  1. RANGITOTO ISLAND FIELDTRIP

Tuesday 28 November

Leaders: David Lowe, University of Waikato and Peter de Lange, Department of Conservation, Auckland

The trip is scheduled from ~9:00 am to 3:00 pm. Rangitoto is arguably Auckland’s most beautiful and omnipresent landscape feature. Guarding the entrance to the Waitemata Harbour, Rangitoto is a symmetrical, ~6-km wide, basaltic shield volcano that last erupted ~550–500 cal. yr BP (c. 1400–1450 AD), not long after the arrival and settlement of Polynesians in the Auckland region (c. 1280 AD). It is by far the largest, and the youngest, volcano in the Auckland Volcanic Field (AVF). The AVF consists of approximately 53 individual eruptive centres, all of which are within the boundaries of the Auckland urban area. Recent research (mainly cryptotephra studies on sediments from Lake Pupuke and wetlands on Motutapu Island, and analyses of a 150-m-long drill core obtained in February, 2014) has revealed that Rangitoto has a much more complex history that previously thought, and may be better viewed as a ‘volcanic complex with multiple episodes of eruptions’. In summary, activity commenced c. 6000 cal. yr BP involving minor effusive and pyroclastic volcanism until 650 cal. yr BP, when a voluminous shield-building phase took place from c. 650–550 cal. yr B.P. The final phase of activity, from c. 550–500 cal. yr BP, was explosive and less voluminous, producing scoria cones at the summit.

The flora on Rangitoto are unique among the islands in the Hauraki Gulf because of the island’s young age, and the fact that technically Rangitoto is an “oceanic” island. Because Rangitoto emerged from the sea and was never connected to the mainland, then its flora and fauna are derived entirely from long distance dispersal. The island contains around 582 vascular plant taxa of which 228 (39%) are indigenous. Ecologically, Rangitoto is marked by the dominance of pohutukawa (Metrosideros excelsa): the island supports the single largest tract of this forest type in New Zealand. Other special botanical features make the island a truly fascinating place to visit.

Depart: 9am Ferry – meet at Downtown Ferry Terminal building (99 Quay St), Auckland, by 8.50 am. The Fullers Ferry will depart from Pier 2 of the Ferry Terminal at 9.15 am. Tickets can be purchased from Fullers Ticket Office on Pier 1.

Cost: $35 included fieldtrip guidebook ad packed lunch. In addition, you will need to purchase your own return ferry ticket ($30 return) on the day

Note: You need boots or strong trainers/shoes, a raincoat/windproof is essential, and you must carry a warm jumper in backpack in case of bad weather. Showers are always possible but, if sunny, a sun hat and sun block are needed. Further information is here

 

  1. NEW VIEW OF THE MIOCENE WAITEMATA BASIN: INITIATION AND FLUID MOBILITY

Saturday 2 December to Sunday 3 December

Leaders: Kathy Campbell, Bernhard Sporli

On this two-day field trip north of Auckland we will visit two key localities of the Waitemata Basin to explore the paleoenvironmental setting of early Miocene sedimentation upon greywacke basement rocks (Mathesons Bay) at the onset of the modern subduction plate boundary, and to examine abundant evidence for fluid mobilisation and methane seep signatures associated with deep marine turbidites (Mathesons Bay, Tindalls Bay) in upper Waitemata strata. The field trip will focus on a range of well exposed and spectacular Waitemata Basin outcrops – including cold seeps, unconformities, trace and body fossils, liquefaction, gravity flows etc.  We have booked the UoA marine lab accommodation located at the beautiful Goat Island for the trip.

Terrain: MB – relatively easy walking but bouldery in places (<2km); TB – 2-3km of flat beach.

Depart: University in minibuses 9am Saturday 2 December, returning late afternoon Sunday 3 December.

Cost: $80 including food, accommodation for the Saturday night and transport

Maximum 20 participants

 

  1. URBAN ENGINEERING GEOLOGY AND LANDSLIDE HAZARDS FOR A CITY ON THE MOVE

Saturday 2 December

Leaders: Warwick Prebble (Beca), Martin Brook and Nick Richards (University of Auckland)

The fieldtrip includes visiting some subdivisions on slippery slopes, crumbling cliffs retreating back into established suburbs, the Waterview Connection Tunnel, the Southern Landslide Zone and Beachlands in east Auckland.

Depart: University in minibuses 9am Saturday 2 December, return late afternoon.

Cost: $40 includes transport and packed lunch

 

  1. FOSSIL HIGHLIGHTS OF AUCKLAND

Saturday 2 December to Sunday 3 December

Leaders: Bruce Hayward and Ian Geary

You will visit some exciting new fossil sites and the best of the rest. Stops include late Eocene leaf and freshwater mussels of the Drury Coal Measures, NZ´s only soft body worm fossils and the world´s best submarine-canyon-wall trace fossils (Bartrum Bay, Muriwai; early Miocene), newly recognised Pliocene estuarine and fluvial deposits containing diverse fossil fruit and leaves and second NZ records of fossil bracket fungi and sea grass, and source of NZ´s first well preserved fossil mosses and lichens (Beachlands & Weymouth, Pliocene), rich estuarine Kaawa Shellbeds (moulds; Weymouth, Pliocene), Early Pleistocene moa footprints (Muriwai), Middle Pleistocene swamp kauri deposit (Ihumatao), NZ´s best fossil forest preserved in a lava flow (Takapuna) and NZ´s best fossil forest knocked over and preserved beneath Late Pleistocene basaltic base-surge tuff deposits (Maungataketake). Make own arrangements for accommodation Fri and Sat nights. Transport will leave each day from University. Optional drop off at Mangere Airport on Sun for flights after6.30 PM. All except the Sat PM visit to Bartrum Bay are easy access but will require footwear for soft sediment up to 3 cm deep. Access to Bartrum Bay involves reasonable physical ability to negotiate a steep descent/ascent.

Depart: University in minibuses at 9 am each day, arrive back late afternoon each day

Cost: $80 includes transport and 2 x packed lunches

Note: please do not book flights home before 6.30pm on Sunday 3 December.

 

  1. HISTORIC BROKEN HILLS GOLD EPITHERMAL AU-AG MINE, COROMANDEL

Depart: 8.30 am University, return 6 pm

Cost: $40 includes transport and packed lunches
