.... Atmospherically corrected Landsat spectra were compared with petrographic data and laboratory spectral reflectance measurements, using a technique developed by Evans and Adams, to define the provenance of sediments in a wadi within the Meatiq Dome area. Contacts between the dome's granite and granite gneiss core...

...Kathleen G. Muth; Joseph G. Arth; John C. Reed, Jr. Abstract Near Great Falls on the Potomac River, metamorphosed Piedmont rocks of the Glenarm Group were intruded by small bodies of granite and pegmatite after the peak of high-grade metamorphism in the area. Muscovites from two of the feldspar...

... remanie of an entire phase of sea-level rise or fall and, in that sense, they may be slightly diachronous. However, this diachroneity commonly spans only a few millennia to a few hundred thousands of years of sediment starvation/erosion. As such, these beds still provide high-resolution markers with which...

The layers comprise pyroclastic debris largely replaced by sericite, K-feldspar, and chlorite, and are interpreted to represent distal ash-fall tuff deposits that formed during phreatomagmatic eruptions. Their presence throughout the upper Jeerinah Formation indicates that felsic volcanism...
