We suggest the following scenario for the magmatic history of the Buchim–Damjan–Borov Dol ore district: a slab rollback of an oceanic slab located further to the SW which led to extensional and compressional features in upper levels of the continental crust. ... crust material in variable degrees during the ascent of the magma can explain ...

Processes of Magma Evolution and Magmatic Suit

Earth system. Magmatic processes and the evolution of magmas throughout geological history have shaped the globe by forming the continents and providing nutrient elements in abundances that have made them important in the metabolism of plants and animals. Without magmatism and the chemical differentiation of magmas, life as we know it

(PDF) Viscosity of high-K basalt from the 5th April 2003 .

Comparison of the Stromboli ascent rate estimation and various types of magma. Overall, ascent rates for kimberlites are higher than those for alkalibasalts and other magma types and are of the same order of magnitude when compared with the Stromboli basalt. Star symbol represent the data from the present study (8).

Stratigraphy and geochronology of the Nacientes del Teno .

Revised stratigraphy and new U-Pb geochronological data are reported for the Nacientes del Teno Formation and lowermost strata of the Río Damas Formation in Maule, Chile (∼35.15°S), a succession of sedimentary and volcanic rocks deposited along the western margin of the Neuquén backarc basin during the Middle to Late Jurassic (174–145 Ma).

CCFS 2015 - Res. Highligh

The ascent of kimberlite magmas to Earth‘s surface, therefore, requires unique conditions. To investigate the evolution of kimberlite magmas, we need phases that preserve geochemical signatures of magma interactions during transport through the mantle and the crust.

I conclude with a time and space model for the evolution of the fault zone as magma ascends the conduit, and how the fault zones evolve through time. The factors that contribute to the differences in conduit fault zone width and nature throughout the eruption are: 1) differences in ascent rates at the onset and origin of brittle failure, 2 ...
