Drilling Investigation of Bewick and Stapleton Islands
The stratigraphy and sediments of Bewick and Stapleton cays were investigated by rotary drilling. Emphasis has been placed on core collected from the hole, 30 m deep, drilled on the leeward side of Bewick Island. Core recovery using a variety of techniques was variable. However, sufficient material...

| description | The stratigraphy and sediments of Bewick and Stapleton cays were investigated by rotary drilling. Emphasis has been placed on core collected from the hole, 30 m deep, drilled on the leeward side of Bewick Island. Core recovery using a variety of techniques was variable. However, sufficient material existed for chemical, mineral and petrological analyses, as well as for general biological and fabric description. Samples were also selected for radiocarbon dating. Data suggest three and possibly four disconformities in the Bewick core. The youngest hiatus occurs at ca. 3-4 m below low water mark separating Holocene reef and reef flat sediments from pre-Holocene carbonates. An attempt has been made to interpret changes in environments of deposition in the subsurface, and diagenetic effects. |
