The campsite dykes: A window into the early post-solidification history of the Skaergaard Intrusion, East Greenland [PDF]

, 2016
publication-status: Publishedtypes: ArticleThis is an open access article.The Skaergaard Intrusion of East Greenland is cut by several generations of dykes, the earliest of which is thought to have intruded shortly after solidification of the Skaergaard.

Nature and Composition of the Lower Continental Crust in Central Spain and the Granulite–Granite Linkage: Inferences from Granulitic Xenoliths [PDF]

, 1999
Xenolith-bearing alkaline ultrabasic dykes were intruded into the of the Hercynian basement of the Spanish Central System in early Mesozoic times. The suite of lower-crustal xenoliths in the dykes divided into three groups: felsic peraluminous granulites,

The Mantle and Basalt-Crust Interaction Below the Mount Taylor Volcanic Field, New Mexico [PDF]

, 2010
The Mount Taylor Volcanic Field (MTVF) lies on the Jemez Lineament on the southeastern margin of the Colorado Plateau. The field is centered on the Mt. Taylor composite volcano and includes Mesa Chivato to the NE and Grants Ridge to the WSW.

The Nitrogen Budget of Earth

, 2015
We comprehensively compile and review N content in geologic materials to calculate a new N budget for Earth. Using analyses of rocks and minerals in conjunction with N-Ar geochemistry demonstrates that the Bulk Silicate Earth (BSE) contains \sim7\pm4 ...

Magmatic inclusions in the search for natural silicate-salt melt immiscibility: methodology and examples [PDF]

, 2003
Immiscible phase separation during the cooling and crystallisation of magmas is an inherently fugitive phenomenon and melt inclusions may provide the only remaining evidence of this process. We detail those features of such inclusions that can both prove

Modes of Occurrence of Spinel in Xenoliths.,

The Journal of the Geological Society of Japan, 1949
During his petrological study on the inclusions in the garnet-biotite-andesite from Nijo Volcano near Osaka, the present writer pointed out the common occurrence of spinel associating intimately with porphyroblastic andalusite or sillimanite in some xenoliths derived from argillaceous metamorphic rock, as the feature to be observed in xenoliths when ...

Sub-Zero Alteration in an Isotopically Heavy Brine Preserved in a Pristine H Chondrite Xenolith [PDF]

Introduction: Brecciated H chondrites host a variety of xenoliths, including unshocked, phyllo- silicate-rich carbonaceous chondrites (CCs). The brecciated H chondrite Zag (H3-6) is one of two chondrites to host macroscopic (1 - 5mm), xenolithic crystals
