the newly subducting plate immediately following subduction initiation. According to the related hypothesis of Reagan et al., the deepest volcanic rocks should primarily be fore-arc basalt (FAB), a distinctive type of volcanic rock recovered during dredging and submersible sampling of the IBM fore arc. Both hypotheses predict that FAB is underlain by sheeted dikes, as these are characteristic of crust accreted during seafloor spreading at all but the slowest spreading rates. Reconstruction of the IBM volcanic stratigraphy also provides evidence for the inference that the FAB should be overlain by the initial products of arc volcanism, specifically by (1) Lavas with compositions that are transitional between FAB and boninite; (2) Boninite lavas themselves; and finally, (3) Members of the tholeiitic and calc-alkaline series typical of “normal” island arcs. Drilling at this site provides an important test of the lower part of this sequence. Although the stated aim of drilling at Site U1439 was to core the upper (boninitic) part of the fore-arc volcanic sequence, the aim of drilling at Site U1440 was to core the lower basaltic part of the sequence.
