Where and how does intermediate magma form?

Intermediate or Andesitic magma typically erupts at temperatures of 800–1000*C. The process of formation of intermediate magma is not as such different from that of basaltic or rhyolitic magma. read more

The process of formation of intermediate magma is not as such different from that of basaltic or rhyolitic magma. In order to generate a magma in the solid part of the earth either the geothermal gradient must be raised in some way or the melting temperature of the rocks must be lowered in some way. read more

Intermediate magma has higher silica content (roughly 60%) than mafic magma. This results in a higher gas content and viscosity. Its mean temperature ranges from 800 o to 1000 o Celsius (1472 o to 1832 o Fahrenheit). read more
