The paper discusses the results of U-Pb isotope dating monazites and zircons from granitoids formed under PT conditions granulite amphibolite facies gneisses, crystalline shales that are like xenoliths in these Ukrainian Shield. In some cases, such as Berdychiv-type Zhezhelivsky quarry, age values outer edges coincide well; others, granites Ivanivsky they differ by more than error. Odessa even ...

The area of Esfordi-Zarigan in Central Iran is located in Bafq metallogenic province where most the rock units belong to Precambrian, Infracambrian and Cambrian periods. Although the sedimentary and volcanic rocks are widely distributed, this research is mainly focused on petrogenesis of plutonic rocks. From stratigraphic point of view sedimentary and volcanic rocks can be classified in five ma...

The Eshamy suite plutons (ESP) are in the midst of the Sanak-Baranof (SB) belt, a series of neartrench, Paleocene to Eocene granitic intrusions into the Chugach-Prince William (CPW) terrane flysch along the southern margin of Alaska (Fig.1, Garver and Davidson, this volume and references therein). Intruded from 62-48 Ma, west-to-east migration of a subducting north-south-striking mid-ocean ridg...
