The Mesozoic-Cenozoic Coastal Batholith of Peru is a multiple intrusion of gabbro, tonalite and granite occupying the core of the Western Cordillera over a length of 1600 km. Its structure and composition are described within the context of an intracratonic Andean zone in which vertical movements were dominant. The emplacement was controlled by growth-fractures on all scales and the magmas were channelled to high levels in the crust along a single mega-lineament, to be intruded finally as…

Abstract: SUMMARY: The Coastal Batholith of Peru, Lima segment, is a composite batholith made up of at least 8 time-separated magmatic events. The evolution of the batholith is such that the amount
The Sunnhordland batholith, W. Norway: regional setting and internal structure, with emphasis on the granitoid plutons
The Caledonian Sunnhordland batholith is composite, ranging in composition from gabbro to granite. The batholith constitutes the main part of the Tysnes Nappe, but granitic rocks which are thought to
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
A Petrographic and Chemical Section through the Northern Idaho Batholith
Petrographic and chemical study of a well-exposed section through the northern Idaho batholith documents a high degree of mineralogical and chemical homogeneity and suggests that all of the rocks
Caledonian plutonism in Britain: A summary
The Caledonian granites of Britain are a wide-ranging suite of pretectonic and posttectonic tonalite-granodiorite-granite intrusions which were emplaced in the time interval 650–380 Ma ago. The
The New England Batholith, Eastern Australia: Geochemical Variations in Time and Space
The New England Batholith, Australia, is part of the Upper Paleozoic New England Fold Belt, with most plutons intruded into the deformed trench-complex metasedimetary rocks in the southeast part of
The structure, petrology and geochemistry of the Tibchi younger granite ring-complex, Nigeria
The 1:50,000 geological map of the Tibchi Complex presented is characterised by a closed elliptical ring-dyke framework hitherto unpredicted by pioneer workers. Major rock units comprise a basalt


The Coastal Batholith of central Peru
A sector of the Peruvian Coastal Batholith 120 km long has been mapped in detail. Little altered volcanics of Cretaceous and Lower Tertiary age make up the bulk of the country rocks and these and
Segments and Super-Units in the Coastal Batholith of Peru
By analogy with rock-stratigraphic nomenclature the plutonic rocks of the linear Coastal Batholith of Peru can be grouped into units (formations) which can further be grouped into super-units
Ring complexes of the Peruvian Coastal Batholith: a long-standing subvolcanic regime
A special feature of the composite Coastal Batholith of Peru is the presence of ring complexes, which suggests a very high-level crustal environment and a direct connection between the magmas of the
Structural control of batholithic emplacement in Peru: a review
In the Andes, major lineaments controlled sedimentation, vulcanicity, batholithic intrusions and mineralisation throughout the Mesozoic and Cenozoic. These lineaments represent major fault lines in
On the Origin and Occurrence of Basic Bodies Associated with Discordant Bathyliths
Abstract It is suggested that the rock-suite, characteristic of the discordant bathyliths and ranging in composition from ultrabasic to ultra-acid, is formed from two magmas, a basaltic and a
On the rate of emplacement of batholiths
Determination of the rate of emplacement of batholiths is complicated by the complexity of a process involving segregation, intrusion and congelation, and by a lack of knowledge of the nature of
Sierra Nevada Batholith
The Sierra Nevada batholith is localized in the axial region of a complex faulted synclinorium that coincides with a downfold in the Mohorovicic discontinuity and in P-wave velocity boundaries within
Sierra Nevada Plutonic Cycle: Part I, Origin of Composite Granitic Batholiths
Intrusion of Mesozoic batholiths in California and the western North America Cordillera began in the Late Triassic 210 m.y. ago and ended in the Late Cretaceous 80 m.y. ago. Emplacement of granitic
Cauldron Subsidence and Fluidization: Mechanisms of Intrusion of the Coastal Batholith of Peru into Its Own Volcanic Ejecta
The Coastal Batholith of Peru shows how diorite, tonalite, granodiorite, and granite magmas rose through their last few kilometers by a process of magmatic stoping by their fluidized upper surface.
Cretaceous Stratigraphy of Central Andes of Peru
Cretaceous facies in Peru commonly fall into a lower, mainly clastic, group of formations and an upper group consisting of limestones, dolomites and shales. The clastic formations are largely
