Geological and Hence Geomorphological Highlights
In a New Zealand context, the Chatham Islands are unusual because they are so remote from the active plate boundary. Accordingly, the geology relates to a ‘passive margin’ and Cretaceous-Cenozoic cover rocks (sedimentary and volcanic) are remarkably undeformed.
It is clear that the Chatham Islands have behaved as a single tectonic entity with significant vertical uplift during Pliocene time.
The landscape is therefore ‘youthful’ and the geomorphology is clearly the product of differential erosion, primarily driven by prevailing SW wind and sea conditions. The landscape is dramatic in places, punctuated by small intra-plate submarine volcanos (basaltic). This excursion is a rare opportunity to see some remarkable geomorphology in a remote part of eastern Zealandia, some 800-850 kilometres east of mainland New Zealand, in the SW Pacific Ocean.
