Porcupine Seabight, Hole U1317E (Pleistocene of Ireland)

Also known as Reef 4074

Where: Ireland (51.4° N, 11.7° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Gelasian (2.6 - 1.8 Ma)

Environment/lithology: reef, buildup or bioherm; cherty/siliceous claystone and floatstone

• coral-bearing sediments and thickens to 155 m on the summit. The corals occur as gravel-sized fragments to branches of several centimeters long and trending right side up. They are embedded in a fine-grained matrix of clay and calcareous bioclasts, including nannofossils, foraminifers, mollusks, and echinoids. A 6-m-thick coral-bearing unit, overlying the regional unconformity, occurs 750 m downslope at Site U1316

• fine-grained matrix of clay and calcareous bioclasts

Size class: macrofossils
