DETERMINATION OF THE SEDIMENTOLOGICAL AND GEOCHEMICAL CHARACTERISTICS OF THE SEDIMENT IN THE NIGER DELTA BASIN
CHAPTER ONE INTRODUCTION The mineralogical and chemical composition of clastic sedimentary rocks are controlled by various factors, including (1) the composition of their source rocks, (2) environmental parameters influencing the weathering of source rocks (e.g., atmosphericchemistry, temperature, rainfall and topography), (3) duration of weathering (4)transportation mechanisms of clastic material from source region to depocenters, (5)depositional environment (e.g., marine versus fresh water), and (6) post-depositional processes (e.g., diagenesis, metamorphism) (Hayashi et ...
