Little Lyakhovsky Island (Малый Ляховский: Maly Lyakhovsky) 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 km².
The Lyakhovsky Islands are named in honour of Ivan Lyakhov, who explored them in 1773.
Little Lyakhovsky Island consists of Upper Jurassic
to lower Cretaceous turbidites
, also known as "flysch
", covered by a thin veneer of Pliocene
to Pleistocene sediments
. These Mesozoic
rocks consist of sandstones
, 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
sandy and clayey sediments of colluvial
origin. Near the coast, the alluvial sediments grade into nearshore marine
sediments containing fossil
and lignitized wood. Thick permafrost
characterized by massive ice wedges has developed in these sediments.
Rush/grass, forb, cryptogam tundra covers Little Lyakhovsky Island. It is tundra consisting mostly of very low-growing grasses, rushes, forbs, mosses, lichens, and liverworts. These plants either mostly or completely cover the surface of the ground. The soils are typically moist, fine-grained, and often hummocky.
