Abstract
Hydroxylchondrodite was found in the Perovski� tovaya Kop’ on the western slope of the Chuvashskie Mountains in the Zlatoust region of the Southern Urals (Russia). It is located in the contact zone between magnesium skarn and host marble being intergrown in aggregates composed of calcite and cli� nochlore with dependent amounts of dolomite and tremolite. Among the other minerals are diopside, garnet of the andradite–grossular row, magnetite, per� ovskite, hydroxylclinohumite, and titanite. Hydroxyl� chonrodite occurs as coarsely formed tabular or lens� like individuals with sizes up to 0.5 × 1.5 × 1.5 cm and their intergrowths up to 2 cm. Thin polysynthetic twinning by {001} is observed under the microscope; the thickness of twin lamellas is usually ~1 µm, rarely up to 5 µm. The mineral is semitransparent, reddish
