Scientific interests and investigations
Mineral-forming processes in post-magmatic stage: reconstruction of the
mechanisms and physico-chemical conditions of the origin of secondary feldspars
(albite and adularia) at the expense of the primary plagioclases; relations
between the crystallisation kinetics of the hydrothermal feldspars and ordering
of their structure.
Experimental modelling
of the secondary feldspar formation at the expense of the primary feldspars in
carbonate solutions; the problem of the secondary post-plagioclase albite and
secondary adularia.
Kinetics of changes of
the feldspar ordering and homogenisation of the exsolved feldspars from
xenoliths in lavas.
Experimental studies of
the alkali feldspar crystallisation rate from hydrated magmatic melts bearing
fluorine.
Experimental
decomposition of plagioclase in carbonate aqueous solutions; origin of the
zeolite-type structures under variable kinetic conditions; studies of the water
position in the zeolite-type structures by means of several spectroscopic
methods.
