Basalt commonly features a very fine-grained or glassy matrix interspersed with visible mineral grains. The average density is 3.0 gm/cm3. Basalt is defined by its mineral content and texture, and physical descriptions …What is Basalt? Basalt 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, …

Two basalt samples, chosen to provide a range of source rock compositions and textures, were crushed and sieved. We quantify variations in sediment mineral proportions as a function of grain size, as well as accompanying changes in major- …Gabbro and Basalt are Related. Gabbros are equivalent in composition to basalts. The difference between the two rock types is their grain size. Basalts are extrusive igneous rocks that cool quickly and have fine-grained crystals. …

The montmorillonite and kaolinite formed by the weathering of Emeishan basalt, together with the fine particles created by the fragmentation of Emeishan basalt saprolite, might have pervaded the spaces among the coarse debris and trapped the compressed air, which may have supported the debris in the rapid rock avalanche flow. ... The grain size ...In the United States and Canada, the name " diabase " is used for a dark gray to black, fine-grained, intrusive igneous rock that has a composition similar to basalt and gabbro. The difference between basalt, diabase, and gabbro is in their grain size - which was determined by their cooling rates. Basalt: rapid cooling in a lava flow produced ...
