On the problem of transportability of kimberlite minerals relative to their source: The case of pyrope and picroilmenite

Rudy I Metally
Data on transportability of kimberlite minerals with increasing distance from their primary source are presented. It is argued that the degree of mechanical processing of kimberlite indicator mineral grains is the most reliable criterion for determining ...

Picroilmenites in Yakutian kimberlites: variations and genetic models [PDF]

Solid Earth, 2014
Abstract. Major and trace element variations in picroilmenites from Late Devonian kimberlite pipes in Siberia reveal similarities within the region in general, but show individual features for ilmenites from different fields and pipes. Empirical ilmenite thermobarometry (Ashchepkov et al., 2010), as well as common methods of mantle thermobarometry and ...

Picroilmenite from Kimberlite Pipes of Central Yakutia

IOP Conference Series: Earth and Environmental Science, 2020
Abstract Picroilmenite is one of the most important indicator minerals of kimberlite rocks, which can be used in solving petrological problems and in the search for diamond deposits. The present study shows the results of studying picroilmenite grains from the Manchary and Aprelskaya pipes within the Khompu-May kimberlite field (Central ...
