However, the temperatures and oxygen fugacity of magmas at high level magma chamber decreased along with fractional crystallization.
但在高位岩浆房中,随着分离结晶作用的进行,岩浆的温度和氧逸度逐渐降低。
They are formed from alkali basaltic magma that slightly melted out of continental mantle by AFC mixing in depth, especially by the fractional crystallization in shallow horizon.
它是大陆地幔低度部分熔融产生的碱性玄武岩浆,通过深部AFC混合,尤其是浅部结晶分异机制形成的。
Beside fractional crystallization model, liquid immiscibility of Fluorine-rich granite magma is an important mechanism to form pegmatite and pegmatite type deposit.
除了结晶分异模式外,富氟花岗岩浆液态不混溶作用也是伟晶岩成岩成矿的重要机制。
