BIOSTRATIGRAPHY AND DEPOSITIONAL ENVIRONMENT OF SEKULIYE FORMATION OF GUYUK AND ENVIRONS, YOLA ARM OF THE BENUE TROUGH
Abstract
ABSTRACT
This study was carried out on Biostratigraphy and Deposition of Environment of
Sekuliye Formation of Guyuk and Environs, Yola Arm of the Benue Trough. This
research work was carried out in two main stages, field work and Laboratory
analysis. During the geologic field mapping exercise, the following equipment’s
were used, they include; Global positioning system (GPS), Compass
Clinometers, Geological Hammers etc. Laboratory analysis which is
Biostratigraphy method was used to determine the microfossils, during
Biostratigraphy method which include Disaggregation, Washing, Drying and
Picking. The Benthic foraminifera and Planktonic Ostracod are the two basic
species. Benthic foraminifera include the Orbitolina, Ammobaculites,
Haplophragmoide,and Cytherell And the Planktonic is Globigerinelloides. The
Sekuliye Formation is sequence of shale which mostly occurs in yellowish and
brownish in color inter- bedded with limestone. The limestone of this formation
occurs as fossiliferous, crystalline and fibrous in appearance. By studying
Benthic and Planktonic microfossils in sekuleye formation, researchers can gain
valuable insights into the geological history of the area and the earth’s past.
