The Most Silica Enriched Types of Olgatos

The most silica enriched type of olgatos, typically in terms of the material that produces them, are called lava domes. And these are typically circular mounds which form as result of slow extrusion of very viscous lava. They can also form by by d gasing of of fluid magma, which we won't talk too much about. But they're not exclusively formed by high silica lava, but that is one way that they can be formed. There are also other land forms that can be caused by the products of volcanic activity and so now wewill turn to talking about some of these.
