Facies Unit Description

CL B2 Planar-stratified siltstones locally truncated by the channelized surface. Normal grading, poorly-developed cross-lamination. Drip marks associated with upright plants. Plant leaves and roots. Total thickness: 1.8 m.

CL B1 Channelized siltstone body of 1 m thick and 10-12 m wide. Strata thin and pinched out laterally towards the erosive bounding surface, and culminate upward into planar-stratified beds and a horizontal upper bounding surface. Climbing ripples, parallel-lamination, clay drapes, linguoid ripples, cross-lamination. Drag marks,wrinkle marks, rill marks, runnel marks, runoff washouts, foam marks, raindrop impressions. Trace fossils. Root structures.

PBL A3 Sharp-based siltstone beds. Normal grading, parallel-lamination, climbing ripples, starved ripples. Tool marks, falling-water marks, raindrop impressions, surface drainage or seepage rill marks, wrinkle marks. Trace fossils. Plant leaves and logs. Beds 0.1-1.8 cm thick. Total thickness: 50 cm.

PBL A2 Sharp-based siltstone beds. Climbing ripples fully developed. Convolute lamination. Individual strata typically include, from base to top, a normally-graded division, a parallel-laminated division, a climbing ripple division, and an upper parallel-laminated division. Tool marks, load casts, raindrop impressions, runnel marks. Trace fossils. Plant leaves. Beds 1.4-12.5 cm thick. Total thickness: 2.2 m.

PBL A1 Sharp-based siltstone beds. Incipient climbing ripples and syndepositional normal microfaults. Upright plant remains rooted in the Ottawa coal. Beds 0.05-1.38 cm thick. Total thickness: 25 cm.
