Gollar Mine Barite & Sulfides Snow-White Specimens in the Ozarks

摘要

I was just starting out with my graduate school studies at the University of Missouri-Columbia when I was first introduced to the beauty of the Ozarks. My advisor, Dr. Martin Appold, and his doctoral student, Zach Wenz, were preparing a short field expedition to collect sphalerite (ZnS) samples for fluid inclusion studies on Mississippi Valley Type (MVT) ore deposits. In wanting to be an oh-so-helpful and eager new student, 1 politely asked if I could go along as an assistant and get some field experience. They obliged and a few days later, we were off southward for my first taste of the Ozarks.
