Abstract

Detrital plagioclase (An₁₂-An₂₈) has been partially to completely albitized during burial diagenesis depths of about 2500-3000 m; 75-100°C present temperature). Some of the microporosity within the albite pseudomorphs is caused by volume reduction during albitization of the detrital plagioclase. The amount of albite formed in the pseudomorphs is related to the molar proportion of albite component in the detrital unstable Ca-rich plagioclase. -Authors
