WebIn its crystal form, aragonite tends to have needlelike crystals and lacks calcite’s rhombohedral cleavage. In massive form, it is difficult to distinguish the two minerals in the field, as both react vigorously with cool dilute acid. Calcite is the more stable form and is far more abundant, and aragonite tends to convert to calcite over time. WebThe pyroxene group includes minerals that form in both the orthorhombic and monoclinic crystal systems. Orthorhombic pyroxenes are referred to as orthopyroxenes, and monoclinic pyroxenes are called clinopyroxenes. The essential feature of all pyroxene structures is the linkage of the silicon-oxygen (SiO4) tetrahedrons by sharing two of the …
