【 摘 要 】

The authors consolidated disparate information about sapphirine-bearing rocks of the Urals. It is shown that they belong to genetically different entities. There are the intrusive rocks (hornblendites, gabbros), bodies of eclogites and eclogite-lyke rocks, high-metamorphizied Paleozoic bauxite (emery rocks). Given the most complete petrographic and mineralogical characteristics the corundum-bearing sapphirine-spinel hornblendites which compose clastolithe blocks in lenses of serpentinite melange among Kyshtim suite gneisses of the Il’meno-Vishnevogorsky complex. For the first time the data of X-ray, Mössbauer and Infrared spectroscopy of sapphirine from the hornblendites, chemical compositions of most minerals in the rocks are given. The conclusion about the magmatic origin of the sapphirine-spinel hornblendites of the Urals is made.
