Abstract :

Hornfels outcrops as one of the rock units in Dehnow area, contains tourmaline as an accessory mineral. Based on the, microprobe analysis, tourmaline is alkali in composition and schorl-dravite type. Considering the chemical composition of tourmaline and its association with hornfels, it seems that Na, Ca, Fe, Al, and Mg originated from the politic sediments and formed tourmaline at the P-T conditions prevailing during contact metamorphism. On the other hand, other components such as B seem to have originated from the tonalite body.
