2015-9-1 · Limestone can be categorized as either high calcium or dolomitic. Pure high-calcium limestone is 100 percent calcium carbonate (100 percent calcite or aragonite). Generally, limestone of this purity does not occur naturally. High-quality, high-calcium limestone would actually contain 97 to 99 percent calcium carbonate and 1 to 3 percent impurities.

Most limestones are classified by Folk allochemical Rocks if they contain over l0% allochems (transported carbonate grains). Based on the percentage of interstitial material, the Rocks may be further subdivided into two groups: sparry allochemical limestones (containing a sparry calcite cement of clear coarsely crystalline mosaic calcite crystals) and microcrystalline allochemical …

V = K * i. (where V is the velocity of the groundwater flow, K is the hydraulic conductivity, and i is the hydraulic gradient). We can apply this equation to the scenario in Figure 14.5. If we assume that the permeability is 0.00001 m/s we get: V = 0.00001 * 0.08 = 0.0000008 m/s. That is equivalent to 0.000048 m/min, 0.0029 m/hour or 0.069 m/day.
