Basalt - an overview | ScienceDirect Topics

Basalt is an easily datable rock and thus is a handy tool when available. Basalt flows emanating from the Uinkaret field between the Hurricane and Toroweep faults spilled into the Grand Canyon as shown in Figure 14.19. These basalts have been used to determine Colorado River incision rates.

The Density of Common Rocks and Minerals - ThoughtCo

Jan 15, 2019 · Rock Densities. 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 ...

Basalt and Granite

Basalt is commonly very fine grained, and it is nearly impossible to see individual minerals without magnification. Basalt is considered a mafic silicate rock. Among other characteristics, mafic minerals and rocks are generally dark in color and high in specific gravity. This is in large part due to the amount of iron, magnesium, and several ...
