Abstract
Carbonate rock are sedimentary rock that contained carbonate mineral such as calcite, dolomite and aragonite. Limestone (calcite) and dolostone (dolomite) are two main carbonate rocks. Perlis is made up of continuous succession of Paleozoic rock, which are Machinchang Formation, Kubang Pasu Formation, Setul Group, Chuping Formation and Quaternary alluvium (Jones, 1983). Carbonate rocks are found in Setul Group and Chuping Formation. In Perlis, new location of these carbonate rock formations was discovered (Lee, 2001; Harun and Jasin, 2000). In this study, geochemistry method (XRD) is used to characterize carbonate rock at the new site. The findings show that Setul Group’s carbonate rock consist of ankerite while Chuping Formation’s carbonate rock consist of calcite and dolomite with high quartz content. Presence of ankerite depicts the rock underwent a very high temperature during its lifespan.
