Among their topics are experimental results on fractionation of the highly siderophile elements at variable pressures and temperatures during planetary and magmatic differentiation, nucleosynthetic isotope variations of siderophile and chalcophile elements in the solar system, the distribution and processing of highly siderophile elements in cratonic mantle lithosphere, chalcophile and siderophile elements in mantle rocks: trace elements controlled by trace minerals, petrogenesis of the platinum-group minerals, and highly siderophile and strongly chalcophile elements in magmatic ore deposits.
In stream sediment geochemical exploration, regardless of chemical pollution, the variation from the normal form has two syngenetic and epigenetic components; where the syngenetic component is related with petrogenesis and epigenetic component is related to economical mineralization that is known as the explorative useful component.
