The study of Microprobe Analyses in different tourmaline bearing unites in Boroujerd area, for example, quartz tourmaline veins in Nezamabad quartz diorites, Aplite-pegmatite tourmaline bearing Ghalesamorkhan, Gijali and Kabotarlan granodiorites, pegmatite veins in Kolahjob schist and nodular tourmaline in Dehgah and Astaneh show that most tourmalines in Boroujerd area are schorlite. Needle like Ghalae Samorkhan and some samples from Kolahjob - Gijali are foitite. Euhedral and none zoning, high Fe/Fe+Mg, low X site vacancy and high Al amount  in more of tourmaline are reasons of magmatic source. The occurrence of tourmaline in peraluminous granite Dehgah and Astaneh is evidence of enriched B magma source. Therefor, the studied area tourmalines depend of granitic source and originate of hydrothermal fluid to magmatic source.
