GEOCHEMISTRY OF ALKALINE SPRINGS AND ULTRAMAFIC TO MAFIC ROCKS IN BOTOLAN, ZAMBALES: SIGNIFICANCE TO CARBON SEQUESTRATION
Abstract
High concentrations of atmospheric carbon dioxide (CO2) today led to the development of carbon capture and storage (CCS) technology, which is based on the concept of mineral carbonation in peridotites, enabling CO2 sequestration. In the Philippines, several opportunities for CCS in ophiolites and associated springs are yet to be studied. Therefore, this paper examined the geochemistry of alkaline springs and ultramafic to mafic rocks in Botolan, Zambales and determined its significance to carbon sequestration. Results showed that the water is mainly composed of Mg, Ca, and HCO3, which is a characteristic of Type I Mg2+ - HCO3 - rich waters. Saturation index modelling revealed its supersaturation with dolomite, calcite, aragonite, and magnesite, with the latter two verified to be present in the area. Major whole rock chemistry showed that three samples were ultrabasic (37.23-40.66 wt% SiO2) while one was basic (51.76 wt% SiO2). Depletion in K2O, MgO, and CaO in the rocks and enrichment of Mg, HCO3, and Ca in the springs were due to mineral dissolution. Meanwhile, serpentine weathering induces mineral carbonation. These results are significant to carbon sequestration since a higher percentage of magnesite are expected to precipitate with more CO2 introduced. This suggests that Poon Bato has a promising storage medium for further carbon sequestration.
