THE APPLICATION OF INFRA-RED ABSORPTION SPECTROSCOPY TO CARBONATE MINERALOGY

Authors


Abstract

The data given in the literature for the infra-red identification of carbonate minerals is summarised, and a technique is described which may be used to identify magnesite, smithsonite, dolomite, rhodochrosite, calcite, aragonite, strontianite, cerussite and witherite by means of their infra-red absorption bands. Two quantitative applications of the use of infra-red spectroscopy are considered and techniques are outlined for the determination of calcite-dolomite ratios in carbonate rocks, and calcite-aragonite ratios in shell material.
