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.
Geology
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,
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.
Vegetation
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.
