Eclogitization and Shear Zone Kinematics: Microprobe and EBSD Analyses in Process

By • Jan 20th, 2018 • Category: Honors Thesis, Research

Three of the thin section chips have been sent off to be made into polished thin sections, and with these I will be able to complete an electron microprobe analysis and an Electron Backscatter Diffraction (EBSD) analysis. The microprobe analysis will be able to tell me the specific mineral chemistry of particular grains in my…

Eclogitization in the Lofoten Islands: Petrology-based Hypothesis

By • Dec 19th, 2017 • Category: Honors Thesis, Research

As I continue with my analyses, I have had to split my time between my structural analyses and my petrologic analyses. In the case of the structural component, as a reminder, I am trying to quantify the kinematics of my shear zones’ burial and exhumation. In regards to the petrology, I am looking for distinct…

Shear Zone Kinematics: Fabric Analyses via 3D Strain Calculations

By • Nov 8th, 2017 • Category: Honors Thesis, Research

As I mentioned in my post from last month, recently I have been focusing on making structural calculations for my rock samples in order to meet my research goal of quantifying the kinematics of these shear zones. Aspect ratio calculations and plotting have been receiving most of my attention, and I have been using a…

Eclogitization in the Lofoten Islands: Structural Analysis

By • Oct 22nd, 2017 • Category: Honors Thesis, Research

Much of the first few weeks with my thin sections were devoted to the petrologic aspects of my research. As I mentioned in last month’s post, I carefully analyzed each thin section for the minerals with which it was made up, made preliminary measurements, made decisions on which thin sections would be best to use…

Eclogitization in the Lofoten Islands: Thin Section Arrival

By • Sep 4th, 2017 • Category: Honors Thesis, Research

My thin sections have finally arrived and the wait is over! I sent off 20 small blocks of rock (each no more than 3 inches by 1 inch and approximately half an inch thick) and they came back to me in the form of microscope slides. I can now view my rocks samples using a…

Eclogitization and Shear Zone Kinematics: Geochemistry Data

By • Aug 17th, 2017 • Category: Honors Thesis, Research

After six weeks of waiting, I have received my samples that were processed for geochemistry but still await the arrival of my thin sections. Thus, I have been spending some quality time with my geochemistry analysis data this month, and have been able to start a preliminary petrographic analysis of my samples. My geochemistry data…

Eclogite Analysis: Thin Section and Geochemistry Sample Preparation

By • Jul 10th, 2017 • Category: Honors Thesis, Research

After many weeks of sawing, cutting, slicing, cleaning, careful labeling, and extremely careful packaging, twenty thin section blocks have been made from my rock samples and shipped off to be transformed into microscope slides. The majority of them came from rock samples taken from Shear Zone 2, at my Nusfjord site, while the minority of…

Methods: Processing Eclogite Samples and Structural Calculations

By • Jun 12th, 2017 • Category: Honors Thesis, Research

I have just returned from the Lofoten Islands, in northern Norway, and I could not be more excited about the rock samples and measurements I was able to collect for my thesis research. One of my advisers, Professor Chuck Bailey, and I braved the arctic snow, hail, wind, and rain in order to go on…

Background: The Geologic History of the Lofoten Islands, Norway

By • May 16th, 2017 • Category: Honors Thesis, Research

Since I will be traveling to the Lofoten Islands, northern Norway this month, (from May 19 – June 1), it is important that the geologic history of the islands is well-understood. Not only will this put what we find today into its geologic context, but it will also help me understand the types of kinematic…

Abstract: Eclogitization and Shear Zone Kinematics in the Lofoten Islands, Norway

By • Apr 11th, 2017 • Category: Honors Thesis, Research

Although a plethora of studies have been done regarding shear zones and eclogites, the true characteristics of the eclogite-facies shear zones in the Lofoten Islands, northern Norway remain enigmatic. Eclogites, high-pressure and high-temperature metamorphic rocks, can form up to 50 km beneath the Earth’s surface, and are found to be one of the only rock…
