Preferred Orientation in Microstructures
The microstructures of eutectics between compounds were studied for systems MnO-MnS, NaCl-NaF, NaBr-NaF, LiF-NaF, and FeO-FeS. With the exception of FeS, all the compounds had the NaC1-type structure. In the systems having only NaC1-type structures, the lamellas of the two eutectic phases had matching crystal orientations. There was less consistency among the eutectic systems, however, than bet...

متن کاملPreferred orientation of quartz in a chert breccia.
Preferred orientation of minerals hitherto has been studied almost exclusively in metamorphic and igneous rocks, which show the most spectacular effects of deformation or magmatic flow. In sediments, preferred orientation of grains controlled by their shape has been discussed by Sander,' but to our knowledge no one has ever reported preferred orientation produced by deformation under diagenetic...
متن کاملPowder Pattern Decomposition with the Aid of Preferred Orientation
A method of decomposition of overlapping reflections in a powder pattern with the aid of preferred orientation is presented. Empirical preferred orientation correction with axial symmetry is used. The method is tested on several sets of simulated powder patterns. Introduction Powder patterns collected at various values of some parameter which influences either the position or the intensity of t...
متن کاملPreferred seat orientation of senior high-school students.
The height of the front of the seat is the primary determinant of appropriate seat size in the school setting. In the present study, this dimension was fixed at 445 mm and, using a brief adjustment period, students adjusted the angle of the seat to their preferred rear seat height (PRSH) under three fixed and one adjustable desk height conditions and for one desk height, under two time conditio...
