PETROCHEMICAL AND GEOCHEMICAL CHARACTERISTICS OF THE LINGLONG GRANITES

摘要:

Abstract:

The petrological,mineralogical,petrochemical and geochmical character- istics of the Linglong granites are similar to those of granitization granites. The variation from the gneissic granite to the medium-coarse grained gra- nite reflects the different ways with which the rocks were formed,and also the course of granitization from the gneissic granite to the medium-coarse grained granite. The Linglong granites,especially the gneissic granite have higher Na and Au contents and lower W、Sn、Mo、Be、Nb and Ta cont...
