Foliaon common. Dark grey chert forms nodules and thin, folded, somemes boudinaged layers. Infrequent white chert also forms nodules and layers LONOCHAN SANDSTONE FORMATION: Sandstone; Reddish brown arkosic arenite. Fine to medium grained, moderately to well sorted with sub-rounded clasts. Cross bedded with planar laminaons and prominent syn-sedimentary structures BUIDHE CONGLOMERATE FORMATION: Conglomerate; Polymicc paraconglomerate with very poorly sorted, large, sub-rounded clasts. Matrix varies between micrite, red mudstone, and coarse sand BROADFORD LIMESTONE FORMATION: Limestone and sandstone; arenaceous biomicric wackestone interbedded with quartz-rich sandstone. Quartz grains absent at the base of the unit and increase in abundance up sequence to small pebble- sized clasts STARSAICH SANDSTONE FORMATION: Sandstone and mudstone; Fine to medium grained, well sorted sub-lithic arenite with sub-rounded clasts and infrequent cross bedding.
