Carmeltazite, ZrAl2Ti4O11, a new mineral trapped in corundum from volcanic rocks of Mt Carmel, Northern Israel
Abstract
<p>The new mineral species carmeltazite, ideally ZrAl<sub>2</sub>Ti<sub>4</sub>O<sub>11</sub>,was discovered in pockets of trapped melt interstitial to, or includedin, corundum xenocrysts from the Cretaceous Mt Carmel volcanics ofnorthern Israel, associated with corundum, tistarite, anorthite,osbornite, an unnamed REE (Rare Earth Element) phase, in a Ca-Mg-Al-Si-Oglass. In reflected light, carmeltazite is weakly to moderatelybireflectant and weakly pleochroic from dark brown to dark green.Internal reflections are absent. Under crossed polars, the mineral isanisotropic, without characteristic rotation tints. Reflectance valuesfor the four COM wavelengths (R<sub>min</sub>, R<sub>max</sub>(%) (λ in nm)) are: 21.8, 22.9 (471.1); 21.0, 21.6 (548.3), 19.9, 20.7(586.6); and 18.5, 19.8 (652.3). Electron microprobe analysis (averageof eight spot analyses) gave, on the basis of 11 oxygen atoms performula unit and assuming all Ti and Sc as trivalent, the chemicalformula (Ti<sup>3+</sup><sub>3.60</sub>Al<sub>1.89</sub>Zr<sub>1.04</sub>Mg<sub>0.24</sub>Si<sub>0.13</sub>Sc<sub>0.06</sub>Ca<sub>0.05</sub>Y<sub>0.02</sub>Hf<sub>0.01</sub>)<sub>Σ=7.04</sub>O<sub>11</sub>. The simplified formula is ZrAl<sub>2</sub>Ti<sub>4</sub>O<sub>11</sub>, which requires ZrO<sub>2</sub> 24.03, Al<sub>2</sub>O<sub>3</sub> 19.88, and Ti<sub>2</sub>O<sub>3</sub> 56.09, totaling 100.00 wt %. The main diffraction lines, corresponding to multiple hkl indices, are (din Å (relative visual intensity)): 5.04 (65), 4.09 (60), 2.961 (100),2.885 (40), and 2.047 (60). The crystal structure study revealedcarmeltazite to be orthorhombic, space group Pnma, with unit-cell parameters a = 14.0951 (9), b = 5.8123 (4), c = 10.0848 (7) Å, V = 826.2 (1) Å<sup>3</sup>, and Z = 4. The crystal structure was refined to a final R<sub>1</sub> = 0.0216 for 1165 observed reflections with F<sub>o</sub> > 4σ(F<sub>o</sub>).Carmeltazite exhibits a structural arrangement similar to that observedin a defective spinel structure. The name carmeltazite derives from MtCarmel (“CARMEL”) and from the dominant metals present in the mineral,i.e., Titanium, Aluminum and Zirconium (“TAZ”). The mineral and its namehave been approved by the IMA Commission on New Minerals, Nomenclatureand Classification (2018-103).</p>
