Petrological, whole-rock major and trace element, and Sr–Nd–Pb isotopic data are reported for the late Mesozoic Dzheltula alkaline igneous complex in the Aldan–Stanovoy Shield, Russia. The alkaline rocks are emplaced into the Tyrkanda mélange zone. The Dzheltula complex consists of monzonites, foid monzonites, and alkaline syenites; granite dykes intrude the complex. All alkaline rocks have high LILE contents (e.g., Ba and Sr), high light REE/HFSE ratios, strongly fractionated REE patterns, and typically lack Eu anomalies. Granite shows different major and trace-element characteristics in comparison to monzonites and syenites. The major and trace-element characteristics of the Dzheltula complex rocks and minerals are consistent with formation by combined assimilation and fractionation processes of an alkaline parental magma of lamproitic composition. The alkaline rocks have moderately radiogenic Sr (⁸⁷Sr/⁸⁶Sr(t) = 0.7057–0.7065) and unradiogenic Nd (ɛNd(t) = − 11.3 to − 15.2) and Pb (²⁰⁶Pb/²⁰⁴Pb = 17.17–17.26); granite has more enriched ⁸⁷Sr/⁸⁶Sr(t) value (0.707408) but similar ɛNd(t) = − 12.93 The trace element and Sr–Nd–Pb isotopic data for the Dzheltula complex indicate its mantle source experienced ancient metasomatic enrichment, probably associated with subduction.

据报道，俄罗斯阿尔丹-斯塔诺沃伊盾构的中生代Dzheltula碱性火成岩晚期具有岩石学，全岩石主要和微量元素以及Sr-Nd-Pb同位素数据。碱性岩石被放到Tyrkanda混杂区中。Dzheltula复合物由单长石，无定形单长石和碱性正长岩组成。花岗岩堤防侵入了该建筑群。所有碱性岩石都具有较高的LILE含量（例如Ba和Sr），较高的轻REE / HFSE比，强烈分馏的REE模式，并且通常缺乏Eu异常。与单长石和正长岩相比，花岗岩显示出不同的主要和微量元素特征。Dzheltula复杂岩石和矿物的主要和微量元素特征与成岩成分的碱性母岩浆的合并同化和分馏过程形成一致。碱性岩石具有适度的放射源Sr（⁸⁷ SR / ⁸⁶ Sr（上吨）= 0.7057-0.7065）和unradiogenic钕（ɛ钕（吨）= - 11.3至- 15.2）和Pb（²⁰⁶ PB / ²⁰⁴ PB = 17.17-17.26）; 花岗岩已更富集⁸⁷ SR / ⁸⁶ Sr（上吨）值（0.707408），但类似ɛ钕（吨）= - 12.93为Dzheltula痕量元素和锶的Nd-Pb同位素数据复杂表明其地幔源经历古交代富集，可能与俯冲有关。
