- W1967984753 abstract "An early Paleozoic failed rift, a local precursor of Gondwana fragmentation, was characterized by a steep, rugged northern terminus, with depositional slope decreasing longitudinally southwestward, where the trough opened toward a major ocean basin. There is a marked north—south zonation of the following facies: (1) boulder conglomerates showing crude horizontal stratification in the lower half, with gently inclined stratification and lenticular arrangements, including locally cross-bedded sandstones, in the upper half. These are interpreted to have been deposited in confined intermontane valleys which, following aggradation, developed into a gravelly braided stream complex. The conglomerates merge upward and southward into (2) red arkosic sandstone exhibiting weakly developed vertical arrangements of scour-based, massive pebbly sandstone overlain by cross-bedded sandstone, with thin red siltstones infrequently preserved at the top. Thick sets of planar cross-beds are attributed to deposition on the slipface of transverse bars; cosets of smaller-scale trough cross-beds were deposited in advance of some bars and on top of others. There is evidence that bar dissection and current deflection occurred during river shallowing and bar emergence. An upward reduction in grain size through the fluvial succession is accompanied by a gradual change in channel geometry to narrow, steep-sided forms. A meandering tendency in these low-sinuosity mixed-load streams may have been inhibited by the lack of binding vegetation along the river margins. The fluvial arkoses interfinger southward with (3) a 1000 m succession of quartz arenites thought to have been deposited on an embayed shelf where the outer margins of the braided fluvial complex were reworked by very high energy storm- and tide-dominated processes." @default.
