SHRIMP wspiera szczegółową kartografię geologiczną w Sudetach

For the first time, at the beginning of the 2nd edition of the Detailed Geological Map of the Sudetes 1 : 25,000, new, extended geochronological studies using the U-Pb method on zircons by means of the modern SHRIMP device were planned. They were completed by chemical dating of monazites with the WDS Cameca Sx100 electron microprobe. As a result of age studies about 920 new U-Pb zircon analyses were obtained from 28 samples of the several important rock-types of the Góry Sowie Metamorphic Complex, which significantly expands the scope of radiometric age record in this area. Apart from age, other diagnostic parameters were also used, such as Th/U ratios in zircon. They allow better understanding of the extremely complicated tectonometamorphic evolution of the Góry Sowie Metamorphic Complex during the complex orogenic processes in the Paleozoic in the NE part of the Bohemian Massif.
