Observations on Granite Weathering Phenomena, Mount Keinath, Northern Victoria Land, Antarctica
Rock varnish, erosional grooves, and well-developed cavernous weathering phenomena occur in close association on a small biotite-monzogranite nunatak in the Northern Foothills region, Northern Victoria Land, Antarctica. The grooves, similar in appearance to the ‘rinnenkarren’ described in the karst literature, are developed on steeply inclined (>35°) bedrock surfaces while the rock varnish occu...
متن کاملThe Use of Waterjets in Cutting Granite
High pressure waterjets are now entering use on an increasing scale for primary rock excavation in quarries. In order to assess the parameters required for any such rock cutting operation a series of experiments need to be carried out in which the critical operational parameters are identified. This paper seeks to identify such a standard procedure with an explanation with the reasons for choic...
متن کاملSplenic abscesses at a tertiary medical center in Northern Taiwan.

متن کاملEmanation from Granite Countertops
Emanation of radon ( 222 Rn) from granite countertops was measured using continuous and integrating radon monitors, and in air collected from encapsulated pieces of the countertops. A majority of the countertops emitted a measurable amount of radon. Although the granites contained the precursors, no thoron ( 220 Rn) emanation was detected. Gamma-ray spectroscopy was used to determine amounts of...
