| Abstract: | The Archean granite rocks in Daba-jianshe area are consisted of tonalite, trondhjemite,granudiorite,which belong to TTG-system.Their characteristics on geology,petrology andgeochemistry show that they originated from plutonic intrusive rock bodies which the magmastemed from partly molten crust materials,and then underwent through the tnetamorphism ofgreenschist facies with the isotopic age being 2 443Ma. |
