Oct 23, 2017 · Andesite gets its name from the Andes mountains of South America, where arc volcanic rocks mix basaltic magma with granitic crustal rocks, yielding lavas with intermediate compositions. Andesite is less fluid than basalt and erupts with more violence because its dissolved gases cannot escape as easily.

How Does Chemical Weathering Work? - ThoughtCo

Mar 17, 2017 · Chemical weathering can dissolve rock or change its composition. In some cases, chemical weathering attacks and transforms the minerals in bedrock from primary minerals to surface minerals.. The two main processes in chemical weathering of igneous rocks are hydrolysis (which yields clays plus dissolved ions from plagioclase and alkali feldspar) and oxidation (which produces the iron .

Basalt | Revolvy

Basalt Basalt ()[1] is a mafic extrusive igneous rock formed from the rapid cooling of magnesium-rich and iron-rich lava[2] exposed at or very near the surface of a terrestrial planet or a moon. More than 90% of all volcanic rock on Earth is basalt.[3] Basalt lava has a low viscosity, due to its low silica content, resulting in rapid lava flows that can spread over great areas before cooling .

Natural Variations in the Composition of Groundwater

The amount and type of dissolved minerals in water is what gives waters their individual taste. Factors that control the dissolved minerals in groundwater include [1] the types of minerals that make up the aquifer, [2] the length of time that the water is in contact with the minerals, and [3] the chemical state of the groundwater.

Basalt is defined by its mineral content and texture, and physical descriptions without mineralogical context may be unreliable in some circumstances. Basalt is usually grey to black in colour, but rapidly weathers to brown or rust-red due to oxidation of its mafic (iron-rich) minerals into hematite and other iron oxides and hydroxides.

Iron ore develops in sedimentary rock containing two iron oxides: hematite and magnetite. These two compounds result from the oxygen emitted from plant life bonding with dissolved iron in the water, creating iron band formations on the ocean floor. Over millions of years, tectonic movement and plate shifts deposited the ore beneath the land.
