Pre conference field trips

 

FT1: Subduction to subduction: 100 million years on the eastern margin of Zealandia

Leaders: James Crampton, Ben Hines and Tim Little

Date: Sunday 25 - Tuesday 27 November 

Field Trip Guide available here.

Description:  This field trip will traverse 100 million years on the eastern margin of Zealandia, from the mid-Cretaceous
termination of long-lived subduction, through DSCF5159v2small50 million years of gentle submersion on a passive margin, to the rambunctious excitement of the modern plate boundary.  The trip will start in Wellington and deliver you to the conference venue in Napier.  Along the way, we will examine:

  • the youngest Torlesse strata and some enigmatic mid-Cretaceous “cover” beds,
  • Paleogene strata from the transgressive phase of the Zealandian Megasequence,
  • Neogene strata that record the development of the modern plate boundary,
  • Active tectonic features of the East Coast fault and fold belt.

DSCF5110v2smallOn day 3 we will join with Field Trip 5 (Structural Styles and Deformation Fabrics, Emergent Accretionary Ridge, Hikurangi Margin, Southern Hawke’s Bay: from dismembered units and broken formation to tectonic mélange) to examine structural styles and deformation fabrics of the emergent accretionary ridge.  Note also that this will involve a 7-8 km hike over low hills and along a rock and boulder strewn shore platform; a good level of fitness is essential. 

Departs:  Wellington 8.30 am, Sunday 25th November
Returns:  Arrive Napier 6.30 pm, Tuesday 27th November


Participants:  The trip is limited to 21 participants.

Cost:  Costs include accommodation for two nights (two options in Martinborough), breakfasts, and transport.
Processed0020v5Costs do not include lunches (three days) and dinners (two nights).
  • Option 1: Stay at Martinborough Hotel for one night - $340 per person. This option is closed now.
  • Option 2: Stay at Martinborough cabins for one night - $215 per person.

 FT2: White Island

Leader: Brad Scott

Date: Monday 26 November 

Field Trip Guide available here.

Description: White Island is an active volcano 50 km off the BOP Coast. The full day trip will visit the island by boat, taking in the hydrothermal features and the active vents area (conditions permitting) This field trip will view recent eruption deposits, fumaroles, sulphur towers and the crater lake.

P1170464The trip will depart from Rotorua, driving across part of the Rotorua Caldera floor, before climbing over to the northern margin of the Okataina Volcanic Centre and then descend to cross the Taupo Rift enroute to Whakatane.  Once in Whakatane we will board one of the PJ Charter boats and steam out to White Island. After been rafted ashore we will take in the surface expression of the hydrothermal system while walking towards the active crater and crater lake. Enroute eruption deposits and surface hydrothermal features will be seen.  If the weather or volcanic alert prevents us from going, we will look at other cool stuff near Whakatane (Edgecumbe Fault and Matata debris flows and aspects of the Rotorua Geothermal system and Caldera.

Requirements: Need to be able to walk on rough ground. Good shoes and field appropriate clothing are recommended.

Departs: Rotorua at 5.45 am 
Returns: Rotorua at 5.00pm

Participants: Minimum 12 people and Maximum 23 people.

Cost: $250 (light lunch included)

FT4: Hawke's Bay Monocline and Forearc Basin

Leader: Peter Kamp

Date: Tuesday 27 November

Field Trip Guide available here.

Description:IMG 0188 W2

The Hawke’s Bay Monocline refers to a Neogene stratigraphic succession several km thick; having shallow SE dip that comprises the western limb of the modern forearc basin in central and northern Hawke’s Bay. The field trip will involve making a transect by road through the formations exposed within the monocline between Napier and the Mohaka River and its confluence with Te Hoe River. Sites to be visited will give insights to the structure, formational stratigraphy and paleoenvironments of formations mapped within the monocline, particularly of Tongaporutuan to Nukumaruan age. This is a one-day trip and lunch
will be included in the cost.  

Requirements: We will visit outcrops mostly adjacent to country roads so participants will need to have a good level of awareness of road hazards and means of keeping themselves safe.
Departs: Napier Conference Centre 9.00 am.
Returns: Napier Conference Centre 5.00 pm.

Participants: Minimum 11 people 

Cost: $45

FT5: Structural Styles and Deformation Fabrics, Emergent Accretionary Ridge, Hikurangi Margin, Southern Hawke’s Bay: from dismembered units and broken formation to tectonic mélange [Field Trip Full]

Leaders: Jarg Pettinga, University of Canterbury and Carolyn Boulton, Victoria University of Wellington

Date: Tuesday 27 November

Field Trip Guide available here.

DescriptionBroken Formation W

This one-day field trip will investigate structures and fabrics within the emergent frontal accretionary wedge, Hikurangi Subduction Margin. The trip will include a 7-8 km hike extending along the coast from Red Island to Waimarama Beach, and the cost includes transport and lunch. Throughout the day, deformation mechanisms operating within the emergent Makara basin and its bounding structures will be evaluated on the regional scale down to the grain scale. The spectacular exposures seen in the rolling hills and wave-cut rock faces will enable participants to visualize processes occurring offshore today in the seismically, structurally, and geomorphologically active accretionary prism.

Participants of the two day Field Trip 1 (Subduction to subduction: 100 million years on the eastern margin of Zealandia) will join us for the day.

Requirements: A good level of fitness is essential as this trip will include a 7-8 km hike. The initial traverse is over rolling coastal hills, followed by a 5 km hike along a rock and boulder strewn shore platform from Red Island to south end of Waimarama Beach.

Departs: Napier Conference Centre 9.00 am.
Returns: Napier Conference Centre 6.30 pm.

Participants: Minimum 10 people and Maximum 16 people.Scaly fabric w
