Depositional Processes and Provenance Determi-nation Using Grain Size Analysis and Heavy Min-eral Assemblages of Surficial Sediment and Stream Sediment Samples from Iwere-Ile and Its Environs [ ]

The sedimentological study of surficial sediments (colluviums and stream sediments) was carried out around Iwere-Ile and its environs in part of southwestern Nigeria. Twenty-six (26) samples of which 11 were stream sediments and 15 were colluvial deposits were collected. The samples were subjected to grain size analysis and heavy mineral studies using standard procedures and the data obtained were subjected to statistical analysis from where the textural parameters and mineralogical characteristics were derived.
