Magnetic Characterization Of Iron Formations From Drill Cores Near Iron Mountain, Michigan, Adren Rigdon
Magnetic Characterization Of Iron Formations From Drill Cores Near Iron Mountain, Michigan, Adren Rigdon
Dissertations, Master's Theses and Master's Reports
The magnetic properties of the ~1.88 Ga Vulcan Iron Formation and Felch Formation were investigated from samples taken from three drill cores through the Felch Trough, north of Iron Mountain, MI. The conducted analyses included measurements of natural remanent magnetization, magnetic hysteresis, first order reversal curves, magnetic anisotropy, scanning electron microscopy, and electron dispersive spectroscopy. The data is compared to the results of a previous magnetic characterization study conducted on surface outcrop samples on two members of the Vulcan formation, the Curry and Traders members, near Iron Mountain, MI. Two distinct members of the Vulcan Formation were identified in the …
