摘要：

Petrographic investigation of rocks from Mason Bay reef indicates that it consists of gabbro and amphibolite similar to, but less evolved than, the Walkers Hill diorite of western Stewart Island. Petrographic examination of samples from Mid Bay reef in Te Waewae Bay, and seismic profiling across it, reveal that this reef is predominantly gabbro with some granite, and is raised up, together with probably Pliocene sediments, along a northeasterly oriented structure. This exposure of basement plutonic rocks at Mid Bay reef indicates total uplift of more than 5000 m in the late Tertiary, effectively separating the Waiau Basin to the north from the Solander Basin to the south.
