Description

The study is restricted to the occurence of three lines of beachrocks located between the Maracaipe river and Sirinhaem river, southern coast of Pernambuco state. The mineralogy and petrography, made it possible the characterization of three types of cements (micrite envelope, acicular crust and intergranular cryptocrystalline). They correspond to diagenetics microfacies which are set in different diagenetics environment. X-ray analysis, as well as sup(13)C/ sup(12)C e sup(18) O/ sup(16) O isotope analysis, show evidence of a dominantly marine precipitating fluid with a subordinate fresh water influence on a second cement generation.
