• EXPERIMENTAL STUDY OF FE-MG DISTRIBUTION BETWEEN BIOTITE AND ORTHOPYROXENE AT P=490 MPA 

  FONAREV V.I.; KONILOV A.N. (1986)

  Partitioning of Mg and Fe between coexisting biotite and orthopyroxene has been experimentally determined at temperatures 700, 750 and 800° C and 490 MPa total pressure in the system KAlO2-MgO-FeO-SiO2-H2O. Oxygen fugacity ...
• EVALUATION OF THE ECONOMIC POTENTIAL OF GOLD DEPOSITS BY THE ANALYSIS OF OXIDIZED ORE OUTCROPS AND EXOGENIC AUREOLS: METHODS USE IN THE U.S.S.R 

  ROSLYAKOV N.A.; ROSLYAKOV N.V. (1986)

  In the majority of cases, new auriferous deposits, including some which are unique, are being discovered in regions with, at the most, only a thin allochthonous (transported) cover and this trend is likely to continue. ...
• THE VENDIAN SYSTEM OF SIBERIA AND A STANDARD STRATIGRAPHIC SCALE 

  KHOMENTOVSKY V.V. (1986)

  In Siberia Vendian is equated with a Yudoma Complex or Yudomian. Yudomian deposits of the Siberian Platform and adjacent geosynclines differ greatly in facies and thickness. According to the composition and structure of ...
• EVOLUTION OF ARCHAEOCYATHS AND PALAEOBIOGEOGRAPHY OF THE EARLY CAMBRIAN 

  ZHURAVLEV A.Y. (1986)

  In the Early Cambrian, there were two peaks of the increase in number of new archaeocyathan genera. These diversification bursts are, perhaps, related to significant changes in Early Cambrian palaeogeography. The first ...
• TECTONICS AND PALEOMAGNETISM OF STRUCTURAL ARCS OF THE PAMIR-PUNJAB SYNTAXIS 

  BAZHENOV M.L.; BURTMAN V.S. (1986)

  The Pamir-Punjab syntaxis consists of two structural arcs with the crests facing northward—the Pamir and Hindu-Kush-Karakorum arcs. These arcs are mutually disharmonious, and the exterior (Pamir) arc is more tight, as ...
