Lower crustal zircons reveal Neogene metamorphism beneaththe Pannonian Basin (Hungary)
Open Geosciences, 2015 Neogene alkaline intraplate volcanic depositsin the Pannonian Basin (Hungary) contain many lowercrustal granulite-facies xenoliths. U-Pb ages have been determinedfor zircons separated from a metasedimentaryxenolith, using LA-ICPMS and SHRIMP techniques ...

Exploring the Moon's surface for remnants of the lunar mantle 1. Dunite xenoliths in mare basalts. A crustal or mantle origin? [PDF]
, 2015 Remotely sensed observations from recent missions (e.g., GRAIL, Kaguya, Chandrayaan-1) have been interpreted as indicating that the deep crust and upper mantle are close to or at the lunar surface in many large impact basins (e.g., Crisium, Apollo ...

Eruption Age of a Pleistocene Basalt From ^(40)Ar-^(39)Ar Analysis of Partially Degassed Xenoliths [PDF]
, 1983 We have applied ^(40)Ar−^(39)Ar dating to potassium-rich granitic xenoliths and host basalt from the Pleistocene Big Pine volcanic field, California. These xenoliths had been partially degassed upon their inclusion in the basaltic lava.

Acta Geologica Sinica - English Edition, EarlyView.ABSTRACT The Jinqingding gold deposit in eastern Jiaodong is a significant gold mineralization within the Muping–Rushan metallogenic belt. This study integrates structural analysis and trace element geochemistry of sulphides to elucidate ore‐controlling mechanisms and metallogenic models.

Distribution of Fenitized Crustal Xenoliths in Carbonatite Intrusions, West-Central Arkansas [PDF]
, 1981 Crustal xenoliths from carbonatite intrusions in the Morrilton-Perryville Arkansas area display a variety of mineralogical and textural features that suggest that they are fragments of basement crystalline rock that has undergone sodic metasomatism ...

Revisiting the Hummeln structure, Sweden—A shallow marine Cambrian impact structure
Meteoritics &Planetary Science, EarlyView.Abstract Hummeln is a simple impact structure located in south‐eastern Sweden. It is approximately 1.2 km in diameter and almost completely covered by a lake. Here, we present the first detailed investigation of impactites and mapping of the 164.25 m deep drill core Hummeln‐1 with a focus on impact metamorphism and the impact process.

Eruption Age of a ~100,000-Year-Old Basalt From ^(40)Ar-^(39)Ar Analysis of Partially Degassed Xenoliths [PDF]
, 1984 We have applied ^(40)Ar-^(39)Ar dating, using stepwise thermal extraction of Ar, to five potassium-rich granitic xenoliths and their host basalt from Sawmill Canyon in the Sierra Nevada, California.

Table Cape vent xenolith suite, northwest Tasmania: Mineralogy and implications for crust-mantle lithology and Miocene geotherms in Tasmania. [PDF]
, 2005 The Miocene Table Cape vent erupted a diverse mantle-crust xenolith suite within its fractionated nephelinitic matrix. Assemblages include mantle metaperidotites, garnet-metawebsterites and rarer garnet-metadinopyroxenitcs, garnct-mctawehrlites ...
