This study presented laboratory tests on the effects of several mineralizers added to black raw materials, in the manufacture of cement. This manufacturing process is based on crushing quarry limestones with clays and fuels in order to be fired at 1450°C to obtain clinker, the ma...
The relation between earthquake and planet motion is one of topics interesting to people. Based on conservation law of energy, this paper proves that the energy release by earthquake proportions to the square of velocity of Earth’s rotation, while velocities of revolution of Eart...
The identification of mineral in talcose rock requires definitive analytical methods due its similar structure in silicates and associated minerals. The used of microscopy and X-ray diffractometry have been found useful, practical for both exploratory and determinations of miner...
In this research, structures, geometries and directions of dominant stresses in the Abbar region (northwestern Iran) were examined. The fractures and lineaments of the area adequately matches to the brittle left-lateral shear zone model, and the two main fault systems of the area...
Igue Oke is located in the SW of Igarra Auchi sheet 266 SW, southwest basement complex of Nigeria. The rock types are made up of meta-sediments which includes marbles, migmatitic schists, meta-conglomerates, amphibolites, calc-silicate rocks which have undergone several deformati...
This study evaluated the quality of groundwater in the municipality of Abaetetuba (PA, Brazil 1°43'46'' S e 48°52'27'' W) based on the hydrogeological characterization and degree of vulnerability of the aquifer system. The municipality of Abaetetuba is practically all supplied by...
The state endowed with natural beauty, Uttarakhand, is analyzed in this study. The sustainable security of its social, ecological, economic aspects is measured using the sustainable livelihood security index framework. The state government is focusing on investments in hospitalit...
The samples of Awgu shale collected from Nnewi and Mgbowo in Awgu Local Government Area of Enugu state were analysed in the laboratory for such properties as linear shrinkage, moisture content and atterberg limits (plastic limit and liquid limit). The samples recorded moisture co...
The Ishiagu galena - sphalerite vein mineralization was investigated for its stable isotope composition to determine the characteristics and source of the mineralizing fluid. The δ34S of galena, sphalerite and chalcopyrite range from -5.00/00 to -8.00/00, -2.00/00 to -4.90/00 and...
Integrated geotechnical and geophysical investigations was carried out in order to harness the cause of the incessant subsidence of road pavement along section of Portharcourt - Eket road Southern Nigeria. The geotechnical investigation involves boring of boreholes and collection...
