Petrographic and geochemical studies were undertaken on the Paleocene-Eocene limestones of the Ewekoro Formation in order to infer the depositional and post-depositional imprints on the limestone.
Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone has long …
The studied area lies between longitudes 5o22` to 5o40`E and latitude 7o42` to 7o55`N within the Ohafia-Ozuabam-Arochukwu areas of southeastern Nigeria (Fig. 1). Limestone is a sedimentary rock composed largely of the mineral calcite (CaCO 3), which is formed either by organic or inorganic processes (Serra 2006). It is
The most widely adopted method of limestone mining is through opencast pits with bench formation. Limestone mining causes …
Late Maastrichtian to Danian limestone of Nsukka Formation in Ohafia and its environs were studied to understand the geological processes that affected the rock after its deposition.
They include limestone, dolomite, marble, kaolin, barite, diatomite, feldspar, quartz and silica sands, gypsum, talc, silimanite, kyanite, phosphate, salt and bentonite. Limestone is widespread in the sedimentary basins of Nigeria. It is used extensively in cement production, as flux and refractory material, metallurgical applications etc.

Limestone occurs in most of Nigeria's sedimentary basins, and is used as a major r aw mater ial for cement manufacture in Ogun, Cross River, Benue,
The study area is the limestone deposit at Obajana in Kogi State, Nigeria which is within longitude 6020'E and 6028 'E and latitude 7 048 N and 7 56'N. Figure 1 shows the location map of the study area. The rock type in the study area includes schist, pegmatite, quartz, limestone, granite and granulites. The
Imports In 2022, Nigeria imported $2.96M in Limestone, becoming the 30th largest importer of Limestone in the world. At the same year, Limestone was the 670th most imported product in Nigeria . Nigeria imports Limestone primarily from: Turkey ($2.43M), China ($230k), Denmark ($161k), Spain ($128k), and Indonesia ($3.5k).
Limestone is a sedimentary rock primarily composed of calcium carbonate (CaCO3) in the form of mineral calcite or aragonite.It is one of the most common and widely distributed rocks on Earth, with a wide range of uses in various industries and natural settings. Limestone forms through the accumulation and compaction of marine …
Mining and quarrying are the processes of extraction of naturally occurring stone or minerals such as coal, ores, crude petroleum and natural gas from the earth. In Nigeria, …
INTRODUCTION The studied area lies between longitudes 5o22` to 5o40`E and latitude 7o42` to 7o55`N within the OhafiaOzuabam-Arochukwu areas of southeastern Nigeria (Fig. 1). Limestone is a sedimentary rock composed largely of the mineral calcite (CaCO3), which is formed either by organic or inorganic processes (Serra 2006).
In the same vein, limestone occurrences are reported in almost all the 36 States of the Federation with extensive deposits in Sokoto, Gombe, Benue, Kogi, Oyo, Ogun and Cross River States. Other Solid Minerals that can be found in Nigeria include; Tin, Gemstones, Kaolin, Tantalite, and Gypsum. 1.1 Nigeria Solid Mineral Industry
In Nigeria, for instance, some interests and advocacy groups had called for a referendum to endorse the constitution amendment process. This position has continuously been rejected by the National Assembly on the premise that the 1999 constitution does not provide for referendum. In Nigeria, the authority to amend the Constitution is derived
Nevertheless, the process is relatively simple: locate or create (minimal) breaks in the stone, remove the stone using heavy machinery, secure the stone on a vehicle for …

This document summarizes information on the geology and occurrences of limestone and marble deposits in Nigeria. It discusses the main sedimentary basins where limestone is found, including the Benue Trough, Sokoto, Dahomey and Chad Basins. Precambrian marble deposits are also described within the schist belt areas of western …
