A paleomagnetic study was conducted to gain a better understanding of the geology and structure of Neal Hot Springs and the surrounding areas. The primary objective was to constrain magnetic and gravity field models and correlate igneous rocks. This study was conducted by students and faculty in geophysics field camps from the Colorado School of Mines, Boise State University, and Imperial College London. Personnel from the USGS also helped in this survey.
In this study three different types of measurements were made. The first was in situ magnetic susceptibility measurements made with a handheld meter. The second was measurements from small core samples that were drilled using a diamond tipped pipe drill. Core samples were oriented by azimuth and hade using a magnetic compass and sun dial, then marked before being removed from the host rock. The core samples were then taken to a laboratory for analysis. The third measurement was a precise density measurement made from a hand sample. Core samples were sent to a USGS laboratory, results of the core sample analysis had not been finished at the time of this report.
