Accordingly, the geology relates to a \u2018passive margin\u2019 and Cretaceous-Cenozoic cover rocks (sedimentary and volcanic) are remarkably undeformed.<\/p>\n\n\n\n<p>It is clear that the Chatham Islands have behaved as a single tectonic entity with significant vertical uplift during Pliocene time.<\/p>\n\n\n\n<p>The landscape is therefore \u2018youthful\u2019 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.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity has-very-light-gray-to-cyan-bluish-gray-gradient-background has-background is-style-wide\"\/>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/confer.co.nz\/resus2026\/wp-content\/uploads\/2025\/04\/Picture53.jpg\"><img decoding=\"async\" data-id=\"2725\" src=\"https:\/\/confer.co.nz\/resus2026\/wp-content\/uploads\/2025\/04\/Picture53-1024x768.jpg\" alt=\"\" class=\"wp-image-2725\"\/><\/a><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/confer.co.nz\/resus2026\/wp-content\/uploads\/2025\/04\/Picture43.jpg\"><img decoding=\"async\" data-id=\"2726\" src=\"https:\/\/confer.co.nz\/resus2026\/wp-content\/uploads\/2025\/04\/Picture43-1024x768.jpg\" alt=\"\" class=\"wp-image-2726\"\/><\/a><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/confer.co.nz\/resus2026\/wp-content\/uploads\/2025\/04\/Picture333.jpg\"><img decoding=\"async\" data-id=\"2727\" src=\"https:\/\/confer.co.nz\/resus2026\/wp-content\/uploads\/2025\/04\/Picture333.jpg\" alt=\"\" class=\"wp-image-2727\"\/><\/a><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large is-style-default\"><a href=\"https:\/\/confer.co.nz\/resus2026\/wp-content\/uploads\/2025\/04\/Picture23.jpg\"><img decoding=\"async\" data-id=\"2731\" src=\"https:\/\/confer.co.nz\/resus2026\/wp-content\/uploads\/2025\/04\/Picture23-edited-1.jpg\" alt=\"\" class=\"wp-image-2731\"\/><\/a><\/figure>\n<\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Date: 8 February &#8211; 13 February<br \/>\nDeparts from: Auckland<br \/>\nEnds: Auckland<br \/>\nCost ($NZD inc 15% GST): Approx $6500 per person<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[10],"tags":[],"class_list":["post-2593","post","type-post","status-publish","format-standard","hentry","category-post-conference-field-trips"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 -
