1. a group of silicate minerals with chain-like crystal structures similar to pyroxenes but with different chemical compositions
Usage: geology; mineralogy

Examples

• The geologist identified several pyroxenoid minerals in the metamorphic rock sample.
• Wollastonite is a common pyroxenoid found in contact metamorphic zones.
• Pyroxenoid minerals differ from pyroxenes in their silicate chain arrangements.
• The laboratory analysis revealed the presence of pyroxenoid crystals in the specimen.
• Students learned to distinguish between pyroxene and pyroxenoid mineral groups.
• The pyroxenoid structure contains single chains of silicate tetrahedra.
