feldspar

Latites contain plagioclase feldspar (andesine or oligoclase) as large, single crystals (phenocrysts) in a fine-grained matrix of orthoclase feldspar and augite.

The ore-hunting indicator is of calcite-potassium feldspar veins containing pyritohedron pyrite.

Therefore, the albitization of plagioclase is shown in the early stage of diagenesis and albitization of potash feldspar appears only in the late stage of diagenesis.

The middle oil-member is characterized by medium-sized sandstone and pebbled sandstone, with fair sorting and subangular sphaericity.Rock types mainly were feldspar debris sandstone.

The feldspar group contains tectosilicate minerals with similar properties, including orthoclase, albite and labradorite. Feldspars make up more than 60% of the upper crust of the earth.
