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
A bumper turnout to our May meeting was rewarded with Mike Isaac´s rofessional and entertaining explanation of how the GNS QMap series was mapped and put together. This as preceded by Bruce Hayward´s explanation of the science behind the recent news of earlier eruptions from Rangitoto and that the conclusions need to be treated with caution until such time as they are found to be reproducible or not. He also gave brief account of Holocene beach rock at Bucklands Beach cemented by motukoreaite and containing a record of higher mid Holocene sea level. In April, Roger Briggs led 25 Geoclubbers from as far afield as Palmerston North and New Plymouth, around some of the interesting rhyolitic caldera deposits of the east coast of Coromandel Peninsula. Many thanks for a most enjoyable and educational trip Roger. In May an horrendous weather forecast was not matched by the real thing but resulted in only 5 members enjoying the field trip to see the quartz sand quarries of Glorit and Tapora and the most interesting processing plant that removes impurities so the product can be used for glass-making, board and concrete block fillers and sand blasting.
