Geosite Recognition Based on Qualitative-Quantitative Assessment in the Light of Core Geological Features of a Mio-Pliocene Volcanic Arc Setting of the Coromandel Peninsula, New Zealand

Abstract

The far north part of Coromandel Peninsula can be considered a good place for geoeducation and geotourism, which is justified by the remnants of Miocene-Pleistocene volcanic integration with marine environment. These processes in collaboration with old Jurassic and quaternary sediments create a diverse geological and geomorphological constructions forming the abiotic environment of areas surrounding Port Jackson and Fletcher Bay. These two locations have been chosen as two main campsites of the north Coromandel Peninsula, which are maintained by the Department of Conservation (DOC) of Coromandel Peninsula. Hence, the campsites should be considered as main places for camping for the trips of different purposes. They provide an access costal way and/or trails leading to the main geologically important locations presenting some knowable features like Pinnacles and Sugar Loaf spread through the region. To highlight these locations of interests, “geosites,” we developed qualitative-quantitative assessment of geodiversity for geosite recognition based on 8-m DEM and 1:1250,000 scale geological map and QGIS (3.28 “Firenze”) software. The methodology utilizing 8-point evaluation system applied for geological formations of the studied region and its multiplication with morphological slope degree. The result of assessment has been expanded and justified with geological, cultural, and geomorphological database acquired from literature review and direct field trips of the studied areas. The conclusion demonstrates the main geological knowledge of recognized geosites together with description of drawbacks and possible obstacles for tourism and education in the region of the northern Coromandel Peninsula.
