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 (Geoscience Society of New Zealand) and membership of the Auckland branch section - GeoClub. Some belong to one or the other and some belong to both.

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 large crowd that turned out for the April meeting was rewarded with a brilliant talk from Ian Smith about the chemistry of Auckland's basalt volcanoes and its meaning in understanding how and where they erupt and how much warning we may have of the next eruption. He also commented on the geochemistry of lava samples in the recent Rangitoto drillhole that does not support a recently publicized hypothesis of eruptions prior to 600 yrs ago. Hugh Grenfell gave an interesting account of the manufacture of tourist souvenirs in Italy in the 19th century by the placing of coins in blobs of hot magma, then letting them cool and solidify. Thank you Ian and Hugh.
27 members participated in the 4 day weekend trip from Taumaranui to Whanganui led by Julie Palmer of Massey University. The weather co-operated, enabling everybody to enjoy the geology, the beaches and even the odd coffee. We had a long day driving down the Forgotten Highway via the Tangarakau Gorge to Hawera on the first day; a more gentle transect from west to east along the Pliocene-Pleistocene coastal sequence to Whanganui on day 2; and several sites nearer Whanganui on Mon AM, before everyone headed off on their merry way. Highlights included an 1800 year old charred tree stump buried by Taupo Ignimbrite, early Miocene coal seams at Tangarakau, large fossil crabs, digging out spherical concretions, abandoned kittens, a moa butchery site, Mt Taranaki mass flow deposits, fossil channels, trace fossils, fossil shell beds, the climate-controlled sea-level cycles recorded by the sedimentary sequence, and climbing Durie Hill tower made of Pleistocene limestone.
