Petrography of Middle Triassic Cross-Bedded Sandstones in Northeastern British Columbia

Abstract

<p> An attempt is made to determine compositional and textural trends in the direction of sediment transport in middle Triassic cross-bedded sandstone samples collected from northeastern British Columbia. Petrographic measurements of textural and compositional properties were made and a multiple regression analysis was performed on 27 samples collected from a particular lithological unit. The general petrographic aspects of middle Triassic sandstones were investigated and are discussed.</p>
