Using Geologic Principles And Data To Create A Symphony For Wind Ensemble, Thomas J. Davis
2022 Symposium
Geology and geologic processes have featured in many pieces of classical music such as Alan Hovhaness’ symphonic works after Mt. St. Helens and Glacier Peak but these pieces are impressionistic and only take general inspiration from the geology of their subjects. This paper describes the creation of Tectonics (2021) a piece which incorporates and describes many geologic principles and processes, such as mantle convection, through the musical form of cannon, the formation of fold and thrust belts whose cross sections are directly visually recreated in the score, and the physical dynamics of earthquake waves demonstrated through variations of pitch and …

2022 Symposium
U/Pb radiometric dating of zircon is one of the most widely used methods to determine the crystallization ages of igneous and metamorphic rocks and the provenance of sedimentary rocks. Eastern Washington University (EWU) has collaborated with the U.S. Geological Survey (USGS) to build a mineral separation lab for isolating zircon (and other) minerals for analysis. This lab was completed in Fall 2022 and is currently being transferred to the new ISC for future use. Graphically illustrated below are the methods used for sampling and pulverizing the rock, as well as grain mount preparation techniques. One of the EWU projects that …
