Özet
AçıklamaBarytocalcite 1.png
English: Illustration from 1911 Encyclopædia Britannica, article BARYTOCALCITE.
The crystals belong to the monoclinic system and are usually prismatic or blade-shaped in habit. The hardness is 4, and the sp. gr. 3.65. There are perfect cleavages parallel to the prism faces inclined at an angle of 73° 6′, and a less perfect cleavage parallel to the basal plane, the angle between which and the prism faces is 77° 6′; the angles between these three cleavages thus approximate to the angles (74° 55′) between the three cleavages of calcite, and there are other points of superficial resemblance between these two minerals. Chemically, barytocalcite is a double salt of barium and calcium carbonates, BaCa(CO3)2.
