Permian biotite leucogranites to granite porphyries and rhyolites form small intrusions in several Alpine tectonic units in the Western Carpathians and the Pannonian region (Slovakia and Hungary). Their A-type signature is inferred from main- and trace-element geochemistry, with high K, Rb, Y, REE, Zr, Th, Nb, Fe/Mg and Ga/Al, low Al, Mg, Ca, P, Sr, V and strong negative Eu-anomaly. This geochemical signature is further supported by the mineralogy comprising local hypersolvus alkali feldspars, annitic biotite and the presence and composition of HFSE accessory minerals. The δ¹⁸O values measured for zircon (mean value 8.3 ‰ ± 0.36) may be explained by the melting of igneous material of crustal origin and/or mantle basalts which interacted with low-temperature fluids. The in-situ SHRIMP U–Pb isotope dating of zircon from the granites highlights two different periods of magmatic crystallisation and pluton emplacement: the older 281 ± 3 Ma Cisuralian age in the southern part, Velence Hills in the Pannonian region (Transdanubian Unit) and younger Guadalupian ages in the northern part, the West-Carpathian area: 262 ± 4 Ma (Turčok, Gemeric Unit), 267 ± 2 Ma (Hrončok, Veporic Unit) and 264 ± 3 Ma (Upohlav, granitic pebbles in Cretaceous conglomerates of the Pieniny Klippen Belt). The ~ 280 to 260-Ma interval is simultaneous with post-orogenic or anorogenic, rift-related and mainly alkaline (A-type) magmatism on the broader European scale. Our study documents a close relationship between the Permian continental rifting and the Neotethyan Meliatic oceanic basin opening in the Middle Triassic. The A-type granites originated from the partial melting of the ancient lower crustal quartzo-feldspatic rocks with the possible contribution of meta-basic material from the mantle in an extensional tectonic regime consistent with disintegration of the Pangea supercontinent during the Permian–Triassic period.

二叠纪黑云母白花岗岩到花岗岩斑岩和流纹岩在西喀尔巴阡山脉和潘诺尼亚地区（斯洛伐克和匈牙利）的几个高山构造单元中形成小的侵入体。它们的 A 型特征是从主要和微量元素地球化学推断出来的，具有高 K、Rb、Y、REE、Zr、Th、Nb、Fe/Mg 和 Ga/Al，低 Al、Mg、Ca、P、Sr , V 和强负 Eu 异常。这种地球化学特征得到了矿物学的进一步支持，该矿物学包括当地的超溶解碱长石、镍长石黑云母以及 HFSE 副矿物的存在和组成。δ ¹⁸锆石的 O 值（平均值 8.3 ‰ ± 0.36）可以用地壳起源的火成岩材料和/或与低温流体相互作用的地幔玄武岩的熔化来解释。花岗岩锆石的原位 SHRIMP U-Pb 同位素测年突出了两个不同时期的岩浆结晶和岩体侵位：南部较早的 281 ± 3 Ma Cisuralian 年龄，Pannonian 地区的 Velence Hills（Transdanubian Unit）和北部、西喀尔巴阡地区较年轻的瓜达卢普阶年龄：262 ± 4 Ma（Turčok，Gemeric Unit），267 ± 2 Ma（Hrončok，Veporic Unit）和 264 ± 3 Ma（Upohlav，白垩纪砾岩中的花岗岩鹅卵石） Pieniny Klippen 腰带）。~ 280 至 260 Ma 间隔与造山后或无造山同时，在更广泛的欧洲范围内与裂谷相关的主要是碱性（A 型）岩浆作用。我们的研究记录了二叠纪大陆裂谷与中三叠世新特提斯美利阿海盆地开口之间的密切关系。A型花岗岩起源于古老的下地壳石英-长石岩的部分熔融，可能是地幔中变基性物质在伸展构造体系中的贡献，与二叠纪-三叠纪期间盘古超大陆的解体一致。
