Abstract
The stable isotopes in conjuction with petrography and whole rock geochemistry of carbonates from the Ukhrul area of the Manipur Ophiolite Complex were examined to understand their depositional environment. These carbonates are characterized by the presence of biomicrite as dominant microfacies, high CafMg ratio (13.99 to 121.69), low phosphorous content (0.00 to 1.51), absence of oolites and benthic foraminifera. They show depleted values of 5UC%o (0.89 to 2.74) and 6"O%o (-8.50 to-l 0.5). The data obtained from the petrographical and geochemical investigations suggest that these carbonates were formed in a shallow marine environment (neritic to bathyl).
