Reserves of barytes, fluorite, wollastonite and vermiculite have also been found. Wollastonite, lignite, and others. Sonora is the leading producer of gold, copper, graphite, molybdenum, and wollastonite. Grossular is found in contact metamorphosed limestones with vesuvianite, diopside, wollastonite and wernerite. Mineral resources such as limestone, marble, coal, silica, and wollastonite are abundant. Grossular is found in skarns, contact metamorphosed limestones with vesuvianite, diopside, wollastonite and wernerite. The minerals that accompany them are calcite, epidote, vesuvianite, garnet, wollastonite, diopside and amphibole. Industrial mineral production in Namibia includes salt, fluorspar, wollastonite and dimension stone. Therefore, minerals in soil such as anorthite or wollastonite have no time for nucleation-crystal growth. Mineral examples include plagioclase, microcline, rhodonite, turquoise, wollastonite and amblygonite, all in triclinic normal (). World reserves of wollastonite were estimated to exceed 100 million tonnes. Typical skarn minerals include pyroxene, garnet, idocrase, wollastonite, actinolite, magnetite or hematite, epidote and scapolite. Wollastonite (CaSiO) and enstatite (MgSiO) are examples of silicate-based minerals. Associated minerals include calcite, dolomite, grossular, wollastonite, talc, diopside, forsterite, cummingtonite, riebeckite and winchite. In an Austrian occurrence near Kloch, melilite, mayenite, wollastonite, kalsilite and corundum are found.
