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, such as an igneous dike or a thin sill.It has a composition similar to gabbro.The difference between basalt and gabbro is that …

Famous quotes containing the word distribution: " In this distribution of functions, the scholar is the delegated intellect. In the right state, he is, Man Thinking. In the degenerate state, when the victim of society, he tends to become a mere thinker, or, still worse, the parrot of other men's thinking.

For basalt, the Th/U ratio ranges from 3.8 to 7.3, and the K/U ratio from 0.7 × 10 −4 to 2.3 × 10 −4. The values of ratios for red bole also fall within the above range. Variations of these ratios for consecutive sub-layers within each layer have also been analyzed. Data indicate uneven radioelemental distribution between the layers.
