The study reports and discusses new LA–ICP–MS zircon U–Pb data and major and trace element analyses for 16 samples from nine different plutons intruding the Getic (Brnjica, Neresnica, Ziman, Gornjane–Tanda–Blizna), and the Danubian (Aldinac, Janja, Ravno Bučje, Plavna and Suvodol) units of the East Serbian Carpatho-Balkanides (ESCB). Within the entire ESCB belt predominate slightly peraluminous granitoids, ranging in composition from biotite–hornblende tonalite through granodiorite to monzogranite. They contain mafic enclaves and are often cut by lamprophyre shallow intrusions and show gradual transitions to, or are cut by muscovite-bearing granitoids. All the above mentioned rocks formed under post-collisional conditions with some of them displaying evidence of post-emplacement shearing and recrystallization. By contrast, the garnet-bearing muscovite granite of Ziman (Getic unit) is distinctively peraluminous and shows evidence of syn-collisional emplacement and crystallization. The most reliable U–Pb zircon ages on the post-collisional granitoids show an age range between ~ 323 and ~ 290 Ma. The granitoids of the Getic unit reveal better concordia ages suggesting that Variscan magmatism lasted longer than previously thought, i.e., even until Permian times. On the other hand, the concordia age of 325.8 ± 1.2 Ma for the syn-collisional Ziman granitoid likely represents a minimum age for the collision event in this part of the Variscan belt. The ages of the Danubian plutons at least allow for discussing still open questions, such as (1) whether the Danubian intrusives are systematically older than those intruding the Getic basement, (2) if Variscan syn-collisional plutons do exist in the Danubian unit, and (3) what role the Variscan magmatism played in the formation of uranium mineralization in the area.

东塞尔维亚喀尔巴鄂-巴尔卡尼德斯的瓦里斯卡花岗岩：从U–Pb锆石年龄和地球化学数据推断出的新见解

该研究报告并讨论了LA-ICP-MS锆石U-Pb的新数据以及16种样品的主要和微量元素分析，这些样品来自侵入盖蒂奇（Brnjica，Neresnica，Ziman，Gornjane-Tanda-Blizna）和Danubian（东塞尔维亚喀尔巴多-巴尔卡尼德斯（ESCB）的Aldinac，Janja，RavnoBučje，Plavna和Suvodol部队。在整个ESCB带中，主要为轻质的高铝质花岗岩，其成分从黑云母–角闪石斜长石到花岗闪长石再到辉长花岗岩。它们包含镁铁质飞地，通常被煌斑岩浅层侵入物切割，并逐渐向含白云母的花岗岩过渡，或被含白云母的花岗岩切割。上面提到的所有岩石都是在碰撞后的条件下形成的，其中一些显示出位移后剪切和重结晶的迹象。相比之下，Ziman（Getic单元）的含石榴石白云母花岗岩具有明显的高铝质，并显示出同碰撞碰撞和结晶的证据。碰撞后花岗岩上最可靠的U–Pb锆石年龄显示在〜323和〜290 Ma之间。Getic单元的花岗岩显示出更好的共生年龄，表明Variscan岩浆作用的持续时间比以前认为的要长，即直到二叠纪。另一方面，同碰撞Ziman花岗岩的共生年龄为325.8±1.2 Ma，可能代表了Variscan带这部分碰撞事件的最小年龄。达努比小行星的年龄至少可以用来讨论仍然悬而未决的问题，例如（1）达努比侵入体是否在系统上要比侵入盖蒂奇地下室的系统老，
