This study investigates the paleoenvironment and hydrocarbon potentiality of mid-upper Cretaceous and late Eocene-early Oligocene sediments from two southern Nigerian inland basins. Therefore, palynological and palynofacies analyses were carried out on 15 outcrop samples from Calabar Flank and 112 ditch-cutting samples from Dahomey Basin. The st...
Article
: Detailed palynological and palynofacies studies of ditch cuttings samples from ML‑1 well, Niger Delta, were carried out to construct a stratigraphic scheme. The palynofloral assemblage is quantitatively dominated by mangrove and brackish to freshwater swamp taxa with moderate abun‑ dance of Monoporites annulatus. Botryococcus braunii was common...

The relatively low energy conversion efficiency of dye-sensitized solar cells (DSSCs) is a key challenge hindering the commercialization of the solar cell. The photochemical performance of the dye used as a photosensitizer for the DSSC greatly determines the efficiency of the solar cell. This study demonstrates the suitability of dye extracted from...

Phytochemical analysis of Macrosphyra longistyla leaf, stem bark, and root extracts revealed different constituents. The GC-MS analyses of their ethanolic extracts showed the presence of bioactive compounds: the stem bark yielded 9 compounds, such as squalene, vitamin E, and fatty acids; the root extract revealed 10 different compounds, especially...

This paper presents a sequence-stratigraphic interpretation from the lithologic data and palynological and palynofacies analyses of four shallow boreholes (Badore-1, Epe-1, Ikoyi-1, and Olokonla-1) within the upper Eocene-lower Oligocene interval of the Dahomey Basin. Three lithofacies, namely sandstones, shaly sands, and sandy shales were delineat...

Honey is a popular product consumed for its health benefits. It is an effective antimicrobial an antioxidant agent. Globally, palynological and chemical methods are among the means of authenticating honey quality, geographical origin and floral origin. Six honey samples from six Nigerian towns (Abi, Ikom, Lokpanta, Nsukka, Okigwe and Shaki) were su...

Introduction The emerging role of non-albicans Candida species (NACS) as causal agents of mild to life-threatening mycoses is increasingly being appreciated. Some NACS are known for intrinsic resistance or reduced susceptibility to some antifungal drugs. To inform therapeutic options and management of candidiasis, we embarked on Candida species sur...

Environmental air often contains airborne biological particles which are collectively called bioaerosols. These biological materials are released into the air through various anthropogenic and natural activities, and may contain viable and nonviable microorganisms, their fragments, spores or byproducts. Due to their role as potential sources of tox...

Alchornea laxiflora belonging to the Euphorbiaceae family has ethnomedicinal applications as antimalarial, anti-inflammatory, and anti-microbial agent. This present study investigated the spectroscopic, antibacterial, and toxicity profile of essential oil of Alchornea laxiflora (ALEO). The composition of ALEO was detected using Gas Chromatography-M...

There have been disparities about the age of the Eze-Aku Formation, Anambra Basin south eastern Nigeria. Eleven surface samples of the Eze-Aku Shales from the River Obey in Umudi village, Lokpanta Abia state were subjected to standard palynological, palynofacies, kerogen preparation and analysis. A diversified palynoflora with preponderance of typi...

A palynological study of recent sediments from Ijora Creek, an Urban Creek in Lagos, Southwestern Nigeria was carried out to provide inferences on paleovegetation and climate change over time in the study area. Two stations 90m apart were sampled at low tide in a boat using a Russian peat corer. Samples were taken at 10cm intervals and eighteen sed...

Depositional environments of sedimentary clay play a significant impact on the industrial applications of clay. Palynological technique was used to analyze thirteen outcrop samples to reconstruct depositional environment and assign age to the Ezinachi Kaolinitic Clay Deposit, Southeastern Nigeria for the first time. The palynological analysis revea...

The need to increase our knowledge of palaeo-flora is important in palaeoclimatic and palaeoenvironmental reconstruction of the Tertiary Niger Delta as to highlight possible changes in the depositional environments over time. Hence, palynological data from the M1well from the western Niger Delta region were employed in an attempt to reconstruct the...
Article
The graphic correlation method provides better and higher resolution to the stratigraphic problems than zonation biostratigraphy. The measured total stratigraphic ranges of 44 palynomorphs present in five wells from the Niger Delta Basin have been assembled by graphic correlation method into a chronostratigraphic framework. The analysis by graphic...

A multi-proxy study of an offshore core in Saldanha Bay (South Africa) provides new insights into fluvial deposition, ecosystems, phytogeography and sea-level history during the late Paleogene-early Neogene. Offshore seismic data reveal bedrock topography, and provide evidence of relative sea levels as low as -100 m during the Oligocene. 3D landsca...

There is a dire need to assess the petroleum-generating potential of the Nigerian inland basins. The Nigerian Federal Government has in the last few years demarcated the inland basins, of which little is known palynologically, for oil and gas exploration activities. An input from Nigeria concerning events of the Cretaceous-Paleogene boundary would...

The seepage of bitumen, a natural resource found in abundance in the Nigerian Dahomy belt is gradually becoming a source of concern due to contamination of surface waters and soil. Developing microbial strains that could be useful in restoring contaminated environment is therefore needful. This work was carried out to isolate and identify bacterial...

Various species of Pteridophytes and Bryophytes abound in the Nigerian Neogene as revealed by palynomorph records. One of the commonest is Sphagnum species with spores which are normally with smooth exine (Stereisporites spp.), which are of three types. These appear to have evolved close to the Early Late Miocene much before those with varied sculp...

For effective zonation, paleoenvironmental interpretation and correlation of well sediments, there is need for moderate recovery of palynomorphs. This is of utmost importance in the Niger Delta where the existing zonation schemes are built on such evolutionary parameters as Quantitative Tops, Quantitative Bases, Base Rich, Top Rich occurrences of t...

Biostratigraphy is a very useful tool in exploration and production among other disciplines. Reports abound in different parts of the world highlighting the use of dinoflagellate cysts abundance and diversity peaks apart from foraminiferal and nannofossil data in stratigraphic age delineation. Appreciable numbers of well preserved dinoflagellate cy...
