...A. Kate Souders; Carol D. Frost Abstract The 2.68 Ga Phantom Lake metamorphic suite of the Sierra Madre is a volcanogenic, volcaniclastic, and siliciclastic sequence that may have been deposited on or near the margin of the Wyoming Province or, alternatively, it may represent part of an exotic...

...KARL E. KARLSTROM; ANDREW J. FLURKEY; ROBERT S. HOUSTON Abstract Metasedimentary rocks in the Medicine Bow Mountains and Sierra Madre are divided into four groups. The > 3-km-thick Phantom Lake Metamorphic Suite contains strongly deformed metavolcanic and metasedimentary rocks that are crosscut...

... to that of the two felsic suites of intrusions, the 1839 Ma Phantom Lake (06-FF-12) and 1866 Ma Annabel Lake intrusions (08-FF-22). Dike 08-FF-07 (see Fig. 4 for location) is isoclinally folded and strongly lineated along the west limb of the Hidden Lake syncline. Dike 08-FF-07 (see Fig. 2 for location...

...Fig. 10. (A) Initial ε Nd versus time for supracrustal rocks (filled symbols) from the South Pass, Rattlesnake Hills, Bradley Peak suites (this study), and the Phantom Lake metamorphic suite of the Sierra Madre ( Souders and Frost 2006 ). Also plotted are data for samples of granitoid plutons...

...David London Abstract The K/Cs ratios of K-feldspars from granitic pegmatites are compared to models derived from the Rayleigh equation. The K/Cs and K/Rb ratios of K-feldspars and micas exhibit decreasing values when plotted against their Cs or Rb contents across cogenetic suites of granites...

...O.V. Lunina; A.A. Gladkov Abstract —We present materials of aerial photography of Cape Rytyi, a unique and most mysterious place on the northwestern shore of Lake Baikal. Photogrammetric survey was carried out using a DJI Phantom 4 Pro V2.0 UAV and provided an orthophoto and a digital terrain model...

... before analysis. During the southward growth of Laurentia, thick (1–2 km) successions of quartz sandstone were deposited within the orogenic belts. Some of the best examples of these deposits are exposed in the Lake Superior region of the northern United States (Baraboo interval; Dott, 1983...

Complete megacyclothem...

... reverse the broadly southward younging of supracrustal rocks described above. The Vulcan Mountain metavolcanic suite and lower Phantom Lake metamorphic suite are intruded by the Spring Lake granodiorite ( Houston et al. 1993 ), which has been dated at 2.71 Ga ( Premo and Van Schmus 1989...
