5.1.2. Dominase
The HCA for data from the Dominase area reveal two main groups of clusters of significance (Fig. 3). Group 1 is made up of PO43−, Mg2+, DO, pH, Na+, Cl−, and SiO2 which are derived from silicate mineral weathering and precipitation. Group 2 consists of TA, HCO3−, Ca2+ and K, and represents the weathering of calcite in the organic sediments.
