A QFL chart is a representation of the framework grains and matrix that is present in a sandstone. This chart is similar to those used in igneous petrology. When plotted correctly, this model of analysis creates a meaningful quantitative classification of sandstones. [24] A sandstone provenance chart is typically based on a QFL chart but allows ...

Tests also have shown that this countertop surface is the most resistant to discoloration from foods and household products among common household surfaces, the second most stain resistant being granite. [3] Countertops are custom made and more scratch resistant as well as less porous than natural quartz surfaces, and don't need to be sealed ...
Jacobsville Sandstone is generally red, due to small quantities of iron oxides, mottled with various pinks, whites and browns. [14] The sandstone exhibits many white streaks and spherical spots, caused by leaching and bleaching, which form sharp boundaries with surrounding colors.
As first demonstrated in the 1979 paper by Bill Dickinson and Chris Suczek, [1] the composition and provenance of a sandstone is directly related to its tectonic environment of formation. Craton sands are clustered near the Q pole. As sandstones, these are known as quartz arenites. Transitional continental sands are along the QF line.
A number of Wikipedia articles contain pro and con lists: lists of arguments for and against some particular contention or position.These take several forms, including lists of advantages and disadvantages of a technology; pros and cons of a proposal which may be as technical as Wi-Fi or otherwise; and lists of criticisms and defenses of a political position or other view (such as socialism or ...
