The Anabar Plateau (Russian: Анабарское плато) is a mountain plateau in Krasnoyarsk Krai and the Sakha Republic (Yakutia), Siberia, Russia.
The plateau is in a latitude dominated by permafrost. The permafrost thickness under the Anabar Plateau reaches 1,400 metres (4,600 ft).[1]

Geology
The Anabar Plateau of the Central Siberian Plateau is one of the oldest structures on Earth, with rocks that are more than 3 billion years old. In its central region it is composed of Archean crystalline schists and gneisses.[5] Along the periphery of the plateau Proterozoic and Lower Paleozoic limestones predominate.[1]
