The first zircon U-Pb dating (SHRIMP II) for the silurian ophiolites in the Urals

Doklady Earth Sciences, 2010
The rocks of the ophiolite association are wide spread within the Ural mobile belt. For this reason dating of their formation is of great interest due to its tectonic significance, allowing interpretation of the history of geological development of the region.

U-Pb SHRIMP dating of zircons from metamorphic complexes in eastern Kamchatka

Russian Journal of Pacific Geology, 2012
The metamorphic complexes of eastern Kamchatka exposed on the Khavyven Highland and Karaginsky Island, as well as on the Kamchatka and Ozernoi peninsulas, compose large (up to 1.5 km) elongated blocks spatially associated with ophiolitic peridotite and gabbroic rock bodies (the Khavyven Highland and Karaginsky Island) or make up isolated fragments and ...

Qingbaikouan and Crygenian in South China: Constraints by SHRIMP Zircon U‐Pb dating

Acta Geologica Sinica - English Edition, 2013
AbstractThe Qingbaikouan System is the lowest unit of the Neoproterozoic Erathem in Chinese stratigraphic succession, and it now provides a precise geochronological framework and geological time scale for mapping and stratal correlation in China. However, a sensitive high‐resolution ion microprobe (SHRIMP) U‐Pb zircon age date (1368±12 Ma) obtained ...

Conventional and SHRIMP U-Pb Zircon Dating of the Chor Granitoid, Himachal Himalaya

Journal of the Geological Society of India, 2003
Abstract Conventional zircon U-Pb analyses of optically clear multi-grain fractions from the Chor Granitoid sample - CH 174 provide a complex pattern with eight points yielding a reference line with an upper intercept age of c. 910 Ma and large scatter. Three zircon fractions from the more deformed sample CH 4/11 of this body define a
