Abstract

Abstract Detailed cathodoluminescence (CL) and back scattered electron (BSE) imaging of zircon crystals, coupled with in-situ U-Pb zircon dating by Laser Ablation Multi-Collector Inductively Coupled Plasma Mass Spectrometry (LA-MC-ICP-MS) were used to develop new insights into the evolution of a monzogranite from Omanovac Quarry (Psunj Mt.), and of monzogranites from Šandrovac Quarry and Kišeljevac Creek (Papuk Mt.), both located in the Slavonian Mountains (Croatia). U-Pb isotopic data yielded a concordia age of 380 ± 4 Ma for the monzogranite from Omanovac Quarry, and 382 ± 2 Ma and 383 ± 5 Ma for monzogranites from Šandrovac Quarry and Kišeljevac Creek. The results suggest Late Devonian magmatic activity.

克罗地亚Psunj和Papuk Mts花岗岩的地质年代

摘要锆石晶体的详细阴极发光（CL）和背散射电子（BSE）成像，结合激光烧蚀多收集器电感耦合等离子体质谱（LA-MC-ICP-MS）原位U-Pb锆石定年，对Omanovac采石场（Psunj Mt.）二长花岗岩的演化进行了新的见解，来自Šandrovac采石场和Kišeljevac Creek（Papuk Mt.）的二长花岗岩，均位于斯拉沃尼亚山脉（克罗地亚）。U-Pb同位素数据显示，来自Omanovac采石场的二长花岗岩的伴生年龄为380±4 Ma，来自Šandrovac采石场和Kišeljevac Creek的二长岩体的伴生年龄分别为382±2 Ma和383±5 Ma。结果表明晚泥盆纪有岩浆活动。

期刊介绍： Geochronometria is aimed at integrating scientists developing different methods of absolute chronology and using them in different fields of earth and other natural sciences and archaeology. The methods in use are e.g. radiocarbon, stable isotopes, isotopes of natural decay series, optically stimulated luminescence, thermoluminescence, EPR/ESR, dendrochronology, varve chronology. The journal publishes papers that are devoted to developing the dating methods as well as studies concentrating on their applications in geology, palaeoclimatology, palaeobiology, palaeohydrology, geocgraphy and archaeology etc.
