Maly Lyakhovsky Island (Russian: Малый Ляховский) is the second largest of the Lyakhovsky Islands belonging to the New Siberian Islands archipelago in Laptev Sea in northern Russia. It has an area of 1,325 square kilometers (512 sq mi).
The Lyakhovsky Islands are named in honour of Ivan Lyakhov, who explored them in 1773.
Maly Lyakhovsky Island consists of Upper Jurassic to lower Cretaceous turbidites, also known as flysch, covered by a thin veneer of Pliocene to sediments. These Mesozoic rocks consist of sandstones, argillites, and shales deformed into east-northeast striking folds about 7 to 20 km wide. The Mesozoic rocks are covered by a relatively thin layer of Pliocene to Pleistocene sandy and clayey sediments of colluvial and alluvial origin. Near the coast, the alluvial sediments grade into nearshore marine sediments containing fossil marine mollusks and lignitized wood. Thick permafrost characterized by massive ice wedges has developed in these sediments.
