Andradite

specimen number:
2341213

location:
Ighrem, Imilchil, Midelt, Draa-Tafilalet, Morocco

description:

Brown mostly lustrous sharply formed crystals of andradite measuring to 2.0 cm in size across the top of matrix. In good condition and crystallized all around. The specimen comes with a previous label from the collection of Jan Erik Larsen.<p.Situated in the High Atlas Mountains within the Draa-Tafilalet Region of Morocco, the Ighrem area near Imilchil features complex Mesozoic sedimentary rock formations intruded by basaltic and gabbroic igneous rocks. Late-stage contact metamorphism and skarn mineralization within these igneous-sedimentary contact zones led to the formation of high-quality garnet group minerals. Mined primarily by local artisanal miners in recent decades, the locality is known for producing good andradite.
