The feldspar market has been segmented based on type into plagioclase feldspar and K-feldspar. These two types are categorized based on the inorganic minerals present in them.

For over a century, the origin of K-feldspar megacrysts in granites and granodiorites has remained an unresolved problem in igneous petrology. Traditionally, these megacrysts have been interpreted as ...

Determining what units these K-feldspars grew in and traveled through will help us figure out which magma chambers were connected at a given time and, therefore, how big magma chambers can get.

Feldspar first announced that it was creating this sensor-enabled track around 10 months ago – and that it could easily become the world leader in its field.

Feldspar can be classified into two forms, plagioclase feldspar and K-feldspar. Sodium and potassium are the two major minerals differentiating the types of feldspars.

The K-feldspar granodiorite dykes (B and C) are also located in a magnetic low and strong Cu soil anomaly area. Cu assay results from all K-feldspar porphyry outcrop samples are from 500-2,000 ppm.
