In his early works, he studied the geology of the Kama region: "Essay on the geological structure of the environs of Solikamsk" (1888), "On the question of the conditions for the occurrence of the Kama salt-bearing strata" (1908) and others. He theoretically substantiated the existence of the Pechora coal basin.
