A. B. Shepel, M. E. Gavrilenko, V. P. Lepilin
Geotectonic position and geological structure of the Leglier-Timpton ore belt (Aldan Shield), stretching over 280 km and controlling the placement of magnetite, phlogopite-magnetite and phlogopite deposits of an ancient magnesian-skarn formation are examined. The ore belt endogenous megazoning, consisting in regular changing along its strike and in vertical section of ore-bearing zones possessing various ore specialization is characterized. The paper also contains a supposition concerning the crucial role of mantle fluids in the formation of genetically related and formationally united deposits of the Leglier-Timpton ore belt within the Aldan Shield.
Key words: Aldan Shield, Leglier-Timpton ore belt, ore-bearing zones, megazoning, deposit, nonlinear metallogeny, mantle fluids.
