Abstract :

Hornblende-biotite tonalites are the most aged igneous rocks of the area that intruded into the metamorphic rocks and flisch. Based on microprobe analyses of biotite show they are annite-siderophyllite in composition. According to the composition of biotite they have a magmatic series were peraluminous to calcalkaline. Temperatures gained by application of Ti in biotite thermometry method are 500 to near 700 °C in 4 to 6 kbars.
