Zircon xenocrysts in Late Cretaceous magmatic rocks in the Kermanshah Ophiolite: link to Iran continental crust supports the subduction initiation model

Soviet Economy, 2022
Geochronological and geochemical data show that Late Cretaceous Zagros ophiolites were generated by forearc seafloor spreading during a subduction initiation event along the southwestern margin of Iran.

Desilicification Rims of Zircon Xenocrysts Record the Timing of Kimberlite Emplacement

Journal of Geophysical Research: Solid Earth, 2022
AbstractKimberlites are deep and relatively rare mantle‐derived igneous rocks, which provide key insights into the lithospheric mantle composition beneath continents (i.e., from the entrained mantle materials) at the time of magma emplacement. In addition, the temporal distribution of kimberlites throughout Earth's history may reveal secular changes in

Paleoproterozoic basement beneath the Eastern Cathaysia Block revealed by zircon xenocrysts from late Mesozoic volcanics

Precambrian Research, 2020
The Eastern Cathaysia Block located to the western side of the Pacific Plate was mainly covered by late Mesozoic intrusive and volcanic rocks, and the age and composition of its basement remain enigmatic.

Unexposed Archean components and complex evolution beneath the Cathaysia Block: Evidence from zircon xenocrysts in the Cenozoic basalts in Leizhou Peninsula, South China

Journal of Asian Earth Sciences, 2020
Magmatic systems exposed at the surface can sample the deep crust during the ascent of magmas from deep lithosphere. Zircons captured by such rocks, especially those with pre-eruption ages (xenocrysts), can be used to extract information on the formation
