| 1903 Mineral. Mag. 13 374 Following Rinne, E. Düll..proposes the terms ortho-pyroxene and klinopyroxene. 1963 W. A. Deer et al. Introd. Rock-forming Minerals II. 33 Many orthopyroxenes can be distinguished from clinopyroxenes by their characteristic pink to green pleochroism. 1967 H. H. Hess & A. Poldervaart Basalts I. 201 An increase in olivine and clinopyroxene in the alkali basalts (at the expense of plagioclase) leads to the development of melanocratic lavas. 2002 Jrnl. Petrol. 43 1620/1 The dykes generally consist of assemblages of clinopyroxene-biotite-plagioclase. |
