Mineralogical And Geochemical Study of Andesite Alteration Zone in Bukit Mantri Gold Mine, Balung, Sabah

This paper highlights the geochemical compositions and mineralogy of the alteration zone of the andesitic host rock and volcanic breccia in Bukit Mantri area near Balung, Tawau, Sabah, where a gold mining project is now taking place. Minerals identified by XRD analysis include quartz, pyrite, K-feld...
