How To Use rhombohedral In A Sentence
- Like hematite, some goethite is pseudomorphic after a rhombohedral carbonate mineral.
- Thus. it is clear that at one point in the history of these specimens they appeared as normal quartz crystals perched upon a matrix of rhombohedral carbonate, likely dolomite.
- The calcite formed scalenohedral and rhombohedral crystals on some of the quartz crystal groups.
- No evidences of low-temperature phase transition were found for PbTiO3, while the tetragonal-orthogonal and orthorhombic -rhombohedral phase transitions were present for BaTiO3.
- The calcite formed scalenohedral and rhombohedral crystals on some of the quartz crystal groups.
- In the gold/pyrite ore, it occurred as sharp, cloudy white rhombohedral crystals to 3 mm in size; tennantite and tetrahedrite were typically crystallized on the calcite.
- At the Kingston mine, calcite occurred as thin massive veins cutting the lode and as modified rhombohedral crystals to 7 mm with inclusions of cuprite and chalcocite.
- In addition, poor-quality, translucent to cloudy, dark gray cordierite is also present, as is corundum with well-developed rhombohedral parting that tends to crumble.
- Like hematite, some goethite is pseudomorphic after a rhombohedral carbonate mineral.
- This insulin hexamer corresponds with the unit cell in the rhombohedral crystals first investigated and is the asymmetric unit in the monoclinic form which appears in the presence of phenol. Nobel Lecture The X-Ray Analysis Of Complicated Molecules
