Read name silica covers an entire group of minereal, which have the general formual SiO_(2), the mole common of which is quartz. Quartz is form work silicane with SiO_(4) tetrahedra arranged in spirals. The spirals can turn in a clockwise or anticlockwise direction a feature that results in there being two mirror images, optically active, varieties of quartz. The silicate aion in the mineral kinotite is a Chian of three SiO_(4) tetrahedra that share corners with adjacent tetrahedra. The mineral also contains Ca^(2+) ions, Cu^(2+). ions and water molecule in a 1:1:1 ratio mineral is represented as
