Peralkaline igneous rocks are defined by a molar (Na+ K)/Al ratio> 1 and are subdivided into
miaskitic and agpaitic varieties depending on their mineralogy. In the more common …

Magmatic evolution creates crystal cumulates. In the current paradigm for the genesis of
evolved magmas, cumulate crystal mushes dominate trans-crustal magma systems that feed …

The idea for a book on anorthosites came to me in January of 1986 while returning to
Houston after holiday festivities in Dallas. The original idea was a review paper on …

The Panzhihua gabbroic layered intrusion is associated with the 260 Ma Emeishan Large
Igneous Province in SW China. This sill-like body hosts a giant Fe–Ti–V oxide deposit with …

From GF Becker's and LV Pirsson's early enunciations linking the dynamics of magma
chambers to the rock records of sills and plutons to this day, two features stand at the centre …

Granites in both crystalline terranes and continental magmatic arcs tend to be circular to
elliptical in map view and vary in width from about 3 to 100 km. Available gravity and …

Layered intrusions are fossilized natural laboratories that historically have constrained many
fundamental principles of igneous petrology. Layered intrusions are typically stratiform …

Abstract The Paleoproterozoic Bushveld Complex, including the world's largest layered
intrusion and host to world-class stratiform chromium, platinum group element, and …

Although there are numerous publications on the geology of high-grade gneiss terrains, few
descriptions exist of how to map and carry out structural analysis in these terrains. Textbooks …

Abstract The Neoarchean Stillwater Complex, one of the world's largest known layered
intrusions and host to a rich platinum-group element deposit known as the JM Reef …
