Facies code | Lithology | Sedimentary structures | Depositional process and interpretation |
Gm | Matrix supported cobble to conglomerate rounded to sub rounded; fine-to medium sand coarse may be pebble; poorly sorted. | Massive ferruginous lamination. | Cohesive debris flow [13] . |
Fm1 | Claystone (light grey, 5YRN˚6), silteous, pyriteous, fine-grained sandstone (<2 mm), poorly sorted. | Mould of pyritic gastropod | Low energy; deposition from suspension or from weak traction current [12] . |
Fm2 | Claystone/siltstones with layers of silt (moderated red color, 5R5/4); fine grained of sandstone (<2 mm); micaceous, crumbly piles to aggregates pyrite. | Fine horizontal laminated | Low energy; deposition from suspension or from weak traction current [12] . |
Fm3 | Claystones with layers of silt (yellowish-orange color, 10YRN˚4) fine grained of sandstone (<2 mm) without pyrite. | Fine horizontal laminated | Low energy; deposition from suspension or from weak traction current [12] . |
Fm4 | Claystones (yellow brown color, 10YR6/6); organic matter fine grained of sandstone (<2 mm) without pyrite. | Bioturbation | Low energy; deposition from suspension or from weak traction current [12] . |
