They composition is calcite called “la calera” that is a Colombian term for areas where the soil is rich in limestone. The limestone is a sedimentary rock mainly composed for calcium carbonate (CaCO3), usually calcite and some traces of magnesite (MgCO3) among other carbonates. It may also contain small amounts of minerals such as clay, hematite, siderite and quartz.
The spring is free of microorganisms and has a unique characteristics in terms of mineralization with a significance level of silica.
