Copper-bearing schist (likely bornite/chalcopyrite ore)

Micaceous schist with sulfide minerals, chiefly bornite (Cu₅FeS₄) and/or chalcopyrite (CuFeS₂)

Coarse-grained granite

Granitic plutonic rock; chiefly quartz, alkali feldspar, plagioclase, biotite/hornblende

Quartz-rich rock, likely chert or chalcedony

Microcrystalline silica (SiO₂), possibly quartz/chalcedony

Coarse-grained mica-bearing metamorphic rock, likely schist

Mica schist, probably muscovite–biotite schist with quartz and feldspar

Granite

Coarse-grained granitic rock, chiefly quartz, alkali feldspar, plagioclase, and biotite/hornblende

Likely weathered basalt or mafic volcanic rock

Basalt; chiefly plagioclase feldspar, pyroxene, and possibly olivine

Fossiliferous limestone

Calcite-rich limestone (CaCO₃), containing possible fossil or peloidal inclusions

Pegmatitic granite

Granite, quartz–feldspar–mica assemblage

Likely basalt with a pale mineral-filled vesicle

Vesicular basalt, probably containing calcite or zeolite (uncertain from image)

Possible basaltic rock or meteorite candidate

Likely vesicular basalt; meteorite identification cannot be confirmed visually

Pegmatitic granite (quartz–feldspar–mica rock)

Granitic pegmatite; primarily quartz (SiO₂), alkali/plagioclase feldspar, and minor mica, with iron-oxide staining

Tumbled polymict breccia (probable quartz-rich breccia)

Clastic breccia composed mainly of quartz, feldspar, and iron-oxide-stained rock fragments
