How are resources related to geologic structures?

What will be an ideal response?


Answer: "Gas is less dense than oil, and oil is less dense than water. As a result of this density contrast, oil and natural gas migrate upward through pores toward Earth's surface unless impeded by low-porosity layers, which trap the oil and gas. Anticlines and faults form common traps for oil and natural gas. The oil and gas migrate upward to the highest point below a nonporous layer along the hinge line of an anticline and are trapped beneath reverse and thrust faults where low-porosity layers are displaced on top of high-porosity layers. Metal-rich mineral resources commonly form along joints and faults where warm fluids with high concentrations of metal ions readily flow and cool to precipitate metallic minerals."
