Igneous intrusions may move upwards through the crust by zone melting, by penetrative intrusion, by sloping or by some combination of these three mechanisms. Each mechanism offers different opportunities for contamination of the magma by country rock. Both zone melting and sloping offer the greatest possibility of assimilation, but in most natural situations the maximum amount of country rock assimilable by a magma is considerably less than its own original volume. Thermal and other constraints…

Geochemical and other evidence shows that granite magmas are generally derived from a mixture of melted crust and mantle material and the existence of a spectrum of types varying from largely

Summary Continental lower crust comes in a limited number of types that are best distinguished tectonically. Lower crust is formed primarily in oceanic or continental zones of lithospheric plate
Contrasting mechanisms for crustal sulphur contamination of mafic magma: evidence from dyke and sill complexes from the British Palaeogene Igneous Province
The addition of crustal sulphur to magma can trigger sulphide saturation, a process fundamental to the development of some Ni–Cu–PGE deposits. In the British Palaeogene Igneous Province, mafic and
Numerical Modelling of Melting Processes and Induced Diapirism In the Lower Crust
SUMMARY The processes of partial melting and magmatic diapirism within the lower crust are evaluated using a numerical underplating model. Fully molten basalt (T= 1200°C) is emplaced at the Moho
Proterozoic Anorthosite Massifs
Major anorthositic massifs intruded stable cratonic crust in the North Atlantic region about 1.4 to 1.7 Ga ago. Similar (meta-) anorthosite massifs (0.9–1.6 Ga) in Grenville and Sveconorwegian
A laboratory model for melting erosion of a magma chamber roof and the generation of a rhythmic layering
A hot magma chamber can ascend by melting the roof rock, a process which in turn affects the magma composition. The disaggregated mineral particles which consisted the roof rock will descend in the
O-Sr isotopic variations in Miocene granitoids from the Aegean: evidence for an origin by combined assimilation and fractional crystallization
Sr, O, and D/H isotopic compositions have been analyzed in Miocene metaluminous to slightly peraluminous (I-type) granitoids of the central Aegean. Individual plutonic complexes display significant

Thermal effects of basalt on continental crust and crustal contamination of magmas
A simple conduction-based heat-flow model is used to calculate the thickness of zones of continental crustal rock adjacent to basalt sheets which are raised to the temperatures of (1) hydrous mineral
The nature, ascent and emplacement of granitic magmas
The address is a wide-ranging commentary on the physical aspects of granitic magma and deals especially with the mode of emplacement. Recommendations on the nomenclature of plutons and batholiths

Recent developments in petrology indicate that fluid dynamic effects are of fundamental importance in controlling magma genesis. The forms of convection in magma chambers arise from compositional
Geochemistry of the Adamello massif (northern Italy)
The Tertiary Adamello massif, outcropping over an area of more than 550 km2 in the southern Alps (northern Italy) is composed mainly of granitoid rocks (granodiorite, tonalite, quartz diorite) with
Correlation between strontium and oxygen isotopic compositions of rocks from the Adamello massif (Northern Italy)
AbstractRock samples from the lithologic units forming the Adamello massif were analyzed for Rb and Sr concentrations and for87Sr/86Sr and18O/16O ratios. The most important features are as
