<title>Abstract</title>
<p>Numerous small octahedra of a black, brittle, magnetic mineral were found in calciphyre and brucite marble, occurring in the northern part of the exocontact zone of the Kondyor ultramafic-alkalic massif (south-eastern part of the Aldan Shield, 250 km north west of sea port Ayan). Their composition corresponds to the group from titanium magnesioferrite (11.53% TiO<sub>2</sub>) to titanium-rich magnesian spinel (27.34% TiO<sub>2</sub>), similar to spinellide found in Greenland (Gittins <italic>et al.</italic>, 1982) and in Iraq (Al- Hermezi, 1985) and approved by the Commission on New Minerals as a new mineral named qandilite. Hardness, specific gravity, and reflectance of Kondyor qandilite are similar to those of the Iraq mineral. Peaks of IR-absorption spectra are equal to 580&#x2013;590cm<sup>-1</sup> (<italic>&#x03BD;</italic><sub>1</sub>) and 431&#x2013;438cm<sup>&#x2212;1</sup> (<italic>&#x03BD;</italic><sub>2</sub>). There is a positive correlation between lattice parameters and the amount of Mg<sub>2</sub>TiO<sub>4</sub>: from 8.368 &#x00C5; at 26.6% to 8.429 &#x00C5; at 60.4%. Kondyor qandilite crystallized together with geikielite, oxidized alumina spinel (8.55% Fe<sub>2</sub>O<sub>3</sub>, f<sub>total</sub>= 16.5%), periclase, and forsterite.</p></abstract>
