The andesites and dacites may have formed from basaltic magma by asthenospheric mantle, lithospheric components may have contributed however.
12.
During volcanic activity a fibrous material may be drawn by vigorous wind from molten basaltic magma called Pele's hair.
13.
Nakhlites are igneous rocks that are rich in augite and were formed from basaltic magma about 1.3 billion years ago.
14.
Many researchers have argued that anorthosites are the products of basaltic magma, and that mechanical removal of mafic minerals has occurred.
15.
As the oceanic Yangtze Craton subducted under the continental North China Craton, magmatic activities result in the formation of hydrated mafic basaltic magma.
16.
Possibly, the magma chamber of stage I had almost solidified when the injection of basaltic magma at depths of over triggered a remelting.
17.
The key factors in generating a Hawaiian eruption are basaltic magma and a low percentage of dissolved water ( less than one percent ).
18.
A typical theory is as follows : partial melting of the mantle generates a basaltic magma, which does not immediately ascend into the crust.
19.
Where hotspots occur under continental crust, basaltic magma is trapped in the less dense continental crust, which is heated and melts to form rhyolites.
20.
Volcanic activity was most likely triggered by the injection of basaltic magma into the felsic magma chamber days or weeks before the actual eruption.
