•
•Unit A: brown (7.5 YR 4/4 dry), reddish brown (5 YR 4/4 wet), moderately well laminated, poorly sorted, clayey, sandy, pebbly silt, alternating with well-laminated, poorly sorted, clayey, silty, sandy gravel; basaltic clasts very angular to sub-rounded; no reaction with 10% HCI; maximum observed thickness = 10 cm; indistinct lower contact (dashed line). Unit B: brown (7.5 YR 4/4 dry), reddish brown (5 YR 4/4 wet), unlaminated, moderately well sorted; silty, sandy, pebbly clay; basaltic clasts sub-angular; overall prismatic texture; strong reaction with 10% HCI; maximum observed thickness = 6 cm; sharp lower contact (solid line). Unit C\: Yellowish brown (10 YR 5/6 dry), dark brown (7.5 YR 4/6 wet), unlaminated, moderately well sorted, silty, sandy clay to clayey, sandy, gravely silt; basaltic clasts, rarely up to 20 cm in diameter, sub-angular to sub-rounded; strong reaction ith 10% HCI; maximum observed thickness = 22 cm; indistinct lower contact (dashed line). Unit Cy. light yellowish brown (10 YR 6/6 dry), dark brown (7.5 YR 4/6 wet), unlaminated, very poorly sorted, clayey, sandy, gravely silt; basaltic clasts rarely up to 20 cm in diameter, smaller clasts of flourite and calcite, very angular to sub-rounded; strong reaction with 10% HCI; maximum observed thickness = 6 cm; lower contact basaltic bedrock).)
