CHEMICAL ANALYSIS OF MINERALS

SPECTROSCOPIC TECHNIQUES There are multi lltiple types of spectitroscopic thitechniques th tthat can be used to study the characteristics of elements that compose minerals. For the most part, all spectroscopic techniques take advantage of the same energy principals: 1) By bombarding a sample with energy, electrons and/or

The Science Behind Volcanoes

If a rhyolite lava flow cools quickly, it can quickly freeze into a black glassy substance called obsidian. When filled with bubbles of gas, and usually with explosive eruptions, the same lava will form pumice. If the same lave is allowed to cool slowly…it will form a light-colored, uniformly solid rock called rhyolite.

Lithogeochemical studies using immobile element patterns have shown that the Upper Amulet rhyolite is actually a hydrothermally altered andesite-dacite (Gibson and others, 1983; Barrett and MacLean, 1999). Similarly, in the intensely

Answer: A large igneous province (LIP) contains an immense volume of low-viscosity mafic lava that has erupted over a relatively short time and spread out in vast flows, some of which extend over 500 km from the vent.
