摘要：The Azara Barites Mineralization in The Middle Benue Trough Occurs as Vein Infilling Materials associated with Lead-Zinc Lodes. A Fracture Formed as Single Linear Structures with thickness of generally not more than 0.5m. The Geological Characterization of The Azara Barite Deposits which Include; Geotechnical, Petrological And Geochemistry Were Studied Within The Four (4) Selected Veins Samples: V1 N (08020’40.6’’) E (0090 17’21.3’’) V 12 N(08021’59.0’’) E(009021’13.6’’) V13 N(08021’44.0’’) E (009021’14.6’’) V17 N(08022’27.1’’) E(0090 17’31.7’’). Soluble Alkaline Earth Metal Test (100mg/L) Indicate Presence of Calcium or Magnesium which is Good for Drilling Fluid, Hardness Capacity of the Veins Mineralization ranges From 3.0 to 3.5 with an average Specific Gravity of 4.2. this classify the Veins as a High Grade Barite. Fluid Performance was Measured based on Yield Point and Plastic Viscosity which is high even at aging and at high Temperature. Quantitative Mineralogical Analysis reveals Barite as the Main Mineral with an average of 92 Wt.% and Quartz as an associated Minerals with average of 8wt.%.The Mineralogy revealed a Mineralization with One of the purest Veins and less Number of Impurity, the Colour Index Criteria also classify the Veins to be Melanocratic (60-90).The Elemental Composition of the Veins show classes of Major Elements with average weight Percentage of greater than 1% (Sio2, SO3, Bao , Sro,) also reveal the Veins Are Oversaturated Based on The Composition of Sio2 And Metaluminous Group ( K2O+Na2O+Ca2>Al2O3>Na2O+K2O) With Modal Minerals Of Feldspar and Normative Minerals of Anorthite + Diopside. These have contributed to the grade and value of Azara Barite Mineralization Veins and its Purity and Quality for Exploration Purposes.
