Plan for Jan 26

This Friday: Michele Paulatto (Postdoc at Imperial College London) will give a talk on Imaging Magmatic Systems

The following Friday (Feb 2nd): continue our discussion of Aegean tectonics by going through the Ring et al. paper

  1. Geomorphology – if we can access the mountains and see the gorges that would be interesting.  One student is particularly interested and going to lead us on some reading there as there is general interest in the topic as well.
  2. Interest in High pressure and temperature units – I believe that this is covered with the Plattenkalk etc.:

Dear Emile and Costas

In the proposed itinerary I have included two locations where we will visit the Kourtaliotis Gorge located in the south central Crete. It is a deep and impressive gorge and we will visit it at the inland, but also, if we want,  at its exit in the famous cost of Preveli (see new kmz). Normal faulting is also obvious at the orders of the small basin that is formed in between two sites (Assomatos fault).

At the time of the field trip, the well known Samaria gorge will be closed and also the nearby gorges of Imbros or Aradena, where the notches and sea terraces prior to the 365 AD Eq are very prominent, will be difficult to visit due to the water presence and the great risk. We can see similar notches and terraces at the broader area of Plakias (Ammoudi area) though.

However, if you wish to visit a gorge at the high mountains we can do it during the third day at the Gonies gorge or further to the south (but will need more traveling) to the Gafaris Gorge.

Regarding the HP/LT metamorphics, we will visit Phyllite quartzites north of Heraklion, however due to retrograde metamorphism is hard to identify HP minerals in the way it can be done in western Crete (west of Chania Province). We have an option to visit a PQ site with Carpholite during the second day near Preveli at the village of Kerame. Plattenkalk rocks are also strongly metamorphosed in places.

Near Preveli, we will have the chance to see blue schists but these are due to a much earlier, probably Eocene to Oligocene metamorphism of the Upper nappes.

If wish I can prepare a small text presenting in brief the proposed sites.

With many greetings

Babbis

 

Intro & Plan for Jan 19

Welcome! We have quite the group.  Remember: the class is pass-fail not graded.

Aegean tectonics (Jan 19 and Feb 2):

  1. Kinematic framework: Miles and Bart will summarize this using figures from the Jolivet and Kreemer papers.  Look over the figures of these two papers.
  2. Temporal evolution of the subduction system and high pressure-temperature terrains: Ellen and Marissa will lead our discussion of this paper.  Read this paper.

Other:

  • Samples from Santorini – where could we access some of these to look at?
  • Fixing Michele’s talk for Jan 26  since some people will miss the Feb 2 meeting.

Draft Itinerary:

  • Complete section through Minoan (Late Bronze Age) eruption deposits:  In the Thira quarry.  Also more distal deposits at the southern beaches – Add to field trip itinerary.

Readings:
