This paper presents the first geochemical data on detrital tourmaline and rutile from sedimentary rocks of the upper Devonian Ilanqareh Formation (Fm.) which is extended in the Azarbaijan area in NW Iran. The deposits have typically mature character with ultra-stable heavy minerals predominantly derived from the metamorphic rocks. The detrital tourmaline has mainly dravitic, uvitic and Mg-foititic composition, thus indicating metaultramafic source rocks and common metapelites and metapsammites. Detrital rutile geochemistry indicates the presence of lower-up-to-upper amphibolite facies metapelitic source rocks, and part of this rutile most likely underwent granulite facies metamorphism. Unique detrital V-bearing tourmaline with high V₂O₃ content up to 8.93 wt% indicates its primary derivation from far-distant source rocks in the East African Belt and adjacent areas. This is confirmed by both the exceptional geochemistry and the shape and roundness of the tourmaline which indicate recycled detrital origin and multiple reworking. The less frequent V-bearing rutile also indicates the same sources. These results confirm the wide circulation of sediments distributed by the Gondwana super-fan system from the inner parts of this super-continent to the Gondwana and peri-Gondwanan terrain continental margins, and also their later re-distribution during the Devonian era. The results highlight the significant contribution from Gondwanan sources to the supply of upper Devonian siliciclastic formations in NW Iran compared to those from the Iranian plate.

本文提供了关于伊朗西北阿扎拜疆地区延伸的上泥盆统 Ilanqareh 组 (Fm.) 沉积岩中碎屑电气石和金红石的第一次地球化学数据。矿床具有典型的成熟特征，主要来自变质岩的超稳定重矿物。碎屑电气石主要为闪长岩、葡萄岩和镁橄榄岩成分，表明为变质岩性烃源岩和常见的变质岩和变质岩。碎屑金红石地球化学表明存在自下而上的角闪岩相变泥质烃源岩，并且该金红石的一部分很可能经历了麻粒岩相变质作用。具有高 V ₂ O _{3 的}独特碎屑 V 轴承电气石含量高达 8.93 wt% 表明其主要来源于东非带及邻近地区的远距离烃源岩。电气石的特殊地球化学特性以及形状和圆度都证实了这一点，这表明可回收碎屑来源和多次再加工。频率较低的 V 型金红石也表明来源相同。这些结果证实了冈瓦纳超级扇系统分布的沉积物从该超级大陆内部到冈瓦纳和冈瓦纳大陆边缘的广泛环流，以及它们在泥盆纪后期的重新分布。结果表明，与伊朗板块相比，冈瓦纳盆地源对伊朗西北部上泥盆纪硅质碎屑岩地层的供应有显着贡献。
