Over 500 refereed scientific publications, in 32 languages, mostly in cognitive epistemology and palaeoart studies, also general and replicative archaeology, soil science, speleology, deontology, semiotics and geomorphology. In all about 1,210 publications, including several books. Starred in several film documentaries. About 65 papers presented at professional meetings and invited lectures, over 535 interviews by printed and electronic media, in many parts of the world.
In various thematic and geographical areas: especially in central, northern, eastern, western and southern Europe; Siberia, India, China, Canada, USA, Mexico, Caribbean, various South American countries, southern Africa, Morocco, all regions of Australia.
Innovations: first in the world to date rock art directly with radiometric methods (reprecipitated carbonates in Malangine Cave, Australia); developed first non-interfering rock art dating method (microerosion method, first applied at Lake Onega, Russia); introduced advanced statistics in Australian archaeology (Brainerd-Robinson method). Developed new techniques for assessing weathering of silica minerals, and for studying cave climate; invented an instrument to measure the porosity of rock; conducted first comprehensive study of wall markings in caves. Responsible for major scientific discoveries in various countries, including oldest known rock art in the world, first Palaeolithic art of China, most cave art of Australia. Founded Archaeological Soil Lab in 1980, Archaeological Publications and AURA in 1983, and co-founded IFRAO in 1988. Campaigned actively for Aboriginal control of sites of indigenous heritage.
