Abstract

Clinopyroxenes from Peñas de Haya (Guipúzcoa, Navarra) have been studied by X-ray single crystal diffraction. From chemical and crystal structure refinement it is shown that these pyroxenes are almost pure hedenbergite. The unitiell dimensions are: a = 9.867(3), b = 9.052(4), c = 5.253(0) A, p = 104.89(2)".
