Meeting/Event Information

Technical Talks: The Minnesota Section of AIPG holds technical talks September through May, generally the first Tuesday of the month. The talks are designed to fulfill 1 Professional Development Hour (PDH). Professional Geologists, as licensed in the State of Minnesota, are required to complete 24 PDHs every biennium licensing period, including 2 PDHs of ethics.  The technical talks feature important subjects of interest to professional geologists.

The cost includes a buffet lunch and is $21 for non-members, $16 for members, and $0 for students when registering in advance.  We have limited same-day registration for $25. 

*During the pandemic, we are webcasting our Technical Talks.  The cost is $10 for non-members and $5 for members. You must register by 11 AM the day of the talk to be sent the login link/information. Students may attend free of charge. Fees go toward supporting the online meeting platform and the Education Fund. Your contribution to the Education Fund helps support many activities, please see our Giving Back page.

As always, non-members and non-geologists are welcome to attend!

Statistical Analysis of Small Structures in Rotated Crustal Blocks near the Húsavík-Flatey Fault, Northern Iceland!

by Natalie Hummel, Carleton College

 

Presentation Abstract

The right lateral Húsavík-Flatey fault in northern Iceland provides a unique opportunity to observe an oceanic transform fault on land. Structural and paleomagnetic measurements from lavas and dikes on Flateyjarskagi peninsula indicate that rocks adjacent to the fault have rotated clockwise more than 100°. I examine the effect of this rotation on the orientations of small faults and vein zones near the transform. I also use patterns in small-scale data to build on models of the style of deformation surrounding the fault. Previous studies provide constraints on the extent of rotation across Flateyjarskagi, which I use to estimate the expected orientations of rotated structures. The orientations of some small faults are consistent with expected rotations, but many structures appear to post-date rotation. Rotation of an older subset of the small faults on Flateyjarskagi accounts for patterns that have previously been attributed to variations in the stress field near the transform.

 

Biography

Natalie Hummel graduated from Carleton College with a degree in geology in 2020. She has interests in structural geology, geophysics, and low temperature thermochronology. Natalie is presenting work from her undergraduate thesis, which she completed with Dr. Sarah Titus. This year, she is working on structural geology research as an Educational Associate for the Carleton Geology department while she applies to graduate schools.
