Santorini Tectonism and Magmatism paper published

Key Points:
• P wave tomography of the upper crust (<3 km) around Santorini delineates basin structures including buried margins and basement faults
• These structures, also seen in seismic reflection images, result from both the integrated tectonic history, as well as ongoing deformation
• Tectonic structures and stresses localize volcanism in regional NE-SW basins, and, within Santorini caldera, along local NE‐SW lineaments

Santorini caldera and magma recharge paper published

Available online at EPSL: https://authors.elsevier.com/a/1YlKR,Ig4G-Zm.  Click here for a PDF.

Highlights

  • There is a shallow low-velocity, high-porosity volume in the north-central caldera.
  • Vents of the first 3 LBA eruption phases correlate with this inner structure.
  • Inner collapse involved reverse faults, volcanic deposits, and/or rock fractures.
  • The low-density volume may cause magma recharge to localize beneath it.
  • The outer topographic caldera formed by relatively coherent down drop.

Story Map for Santorini: Kameni island growth and Minoan eruption phases at Metaxa Mine

Take a look at this impressive Story Map that Evi worked on.

https://nom.maps.arcgis.com/apps/Cascade/index.html?appid=2a6c54875bf743dd8143786a55dcb2b1

It explains the exposures of the Minoan deposits in the Mavromatis Mine and shows the development of the Kameni volcanics.  It is really nicely done.  We went to both places on the Staples field trip spring, 2018.

Fieldtrip Roundup

I hope that you have all recovered from the trip back.  Thank you all for being a great group on this trip, all my colleagues, the tour guide and even the hotels commented favorably on the behavior and level of interest of everyone in the group.

1. I have reconciled the expenses from the trip and we are pretty much on budget.  Each student owes me $363.26. Please transfer this to me using Paypal (emilie@uoregon.edu), cash or a check.  Since you had a ~$210 difference in your student account between the scholarship and the field trip charge, this makes the remaining cost to you ~$153. (Brandon, Ben, Gillean, and Miles see me separately).

2. We will have a summary meeting next week on Monday or Friday afternoon of the week of April 16-17. Let me know which times you can make at: https://doodle.com/poll/mcf6648rrq63cvrp

3. Brandon will let you know where to put your best photos from the trip at the start of next week.  I have been sorting though mine!  Here are two of the group photos and a third of the group at the base of the fault surface.

Logistics

  • I leave Eugene on Tuesday morning March 13. Anything that needs me must be done Monday 1-3 pm.
  • Undergrads: if you need a financial expense document let me know this weekend.  I will email it to you on Monday.
  • Additional copies of the itinerary are in my lobby.
  • 10 printed copies of the Crete field guide are in the lobby of my office.

Travel

  • Bring your passport and check in using the e-ticket confirmation number that you received from Doug Bridges. Check that you can find these this weekend!
  • Luggage allowance: ONE personal item (purse/small bag) and ONE checked bag with maximum weight 15 kg (=33 lbs).
  • Rooming: Go to the  Google Spreadsheet and choose: (i) a roommate and (i) a day for your website posting.  Email Brandon for matchmaking (brandonv@uoregon.edu).

From the Field postings:

  • In the evening of your day give Brandon your text (preferably Word Doc) and photos (either separate or within doc) and he will post it on our Website.
  • The first post will be about the experience traveling to Greece.

Lastly, please review our seminar & trip (though we did not do the trip yet…) in the UO system.  This will help my work and time in organizing the seminar and field trip to be acknowledged.

Greek civilizations presentation – Hooft.
