Who Are We?
The Geoscience Society of New Zealand is an incorporated society which encourages the advancement of the earth sciences in New Zealand. Membership is open to all people interested in the pursuits of the Society.
The Auckland Branch is one of seven local branches
who organise illustrated lectures, discussion meetings, field trips and social events.
The Branch has two different membership types - membership of the national body (GSNZ) and membership of the Auckland branch section - GeoClub. Some belong to one or the other and some belong to both.
entitles you to receive the GSNZ Newsletter, Branch newsletters and benefit from discounts.
entitles you to a monthly GeoClub Newsletter
by snail or email with information of upcoming talks and field trips (membership form and cost on page 3).

What is "GeoClub'?
Established in 1992 at Auckland Museum the GeoClub is now part of the Auckland Branch of the Geoscience Society of New Zealand at Auckland University. The Club is a mix of enthusiastic amateurs and professionals who share a common interest in the study and understanding of Auckland's geology and fossils and has a membership of approximately 100.
No previous knowledge or understanding of geology is required to become a member, although most of our members started by taking an adult education course or a geology paper at University. The main requirement is an enthusiasm to understand something about the long history of the earth and our region.
Recent Club field trips have included visits to Hokianga, East Cape, Rotorua, Port Waikato, Waihi Gold Mine, Puketotara Peninsula, Kawau Island, the Miranda coast, Piha, Browns Island, Pollen Island, Whangaparoa, the Hillsborough coast, Queens Street building stones, Takapuna fossil forest to mention a few.
Geology is a hobby that families and people of all ages can enjoy. It gets you out into the open air and is a great way to exercise. It takes you to fascinating places you have never visited before and above all you will start seeing the landscape with new eyes. No longer will you just see sheep grazing on hills. You will start to see the lava flows, the fault lines, the folded strata that control the shape of the hills, ancient river terraces and coastal plains.
What do we do?
Monthly meetings at the Epsom Community Centre, 200 Gillies Ave with lectures and slide shows. Parking is available (see below ) with easy access from the motorway.
Books and pamphlets on New Zealand geology available at wholesale prices. Expert assistance available to help identify your problem rocks, minerals or fossils.
Frequent field trips of half or full day duration in the weekends throughout the year
. Car-pooling is encouraged. Periodic long weekend field trips to interesting geology further from Auckland, with costs kept low with budget accommodation.
NEXT MEETINGS & FIELD TRIPS
The June club meeting brought out larger than usual numbers and everyone sat behind three rows of tables that became debris flows of moving rock specimens. Hugh told us how to distinguish and name the common igneous rocks; Bruce sieved and spilled a bag full of gravel and sand into all the different size classes that we should use in describing a clastic sedimentary rock; Wendy had the difficult job of explaining the chemical and biological sedimentary rocks and how to know them; with Garry finishing the evening in glorious metamorphic style with lots of gneiss schist, slate and marble. Many thanks to all four for their preparations and presentations. On Sun 28th Jun a large crowd of 40 members meandered their way around a narrow "track/boardwalk/stepping stones" at the foot of the Parnell cliffs to see weathering in action as a 9 year old raised walkway lined with local Waitemata Sandstone cobbles is literally frittering away at mean rates of 5 mm/yr but up to three times that fast. We also refreshed our understanding of the Bouma sequence using the remaining exposures of Waitemata Sandstone on the same route. Most of us then moved to Orakei Basin where we viewed the two freshest of the remaining tuff exposures (under the newly widened railway bridge and on the point beyond the ski club). For many this was the first time they had circumnavigated the inside of the basin since the 2.88 km circuit walkway had been completed.
