These skarns occur underlying a carbonate layer from the Lower Cambrian Bateiras Formation (BF) of the Douro Group, which is part of the Schist Greywacke Complex (SGC). This formation is divided into two members: an upper member characterized by the presence of grey phyllites and limestones; and a lower member characterized by greywackes containing a level of microconglomerates, followed by an alternation of greywacke with graphitic black phyllites.
Three major types of mineralized skarns can be distinguished for the São Pedro das Águias deposit as follows:
L Type – characterized by pink and green bands, fine to medium-grained with minor scheelite (0.5–0.6 vol%);
M Type – banded, medium to coarse-grained; with more abundant scheelite (0.8–3.6 vol%);
F Type – fine-grained, scarcely banded to massive, with scheelite (1.5 vol%), and abundant Sn minerals (3.1 vol%), namely malayaite that presents a green fluorescence under UV light.
The Barren skarns correspond to slightly banded, medium-grained, and fractured skarns that contain little to no scheelite but do contain some Sn minerals. They typically appear as clear layers interspersed within biotite schists.
