La D├ęsirade Island, Lesser Antilles, Massive coral breccia (Pleistocene of Guadeloupe)

Where: Guadeloupe (16.3° N, 61.0° W: paleocoordinates 16.3° N, 61.0° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Late/Upper Pleistocene (0.1 - 0.0 Ma)

Environment/lithology: reef, buildup or bioherm; breccia

• bedded (up to 3 m thick), commonly inverse-graded, clayey, sand-supported, red breccia. The sand-sized matrix contains carbonate bioclasts dominated by mmsized, geniculate red algae fragments, substratum-originated

•minerals, and volcanic clasts, often coated by mm-to cm-thick encrusting

•red algae. Breccia clasts are a few tens of cm up to 2m-sized reworked corals fragments, commonly entire or fragmented columnar colonies of Orbicella spp., often large fragments of Acropora palmata branches, and rarely broken thin branches of Acropora cervicornis. Rare reworked, overturned, and massive Diploria

•are observed at the base of the Acropora-dominated breccia. Mixing in the same breccia bed of Orbicella fragments with Acropora or Diploria fragments is rare.

• massive coral breccia

Size class: macrofossils
