Desplats Limestone Quarries (Upper) (Eocene of Senegal)

Where: Senegal (14.7° N, 17.2° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: E8 foram zone, Cap des Biches Member (Bargny Formation), Lutetian (48.1 - 41.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithology not reported

• deposited on the outer shelf and subjected to wave action from storms.

• The Cap des Biches Member consists of a thin calcareous conglomerate with chert and phosphate... and overall consists of marls and micritic limestones alternating with levels of chert and phosphate. Limestone blocks from the quarry exhibit ripple marks and hummocky cross stratification at the base.
