Skeletal packstone.
In the island boreholes nearest the lagoon, Holocene sediments generally consist of skeletal grainstone in the beach areas, skeletal packstone to grainstone on the islands themselves, and coarse-grained gravel and rudstone to floatstone on the oceanward margin (Henry and Wardlaw, 1986). The reef plate, a marine-cemented reef facies, is part of ...
The texture within each nodule is skeletal packstone dominated by planktonic foraminifers and minor amounts of small benthic foraminifers.
