Ternary diagram showing the relative abundance of quartz, feldspar, and lithic grains and views of what selected compositions would look like. A QFL diagram or QFL triangle is a type of ternary diagram that shows compositional data from sandstones and modern sands, point counted using the Gazzi-Dickinson method. The abbreviations used are as ...
Bernhardt Furniture Company was founded in 1889 by John M. Bernhardt. Until the 1980s, the company was vertically integrated, having a veneer mill, lumber yard and numerous kilns as well as adhesives and particleboard plants. By 1981, Bernhardt began sourcing globally and now has offices in four Asian countries, staffed with 50 employees.
Planar deformation features in quartz identify it as shocked quartz. Planar deformation features, or PDFs, are optically recognizable microscopic features in grains of silicate minerals (usually quartz or feldspar), consisting of very narrow planes of glassy material arranged in parallel sets that have distinct orientations with respect to the grain's crystal structure.
The highest temperature of the three textures, grain boundary migration becomes the dominant mechanism at ~500-550°C. Exhibiting much larger recrystallized grain sizes than the other two regimes, in addition to lobate and highly interfingering boundaries, at these temperatures quartz is completely recrystallized.
