[1] Alpa Corral, El Talita and Los Cerros are the three largest individual plutons and together they make up the bulk of the batholith.
[1] The most common rock type is monzogranite with biotite and an igneous texture that is equigranular but varies from coarse grained to porphyritic.
[1] The relation of the magmatic episode represented by the Cerro Aspero Batholith to the Famatinian orogeny is not fully understood.
[1] Vertical to near-vertical veins of fluorite formed in the Cretaceous occur in the batholith.
Collectively these veins constitute the largest reserves of fluorite in the whole Sierras Pampeanas area.
