    Basalts are important rocks within metamorphic belts, as they can provide vital information on the conditions of metamorphism within the belt. Metamorphosed basalts are important hosts for a variety of hydrothermal ore deposits, including gold deposits, copper deposits, volcanogenic massive sulfide ore deposits and others. Compared to other rocks found on Earth's surface, basalts weather relatively fast. The typically iron-ric

    Basalt: Igneous Rock - Pictures, Definition, Uses More

    GeologyOverviewFormationLocationsExamplesUsesBasalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill. It has a composition similar to gabbro. The difference between basalt and gabbro is that basalt is a fine-grained rock while gabbro is a coarse-grained rock. Basalt underlies more of Earth's surface than any other rock type.

Heavy particles, such as gold, are likely to accumulate against the harder rock while the lighter materials are more easily moved away.

    Basalt Basalt is a mafic extrusive rock, is the most widespread of all igneous rocks, and comprises more than 90% of all volcanic rocks. Because of its relatively low silica content, basalt lava has a comparatively low viscosity, and forms thin flows that can travel long distances. It is also found as intrusive dikes and sills.

    The Density of Common Rocks and Minerals - ThoughtCo

    Rock density is very sensitive to the minerals that compose a particular rock type. Sedimentary rocks (and granite), which are rich in quartz and feldspar, tend to be less dense than volcanic rocks. And if you know your igneous petrology, you will see that the more mafic (rich in magnesium and iron) a rock is, the greater its density.
