BHEINN SHUARDAIL DOLOSTONE FORMATION:Dolostone; Pale grey to dark grey. Folia�on common.Dark grey chert forms nodules and thin, folded, some�mes 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 lamina�ons and prominent syn-sedimentary structures

BUIDHE CONGLOMERATE FORMATION:Conglomerate; Polymic�c paraconglomerate withvery poorly sorted, large, sub-rounded clasts. Matrix varies between micrite, red mudstone, and coarse sand

BROADFORD LIMESTONE FORMATION:Limestone and sandstone; arenaceous biomicri�c 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. Interbeddedwith fissile micaceous mudstones and siltstones
