Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

We recognize eight types of ferroan granitoid that can be distinguished on the basis of major
element chemistry. These include alkalic granitoids that may be metaluminous or …

Pseudosection modelling is rapidly becoming an essential part of a petrologist's toolkit and
often forms the basis of interpreting the tectonothermal evolution of a rock sample, outcrop …

Recent crystallographic data indicate that in biotite Ti orders preferentially onto the M2
octahedral site rather than onto the M1 site as assumed in previous solution models for K2O …

Abstract The Bushveld Complex, South Africa, is the world's largest layered intrusion and
host to the majority of the known resources of platinum group elements, chromium, and …

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

A new empirical method has been devised for classification of mantle-derived garnets in
kimberlite. Simple chemical screens have been developed to distinguish between garnets …

High-grade rocks occur in the Chinese Altai, but the timing of metamorphism is poorly
constrained, which hinders our understanding of the thermo-tectonic history of the region …

Metamorphic zones in the Chinese Altai orogen have previously been separated into the
kyanite-and andalusite-types, the andalusite-type being spatially more extensive. The …

Layered intrusions crystallize mainly from basaltic magma to form large bodies of igneous
rocks that exhibit prominent layering and they preserve stunning rock records of the …
