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 . granitoids. of the northern part of Adamawa Massif, N.E Nigeria. I.V. . . Haruna. Department of Geology. Modibbo. . Adama.
