Granite pegmatite. Quartz quarry, active 1882-1916, 50 x 5 m.

Notes on the mineral list:

— The type specimen of Åskagenite-(Nd) was found in a small pit near the Åskagen Quarry (collected at the beginning of the 20th century).

— Fibrous to thin-prismatic "lombaardite" overgrowing thalénite-(Y) from Åskagen is allanite-(Y), see https://www.mindat.org/min-32706.html

References:

ⓘ Allanite-(Nd) (TL)

Formula: (CaNd)(AlAlFe²⁺)O[Si₂O₇][SiO₄](OH)

Type Locality:

Description: Allanite-(Nd) forms fine grained aggregates, veinlets and black rims within limoriite-(Y). Allanite-(Nd) formed as a result of the alteration of thalenite-(Y); during this alteration, Y and HREE from thalenite were incorporated into limoriite structure, while LREE was incorporated into Allanite-(Nd) Sometimes, allanite-(Nd) forms individual crystals gradually changing in composition from allanite-(Nd) to Nd-epidote from axial to marginal zones of crystals.
