The Adamello massif is a mountain range
in the Italian Alps, located in the provinces of Trento (Adamello-Brenta) and Brescia; it is
a protected area, under the two different provinces (the
two green areas on the picture) and, today, minerals
search is strictly forbidden.
The nucleus of the Group is a plutonic intrusion made of granite rocks (granodiorite; tonalite around the nucleus).
A lot of minerals are found in the metamorphic rocks, the older calcareous
formations transformed by the magma intruding, cooling down and consolidating |
