Magmatic and tectonic processes can transport large volumes of magma generated in the deep crust as discrete pulses to shallower crustal depths, resulting incremental construction large, composite batholiths over thousands tens millions years. The Silurian Early Devonian Donegal batholith Ireland is a classic example which regional geological syntheses lithogeochemical data show that emplacemen...

Kudz Ze Kayah (KZK) and Wolverine are volcanogenic massive sulphide deposits hosted by Early Mississippian meta-rhyolites, marine metasedimentary rocks and intermediate to mafc metatuffs of the Yukon Tanana Terrane in the Simpson Range, southern Yukon (Figure I). This project aims to pinpoint, within central northern B.C., stratigraphy favorable to the formation of Early Mississippian volcanoge...

In southeastern British Columbia many inhusive suites lack conclusive radiometric age dates. The purpose of this BSc. project is to study three of the intrusions in the Purcell Mountain Range and provide uranium-lead geochronological results on two of these to refme the igneous magmatic history of the region. The White Creek Batholith (WCB) and the Greenland Creek Stock (GCS) are located approx...

Significant magnetite, in the form of dyke-like lodes (Cockfield. 1948). occurs in close spatial relationship to copper deposits such as the Afton mine. The genetic relationship of these massive magnetite lodes to the copper deposits of the Iron Mask is unknown, as i s the origin of the magnetite deposits. However, the proximity of these deposits to magnetite-rich intrusive units of the Iron Ma...

An integrated study involving whole-rock and Sr–Nd–Hf isotope geochemistry and zircon geochronology and trace element combined with detailed field investigation was carried out for the composite Meiwu batholith in the West Qinling orogenic belt of central China to probe the origins of its compositional diversity and its emplacement history. The batholith is composed of quartz diorite, granodior...

Slab rollback during subduction plays a key role in controlling continental growth at convergent plate boundaries. The dynamics of currently subducting slabs can be precisely constrained using geophysical techniques. In contrast, ancient episodes slab difficult to constrain, yet are critical unlocking the tectonic evolution long-lived orogens such as Phanerozoic Australian Tasmanides eastern Go...
