Embayed texture
WebJun 30, 2024 · The sample is characterized by a heteroblastic to homeoblastic texture and shows a mosaic microstructure with strained crystals and curved-to-embayed grain boundaries (Fig. 1 h). It contains low amounts of dolomite, and relatively high contents of Fe (486 ppm) and Sr (338 ppm) as trace elements.

WebHandout On Textures - Stellenbosch University WebMay 1, 1985 · Typical rapakivi texture is a mixture of variously mantled, non-mantled or partly mantled, concentrically zoned, plastically distorted, fragmented, reaggregated, large and small ovoids. Commonly they are potash feldspar often mantled by, and having a variable content of plagioclase. Some display remarkable sphericity.

WebThe exact way in which the cumulus crystals became enlarged by material of similar composition is still not certain, but it must have taken place at the same temperature as the formation of the cumulus crystals because of the similarity in the solid solution composition. By such growth the intercumulus liquid would gradually be pushed out.
