"In this study, the following facies were identified: 1) red bioturbated mudstone to muddy siltstone (typical of the lower Streetsville member), interpreted as low-energy, shallow marine background deposits, 2) greenish to reddish very fine to fine grained sandstone (interbedded with facies 1 in. coarsening-upward sequences and typical of the lower Streetsville and middle Bronte Creek members), interpreted as higher-energy, nearshore to shoreline traction current deposits, 3) uncommon thin bioclastic calcarenite beds (present in the middle Bronte Creek member), interpreted as higher-energy, nearshore to shoreline traction current deposits, and 4) red, uniform, well sorted, pedogenically-altered siltstone (characteristic of the upper Milton member) and here interpreted as an ancient subaerial loessite deposit in a glacially-influenced setting. New paleocurrent data (175 direct and indirect indicators) suggest a regional shoreline trend of 20°/200°, with a generalized offshore paleoslope direction of 310°"--Abstract, page 1.
