Magmatic rocks containing economic concentrations of iron, titanium, vanadium and
phosphorous are commonly associated with massif-type anorthosites and related rocks. This …

IGNEOUS ROCKS AND PROCESSES A practical introduction to igneous petrology for
students and practitioners The newly revised Second Edition of Igneous Rocks and …

At the assumed core of reconstructed Rodinia, northern Laurentia, comprising the Canadian
Shield (including Greenland) and its buried western and northern extensions beneath …

The titanium concentrations of 484 zircons with U-Pb ages of∼ 1 Ma to 4.4 Ga were
measured by ion microprobe. Samples come from 45 different igneous rocks (365 zircons) …

The Late Paleozoic to Early Mesozoic mafic–ultramafic complexes from the northern North
China Block (NCB) are used to constrain the isotopic composition and evolution of mantle …

New zircon U–Pb dating results on the Carboniferous–Permian volcanic rocks in the
northern margin of the North China block (NCB) indicate their eruption during the Early …

In recent years, a rapidly expanding database, especially in sensitive high-resolution ion
microprobe (SHRIMP) geochronology, has led to significant advances in understanding of …

In situ Li analyses of 4348 to 3362 Ma detrital zircons from the Jack Hills, Western Australia
by SIMS reveal that the Li abundances (typically 10 to 60 ppm) are commonly over 10,000 …

We report the U-Pb age distribution of detrital zircons collected from central and southern
Appalachian foreland basin strata, which record changes of sediment provenance in …

The compositions, textures, associated rocks and tectonic environments of anorthosites
allow categorization into six different types, some of which show distinct age-restrictions in …
