ABSTRACT. STUDY AREA. Analysis of thin sections from the Wind Mountain quadrangle, Burro Mountains, NM, near the Tyrone copper mine, reveals a complex geologic history. Rock samples collected in the study area were cut using a rock saw and thin sections were prepared and analyzed to determine mineral content and fabric patterns. The oldest rocks in the study area are strongly metamorphosed and locally . Oceanic Intraplate Volcanism. GLY 4310 - Spring, 2017. 2. Hot Spots, Trails, and . Aseismic Ridges. Figure 14.1. .
