The chemical variation of the volcanics are controlled by both residual of plagioclase in the melting source area and crystalfractionation of biotite after magma formation.
认为火山岩的成分分异受斜长石在岩浆源区熔融残留和岩浆形成后黑云母的结晶分离双重控制。

Petrologic, geochemical and isotopic studies prove that the Badashi dioritic enclaves are autoliths and the earlier products generated by crystalfractionation of the host granite parental magma.
Parameters effecting on dry fractionation of lard are crystallization temperature, cooling rate, crystal growing time, agitation rate, separating manner.
