Lithology description: "the productive horizon at Quarry 6 is in an illitic mudstone between several thin sandstone beds. Underlying the quarry is a 50-cm-thick sandstone bed. Overlying the quarry mudstone is a 50-cm-thick sandstone bed followed by a green 40-cm-thick mudstone bed. Capping the 40-cm-thick mudstone bed is a second 60-cm- thick sandstone bed."
