Sediments in Hawke Bay, New Zealand39.2S 177.3E
Sediments line the eastern coast of New Zealand’s North Island, giving it a greenish tinge. They are particularly noticeable in Hawke Bay, which stretches from the Mahia Peninsula in the northeast to Cape Kidnappers in the southwest, a distance of some 100 kilometres.
This area of the New Zealand coast is subject to tectonic uplift, with the land being raised out of the sea. For this reason, the coastal land in this area has significant marine deposits.
Because the central mountain ranges come close to the coast at the north end of the bay, much of the bay’s northerly coastline has deeply eroded tablelands that end in steep seaside cliffs which descend to narrow beaches.
