Petrology and contact relationships, SW portion PC Mullen Creek mafic complex, Medicine Bow Mts., Wy.
Geologic mapping and thin section petrography of rock units in and adjacent to the southwestern portion of the Mullen Creek mafic complex reveals the presence of a roof zone of a Precambrian layered basic intrusion that invaded a metavolcanic sequence (predominantly hornblende gneiss). This portion …

Petrology of the Mount Airy granite
Modal analysis on slabs, thin section petrography, microprobe analyses, and geological mapping have been performed on the Mount Airy granite and enclosing country rock. The pluton.is unzoned, simply intruded, and composed of a medium-grained, white granite, containing 33-41% plagioclase (An₁₀₋₂₀), …

Sedimentology of the Bullion Creek and Sentinel Butte formations (Paleocene) in a part of southern McKenzie County, North Dakota
… North Dakota.</p> <p>A total of 24 stratigraphic sections were measured and described. In addition, paleocurrent data were gathered from primary sedimentary structures, positions of paleochannel outcrops were noted, and samples were collected. Laboratory work consisted of thin-section petrography, …
