  A Pb, Sr and Nd isotope study of the basement and …

  1991111 · Abstract Combined Pb, Sr and Nd isotope determinations on several Nigerian Mesozoic ( 170 Ma) ring complexes, studied previously by van Breemen and co-workers, indicate a multistage petrogenetic process. Mantle-derived differentiated magmas assimilated crustal basement of average Early Proterozoic age. After crystallisation, some …

  201861 · Host rock – baryte contact at Bunde reveals proximal wall-rock alteration. Epidotization is vivid and more intense at Bunde. According to Paradis et al. (1998) the minimal nature of wall-rock modification obviously points to low thermal conditions that prevailed during precipitation from hydrothermal fluids.
