Rock Textures - Geology for Today - Dr. Tambra L. Eifert

Metamorphic rocks with non-foliated texture typically undergo minimal deformation and the parent rocks are composed of minerals that exhibit equidimensional crystals, such as calcite or quartz. The parent rock from which marble forms through metamorphism is limestone. Limestone is composed of calcite (calcium carbonate).

2013-8-31 · To initiate dosing, first adjust calcium and alkalinity to roughly their correct ranges. This may require a substantial dose of just the calcium part if calcium is low (e.g., below 380 ppm). I would suggest targeting calcium between 380 and 450 ppm, and alkalinity between 2.5 and 4 meq/L (7-11 dKH; 125-200 ppm calcium carbonate equivalents).
