ItemSome aspects of sedimentation of the Siluro-Devonian rocks of the Seymour district, Victoria(University of Melbourne, 1964)Quantitative studies of the variation, of the arenite� lutite ratio and of the bedding thickness for outcrops across the Siluro-Devonian sediments in the Seymour East Syncline indicate the following significant features: 1. Bunches of massive, thick, and thin-bedded arenites, referred to as members, many containing cobble conglomerates, suddenly come in over massively�bedded graded and ungraded lutite. 2. The arenite members show graded bedding features which are mostly rhythmic, being especially aperiodically interrupted at their bases, and becoming more regular and pulsating in their upper cycles. 3. Parallel cumulative frequency curves for the bedding of coarse and fine lithologies in these cycles suggest a common origin, viz. their introduction by slump-induced turbidity currents carrying coarse sediment into standing water of at least some depth to allow separation and grading of grain sizes into the distinct lithologies. 4. The siltstones into which the arenite members are emplaced are themselves often graded. Elsewhere, massive, ungraded siltstone resembles the matrices of cobble conglomerates in the base units of tie coarse members. 5. The arenite laminations within the siltstones are regarded statistically, suggesting that their occurrence is accidental. The sandy intercalations are the expressions of the distal portions of stronger turbidites which have penetrated beyond the normal range into the typical pelagic or lutaceous environment. 6. When the pebble traits of petrological composition, bedding characteristics, and shape are quantified for conglomerate localities in the Tallarook and Seymour East Synclines, and the frequencies of the traits contoured, strong trends can be seen. These strends are from the south and southwest along the Tallarook Syncline, and from the S.S.E. along the Seymour East Sync line. 7. Concentrations of pebble traits suggest at least two separate sources, one from the southwest of the Tallarook Syncline, the other to the north and east from the Trawool Anticline. 8. Land plant debris in the core of the Seymour East Syncline associated with the southerly directional structures in the sediments indicate that parts of the High located in the vicinity of the Trawool Anticline were above sea - level. 9. Agreement with current bedding and flute cast data suggest that the contour patterns and modal trends of the pebble traits indicate the conglomerates were emplaced as turbidites, the directions of slumping and ensuing currents being indicated by the trends. 10. The turbidite pattern la consistent with the hypothesis of slowly rising highs in the south, as well as along the line of the Trawool Anticline in Upper Silurian and later time. These movements are regarded as weak expressions of the Downing Orogeny, the effects of which were far more spectacular in Hew South Wales and in Eastern Victoria.
