Dissolved Iron From Basalt

Volcanoes, Magma, and Volcanic Eruptions

Since volcanic eruptions are caused by magma (a mixture of liquid rock, crystals, and dissolved gas) expelled onto the Earth's surface, we must first discuss the characteristics of magma and how magmas form in the Earth..

Basalt lava (amygdaloidal) - Department of Earth Sciences

Amygdaloidal basalt This is a basalt, a dark coloured volcanic rock formed from a magma of basic composition erupted on the Earth's surface. Magmas generally contain dissolved gas, which can form bubbles in the magma as the pressure is released on eruption.

Chemical Weathering | Processes of Change

Oct 04, 2010 · CHEMICAL WEATHERING. Like mechanical weathering, there are several different types of chemical weathering. One type is oxidation, the reaction of oxygen with iron-bearing minerals in rock. In an oxidation reaction, the iron atom loses electrons and precipitates as another mineral. Perhaps the most well-known oxidation reaction is the formation .
