Ore can also accumulate when seawater circulates through cracks in the Earths crust and deposits minerals in the areas around hydrothermal vents. This is called a hydrothermal process. Finally, ore can accumulate through processes that take place on the surface of the Earth, such as erosion. This type of ore genesis is called a surficial process.
