Title

ORIGIN OF TOURMALINE IN DEHNO INTRUSIVE - NORTH EAST OF ALIGUDARZ

Pages

  55-68

Abstract

 The pervasive METASOMATISM in the margin of the Delmo intrusive body has generated different variety of tommalinization in the host pelitic rock; 1) Stratiform tourmalinites in pelitic hornfelses; 2) Pegmatitic vein in arenitic sediments; and 3) Qumiz-TOURMALINEthin veins that cover the surface of pegmatitic veins. The Fe/(Fe+Mg) ratio for TOURMALINE in stratiform tourmalinites, pegmatites and veins are in the range of 0.484-0.553, 0.375-0.509 and 0.357-0.509, respectively. These TOURMALINEs are schorl-dravite solid solution. The chemical zonation in these minerals reflects the fluctuating conditions expected from fluid mixing in open systems. The fractionated REE patterns in stratiform TOURMALINEs in spider diagram show sedimentary origin of these minerals. This pattern in pegmatite and vein tommalines is flatted indicating the mobility of LREE as a result of alteration of host arenitic sediments that caused the increased HREE/LREE in these two types of TOURMALINEs.
