Resistivity: This is a fundamental physical property of metal in a wire. Though related to resistance, it is not the same. Resistance (R) depends on length, area, and the material’s properties, which are collectively described by this term.R = ρL/A, where:R =...

The diversified geology of various regions and stratigraphic levels within the sedimentary basin have given rise to a wide variety of minerals, more than 50 different kinds other than oil, gas, and coal, that have an existing or potential resource value. Organic...

The rate of chemical weathering isn’t the same everywhere—it depends on factors like climate, rock type, water flow, and biological activity. Warmer, wetter conditions speed up reactions, while fractures in rocks allow water to seep in and break them down over time....

Chemical weathering involves the chemical breakdown of bedrock and the formation of new mineral products. A detailed treatment of the processes in chemical weathering is found in Anderson and Anderson (2010, p. 183–202), and a very brief overview is provided here. The...

Sedimentary basins are morphotectonic depressions on Earth’s crust, which accumulate a considerable amount of sediments over geological time. Sedimentary basins are the repositories of a great volume of economic deposits, including hydrocarbons, coals, groundwater,...

Types of traps are geological structures that retain hydrocarbons, preventing further movement. They include structural, diapiric, stratigraphic, hydrodynamic, and combination traps formed by rock deformation, sediment movement, or water flow. Understanding these...
