“…In contrast, the majority of the supra-Moho chromitites are Al-rich and characterized by a variable content of TiO 2 (0.15 wt % to 0.8 wt %). Confirming the previous work by [8,[14][15][16][17]21], the composition of the Alapevsky chromite indicates the coexistence of the Al-rich and Cr-rich chromitites, a common feature of many ophiolitic belts worldwide [22,[36][37][38][39][40][41][42][43][44][45][46][47][48][49][50].…”

“…Alchromite suggest that the Cr-spinel crystallized through high degrees of partial melting at the shallowest levels of an upper mantle source (within the Moho Transition Zone), i.e., close to the layered gabbro sequence (e.g. [60][61][62][63][64][65]). Trace element enrichment of Cs, Rb, Pb, Sb, Sr are caused due serpentinization process, tremolite and/or carbonate precipitation also caused Pb, Sb enrichment and produces in serpentinites (cf.…”

“…Современные исследования в области ремоби-лизации ЭПГ свидетельствуют о подвижности тугоплавких ЭПГ в измененных хромититах [Garuti, Zaccarini, 1997;Melcher et al, 1997;Proenza et al, 1999;Ahmed, Arai, 2003;Tolstykh et al, 2009]. Формы выделений и ассоциации высоко-и низкотемпературных минералов позволяют предполагать вторичное происхождение (в ходе низкотемпературных постмагматических процессов) таких ассоциаций: гарутит (Ni,Fe,Ir), закаринит (RhNiAs), (Ir,Ni,Cu)S 3 , Pt-Cu, (Pt,Cu,Fe,Ni), (Cu,Pt,Pd), Rh 2 CuSn, (Pt,Cu,Sb).…”
