Study of diagenetic history of sandstones from six back-arc basins in the western Pacific Ocean indicate, however, that sandstones can undergo a range of different diagenetic processes. To determine whether the diagenetic history of a sandstone is a function of the time of deposition with respect to rifting in the basin, I studied the petrology and diagenetic history of sandstones at seven DSDP sites (285, 286, 297, 299, 445, 446 and 453).

Sandstones which were deposited coevally with early stages of basin rifting (Sites 445 and 446) at a slow rate of burial show greater diagenetic alteration, including pore-space reduction, rim cementation by clay minerals and calcite, pore-fill cementation by clinoptilolite, heulandite, analcite and later sparry calcite, than those deposited during later and post stages of rifting and at a more rapid rate of burial. This observation implies that the large heat flow and fluid circulation associated with rifting provided a strong effect on sandstone diagenetic history, and, thus, that the timing of deposition with respect to rifting will strongly affect back-arc basin sandstone petrology.
