Question

Difficulty: Very hardMineral and Energy Resources in Nigeria

Match each Nigerian mineral resource or energy generation plant on the left with its principal deposit location or host site on the right.

  • Barite (industrial vein deposits used in drilling mud)Azara, Nasarawa State
  • Lignite (Tertiary brown coal deposits)Ogwashi-Uku, Delta State
  • Jakura Marble (metamorphic crystalline carbonate)Lokoja axis, Kogi State
  • Egbin Thermal Power Station (gas-fired facility)Ikorodu axis, Lagos State

Answer

Barite matches with Azara (Nasarawa State); Lignite matches with Ogwashi-Uku (Delta State); Jakura Marble matches with Lokoja axis (Kogi State); and Egbin Thermal Power Station matches with Ikorodu axis (Lagos State).
Each resource or infrastructure item correctly pairs with its specific geographic site in Nigeria: Barite is mined at Azara (Nasarawa State); Lignite is concentrated at Ogwashi-Uku (Delta State); Jakura Marble occurs near Lokoja (Kogi State); and Egbin Thermal Power Station operates at Ikorodu (Lagos State).

Step-by-Step Solution

1
Identify the primary mining location for vein barite deposits in Nigeria.
Barite, vital as a weighting agent in petroleum drilling mud, is mainly mined from vein deposits located at Azara in Nasarawa State.
Hydrothermal mineralization in the Benue Trough concentrates industrial barite veins in Nasarawa State.
2
Locate the major Tertiary lignite (brown coal) seam formations in southern Nigeria.
Lignite deposits belong to the Ogwashi-Asaba geological formation, prominently exposed around Ogwashi-Uku in Delta State.
Unlike the Cretaceous sub-bituminous coal of Enugu, lignite is a younger Tertiary fuel found along the lower Niger sedimentary basin.
3
Determine the geographical location of the Jakura marble deposit.
Jakura marble occurs within the Precambrian Basement Complex rocks in Kogi State near Lokoja.
Metamorphic re-crystallization of ancient limestones created high-grade marble in the Lokoja district.
4
Identify the host location of the Egbin thermal power installation.
Egbin Thermal Power Station is situated along the lagoon at Egbin near Ikorodu, Lagos State.
It relies on natural gas piped from the Niger Delta oil fields to power steam turbines generating electricity for the national grid.
