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, 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. Most areas within Earth's ocean basins are underlain by basalt.asalt is used for a wide variety of purposes. It is most commonly crushed for use as an aggregate in construction projects. Crushed basalt is used for road base, concrete aggregate, asphalt pavement aggregate, railroad ballast, filter stone in drain fields and may other purposes.
In other words, the alcohol by volume (ABV) is 14%. Distilled spirits are labeled differently. If you look on a bottle of distilled spirits, you will see another number and word â also in very tiny letters â that will read â80- proof.â Proof is a number equal to twice the ABV.
Most cognac, or hard liquor in general, is not above 80 proof, which is 40% alcohol. What determines whether a drink will bu â¦ rn is what it is made of, not what it's called. Cognac could burn if it has a high enough alcohol percentage. Most 80 proof liquors do not burn, but most 100 proof do, meaning somewhere in there, around 90 proof, is the point where it could be flammable. A good example is bourbon or gin, some are only 40% alcohol, but Maker's Mark and Bombay Sapphire are both around 45 to 47%...they tend to burn. 2 people found this useful.
