: Data on refractive indices, optic axial angles, and density, often correlated with chemical composition.

This volume covers minerals where silica tetrahedra are linked into infinite single chains. The primary subjects include: Rock-forming minerals, Volume 2,Deel 1

: Key tests and characteristics to differentiate similar minerals under a microscope. : Data on refractive indices, optic axial angles,

: Discussion of the mineral's occurrence and stability in igneous, metamorphic, and sedimentary environments. Key Data & Significance : Discussion of the mineral's occurrence and stability

: Each chapter begins with a data summary and a sketch showing optical orientation or stereographic projections.

(often cited as Volume 2A ) is a definitive reference work by W.A. Deer, R.A. Howie, and J. Zussman (DHZ). The second edition, published in 1978 and reprinted by the Geological Society of London , focuses exclusively on Single-Chain Silicates , primarily the pyroxene group. Core Focus: Single-Chain Silicates

: Includes minerals like wollastonite, rhodonite, and bustamite.
