Abstract - Summary 
(short description):
Small scale dykes of cenotypal phlogopite minettes and Mn-Fe carbonatites were found in Early Bajocian Kushnarevski and Petropavlovski intrusives in Lozovskaya zone of crumpling in Highland Crimea. The dykes cross metamorphosed quartz gabbro-norite-dolerites and nests of prehnite, pumpelliite, gyrolite and laumontite among them. Carbonatites consist of Fe-Mn calcite, less kutnahorite, Mn-Fe dolomite, aegirine, Mn aegirine, magnesioarfvedsonite, Cu-Fe sphalerite, apatite-(CaCl,F), chalcopyrite, baddeleyite. Carbonatites are surrounded by a halo of fenites. Late formations of carbonatites are hematite, quartz, rhodochrosite, siderite, Zn alabandite, celsian, huttonite, monazite, circon, chlorite Ц brunsvigite, pyroxferroite, manganogrunerite, olmiite, Mn-holtstamite, galena. Rare miniveins of cinnabar cross aggregates of prehnite and laumontite, carbonatites and fenites.
Key words: Highland Crimea, minettes, Mn-Fe carbonatites, Mn aegirine, magnesioarfvedsonite, rhodochrosite, celsian, huttonite-monazite, alabandite, pyroxferroite.
