Figure F2. A. Fragmented but essentially intact ADCB core (Core 193-1188F-2Z).B. Fragments of rubble as extracted from the ADCB core barrel. In some cases, pieces that could be fit together indicated a coherent core had been cut that fell apart upon extraction from the core barrel. In many other cases, the core is so fragmented that it is not possible to determine if the rubble is a drilling-induced artifact or a result of postcoring disintegration (Core 193-1188F-41Z).
