sand," Paul rattled off, "sodic carbonate, slaked lime, cutlet, manganese peroxide--there you have it, the finest French plate glass, made by the great St.
Among their topics are the provenance and alteration of feldspathic and quartzose
sediments in southern Mexico: an application of Krynine's hypothesis on second-cycle arkose, the paleomagnetism and rotation history of the Blue Mountains in Oregon, Late Cenozoic uplift and shortening in the central California Coast Ranges and the development of the San Joaquin Basin foreland, local-to-distance provenance cyclicity of the southern Front Range in central Colorado: insights from detrial zircon geochronology, and Cenozoic basin evolution in the Indus-Yarlung suture zone and High Himalaya.
This interpretation is applicable only for the first cycle sands, whereas sands derived from recycled quartzose
sedimentary rocks and preferentially sorted during transportation and deposition provide no information on the weathering history of the source rock (Tawfik et al., 2017).
The facies that make up the continental shelf are the platform (silt and clay) and continental muds, sands (quartzose
and bioclastic), terrigenous gravel and shells.
A few Upper Jurassic Weimei formations composed of fine-grained metamorphic quartzose
sandstone, silty slate, and calcarenite as well as Quaternary sediments distributed along valleys also crop out in the orefield (Figure 2(a)) .
More specifically, type-1 ordinary Portland cement (a density of 3.15 g/[cm.sup.3] ) without any coarse aggregate is used, and quartzose
powder with an average particle size of 4.2 [micro]m is adopted as a filler.
The age of orthoquartzite and quartzose
sandstone in the Matthews Lake Formation, the lower unit of the Ellsworth Group in the NRB, is constrained by earliest Cambrian detrital zircon in the basal beds (Fyffe et al.
That area was left blank on the published version, apparently after correspondence with Clarke who had by then made several more trips to the Illawarra, and who found that west of its delta the Shoalhaven River was incised into older sandy siltstone and highly quartzose
sandstone of marine origin (the modern names are Berry Formation and Nowra Sandstone).
It is formed by thick alternations of quartzose
conglomerates and subordinated quartzarenites, passing in the upper ten metres of the section to dark pelites.
In the quartzose
sandy limestone of the Pakri Formation, Fe-Ti oxides have often precipitated as encrustations around quartz grains (Fig.
It consists of red-brown to yellow-brown and mauve-red, medium to coarse-grained massive weathered quartzose
sandstone with thin beds of micaceous sub-arkosic sandstone.
Peter Sandstone, and consists of very pale brown to yellowish red, fine- to medium-grained, quartzose
sand, the coarser grains of which tend to be rounded, but in many places the grains exhibit faceted quartz overgrowths that produce a conspicuously sparkly surface in outcrop (Clayton and Attig, 1990).
