magmas

The metallogenic material was from deep alkalic basaltic magma, and the pulsatory invasion was the necessary metallogenic condition of the ore deposit.

The magma of porphyritic moyite-monzogranite series in the middle stage mainly originated from the lower crust, being the product of collision-orogeny.

Beside fractional crystallization model,liquid immiscibility of Fluorine-rich granite magma is an important mechanism to form pegmatite and pegmatite type deposit.

Hence, for the minerals to be analyzed in some rocks, when there are all sorts of genesis with xenolith, magma, mantle and so on in them,the age of a certain single event can be respectively got.

The types of deposits basically are differential metasomatism in the later magma, pneumatolytic hydrothermal process, pegmatite process, residual deposits and placer deposits.

The volcano erupted, spewing hot magma everywhere.

Geologists study the composition and behavior of magma.

Magma can solidify to form igneous rocks like granite.

The magma chamber beneath the volcano is expanding.

Magma can reach temperatures of over 1,000 degrees Celsius.

The cooling of magma leads to the formation of crystals.

Magma is a mixture of molten rock, gases, and solids.

Magma rising to the surface can trigger volcanic eruptions.

The movement of magma beneath the Earth's crust causes earthquakes.

Minerals dissolved in magma can crystallize as it cools.
