Copper (gold) ore body I and II that have been found are controlled by both surrounding rock and intermediate-acid rock and are generated in the skarns near the contact zone of quartz diorites
and marbles and the cracks of quartz diorite
This target area contains outcropping quartz vein stockworks with centerline magnetite-pyrite-chalcopyrite, which cut secondary biotite altered quartz diorite
4 Ma) vary in composition with time, from early diorite to quartz diorite
to late tonalite and post-mineral andesitic dykes.
The Dickie Brook pluton also consists of three units: leucogabbro to quartz gabbro, diorite to quartz diorite
and quartz monzodiorite to monzogranite.
The Ruby Range Batholith is a large plutonic complex which underlies the south and central portion of the claim group, locally composed of quartz diorite
, tonalite and granodiorite with lesser amounts of diorite, gabbro and granite.
The lithology of intrusive rocks consists of gabbro, diorite, quartz diorite
, granodiorite, biotite granite and leucogranite.
At the Tonglushan deposit, a typical representative of this type, quartz diorite
porphyries have intruded gypsum-bearing limestones of the Triassic-age Daye Formation.
Offset dikes consist of a rock called quartz diorite
that spread out from the Sudbury Basin like arteries.
Material mined from the Fennell Pit is mainly hard rock in the form of quartz diorite
and andesite which requires conventional drilling and blasting.
The composition of this intrusive varies from quartz monzonite through granodiorite to quartz diorite
The rock consists of both massive and foliated quartz diorite
