Geology of Madeira to the end of the Pleistocene ice ages means that some Quaternary marine terraces are as much as 100 meters above sea level. Groundwater on Madeira is held in fractured volcanic rock aquifers, with widely varying transmissivity and dissolved mineral content. Water is generally slightly acidic to slightly alkaline and cold, although there are small quantities of thermal water near fault zones. Much of the water on the island comes from high-discharge springs. Leptosols, cambisols and andisols are the three main soil types on the island. Madeira has few natural resources and no mining, aside from small-scale extraction of sand
