Located on altitude 2061 m in the middle flow of Aryskan-Astyg-Oi stream in 12 km NNE from Aksug copper deposit.
HREE-bearing albitites replacing alkaline syenite (more early intrusive phase) and granite (more later one) massif within diorite massif. Discovered in 1952 and researched in 1953-1959 by trenches and 3 levels of adits. REE+Y2O3 resources were estimated over 30000 t.
Here were made first finds of thalenite-(Y) and priorite on USSR territory.

443.8 - 541 Ma
|Cambrian-Ordovician plutonic rocks|
Age: Paleozoic (443.8 - 541 Ma)
Comments: Deep-seated to high-level intrusions are included. Many charnockites, anorthosites, and large ophiolites, classified as plutons, are distinguished in the database using the SIGNIF item. Ophiolites were classified as plutons, even where remnants may be extrusive and/or sedimentary.
Lithology: Plutonic rocks
