batholith

Nearby, the Yeoval Batholith to the northeast is spatially and genetically associated with Cu-Au-Mo mineralisation.

Historical work at Eagle by Noranda and others outlined a 3 km long trend of copper mineralization near the southern margin of the Hogem batholith. Reconnaissance mapping and rock sampling completed in 2019 by Arcwest focused on delineating higher grade lenses over 2.7 km of the mineralized trend.

The granite of Kumrat area, upper Dir belongs to Kohistan Batholith is sub-equigranular to in-equigranular, coarse to medium grained.

Within the Lower Volcanic Complex, we identify a Late Cretaceous volcanic succession (~77 to 69 Ma) correlative with the Tarahumara formation from southern Sonora and coeval with the San Ignacio batholith exposed to the west.

Three main geological units lie in the area of El Vapor district, (Fig 1): (i) San Lucas quartz-feldspathic gneisses (Gonzalez, 2001), which contains lenses of amphibolite and marble and are Proterozoic (Feininger et al., 1972); (ii) Segovia batholith of Jurassic age (160 [+ or -] 7 M.a., K/Ar in hornblende, Feininger et al., 1972), consists of a diorite with textural and compositional variations of quartz diorite and locally hornblende gabbro; and finally, (iii) Segovia sedimentary rocks in the west of Segovia mainly composed of black shales interbedded with siltstones, sandstones and intraformational conglomerates, which in the north of the area have been dated between the upper Aptian and the lower Albian (Feininger et al., 1972) based on macro-fauna dating.

The Silurian (Ludlovian to Pridolian) to Late Devonian (Famennian) Saint George Batholith in southwestern New Brunswick is a large composite intrusion (2000 [km.sup.2]) that was emplaced into the margin of the peri-Gondwanan microcontinent of Ganderia (Fig.
