Speaker: Dr. Wendy Calvin, PhD
University of Nevada, Reno
Topic: Core Spectral Imaging
“Reflectance spectroscopy is a rapid technique for identifying both hydrothermal alteration and primary mineralogy.” Dr. Calvin will explain the evolution of this technology and its applications.
Abstract: Reflectance spectroscopy is a rapid technique for identifying both hydrothermal alteration and primary mineralogy. Minerals have unique and diagnostic spectral properties, and features such as the band center, strength, shape, and width are used to identify species with high confidence. Laboratory spectroscopy has been used since the 1970’s for determinative mineralogy with field portable instrumentation becoming common in the late 90’s. Recent advances in commercial spectroscopy include automated mineral identification and core imaging systems. We have surveyed a number of geothermal drill core using portable field instruments and modern tools that provide spectral image data cubes at < 1mm/pixel. The talk will review the technique including which minerals are diagnostic in various wavelength ranges, compare field instruments with modern core imaging and discuss future projects.
Bio: Dr. Wendy Calvin received her PhD from the University of Colorado in Boulder and is a Foundation Professor and Department Chair for Geological Sciences and Engineering at the University of Nevada in Reno. She has built her career on working with spectroscopic data from terrestrial planets in the solar system (mostly Mars) and has been using the technique for geothermal exploration on Earth since 2002.
