1·The earlier units contain abundant mafic micro-enclaves, and the petrographic study of the enclaves indicates the crust-mantle mixing origin of the granitic magma.
较早次单元中富含镁铁质微粒包体，经包体岩相学研究，花岗岩浆具壳幔混合成因。
2·The example to process the Sichuan series of red granites indicates that the sawability will be effected by the petrographic characters of the granites.
并以四川红系列花岗岩石材加工为例，说明了花岗岩岩相学特征对岩石可锯性影响的程度。
