| Using the flux growth method pioneered by Prener and others, we could grow idiomorphic apatite single crystals up to ca. 6 mm in size. |
| The decrease in transformation temperature causes a change in the morphology of intragranular ferrite from idiomorphic ferrite to acicular ferrite. |
| Samples collected from the Garnet Hill locality contain idiomorphic garnet porphyroblasts up to two centimeters in diameter that have grown in a fine-grained phyllitic matrix. |
| Typical nepheline-dolerites are scarce, and consist of idiomorphic augite, surrounded by nepheline. |
| Some quartz phenocrysts are very irregular in form, strongly corroded and embayed, others are idiomorphic with bipyramidal habit. |
| The augite is mostly a variety of diopside and is only occasionally idiomorphic. |
