Basalt is an igneous rock that is usually dark-colored and has a rough texture. It forms when magma rises to the Earth's surface and then cools quickly. Granite, on the other hand, is a lighter-colored rock than Basalt with a grained structure. It forms when molten magma stays underground or evaporates slowly over millions of years, …

Light colored and coarse Dark colored and fine Granite Basalt Well, for a start, why the great differences between two rocks like these? Especially when we realize no other planets have granite. Plus, we also want to know how two igneous rocks like granite and basalt could be related to each other – If they are.

Basalt is volcanic, or extrusive, forming at the surface, while granite is plutonic, or intrusive, forming beneath the surface. Basalt is mafic while granite is felsic. Basalt is common on both Earth and other Solar System bodies such as the Moon and Mars while granite is only common on Earth and rare elsewhere in the Solar System.

Final answer: Basalt is the igneous rock or magma with the least amount of light-colored silicates, as opposed to Granite, Andesite, and Rhyolite which are higher in light-colored silicates.The correct answer is option (A). Explanation: The igneous rock or magma with the least amount of light-colored silicates is Basalt. The key factor in …

Basalt, extrusive igneous (volcanic) rock that is low in silica content, dark in color, and comparatively rich in iron and magnesium. Basalts may be broadly classified on a chemical and petrographic basis into two main groups: the tholeiitic and the alkali basalts. Learn more about basalt in this article.

6.4 Metamorphic Environments. As with igneous processes, metamorphic rocks form at different zones of pressure (depth) and temperature as shown on the pressure-temperature (P-T) diagram. The term facies is an objective description of a rock. In metamorphic rocks facies are groups of minerals called mineral assemblages. The names of metamorphic …

The main difference between light granite and dark granite is the density of the stone. Light granite is not as dense as dark granite, making it slightly more vulnerable to stains, cracking, and other damage. All varieties of granite are incredibly durable, but darker stone tends to stand up better to excessive wear and tear.

Felsic igneous rocks, as a whole rock, tend to have light colors or shades: white, pink, light brown, light gray. Mafic igneous rocks, on the whole, tend to be dark colored, commonly black or dark gray. Most mafic magma originates by melting of rocks in the mantle that are extremely rich in iron and magnesium. Felsic magma usually originates in ...

For an igneous rock to be classified as rhyolite, it must be light colored, be fine grained, and contain. (1) quartz. (2) calcite. (3) pyroxene. (4) olivine. (1) quartz. The end product of the weathering of gabbro or basalt rocks is a solution of dissolved material that most likely would contain high amounts of. (1) iron and magnesium.

13+ Types of Black Rocks, Gems and Minerals. 1. Basalt. Basalt is a dark-colored, fine-grained, igneous rock mainly composed of plagioclase and pyroxene minerals. It forms as an extrusive rock, such as a lava flow, but can also be found in small intrusive bodies like an igneous dike or a thin sill.

For example, basic lavas (e.g., basalt) have a low viscosity and therefore flow easily, so that they form wide shield volcanoes. Magmas with a higher proportion of SiO 2 (acid lavas, e.g., rhyolite) are more ... Alkali feldspar granite—light-colored granite comprising mainly alkali feldspar (<10% plagioclase). Accessory minerals include ...
