Strain Partitioning and Dimensional Preferred Orientation in a syn-Tectonic Granitoid, S.E. Nigeria

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...

Electric-field-induced AFE-FE transitions and associated strain/preferred orientation in antiferroelectric PLZST.

Electric-field-induced, antiferroelectric-ferroelectric (AFE-FE) phase transitions are common for AFE materials. To date, the strain and preferred orientation evolution as well as the role of the intermediate FE state during the successive AFE-FE-AFE phase transitions has not been clear. To this end, we have herein studied a typical AFE Pb0.97La0.02(Zr0.56Sn0.33Ti0.11)O3 (PLZST) material using ...

Preferred 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...
