three granitoid bodies, shirkuh batholith, kaffe abad and ader bolandan are exposed in nw yazd, cutting across the naiband formation (upper triassic), and overlain by cretaceous formations. shirkuh batholith is most likely of jurassic age. it seems to be the first and the most significant episode of magmatism in studied area which occurred in middle jurassic (late cimmerian) time. on the other ...

structural study by Glover (19%). His 1:25 000-scale map of the Sununit Pass area overlaps thc western pan of the Creston map. area and has been incorporated in this study (Figure 1). Stratigraphic divisions adopted by Glover (following those of Rice, 1941) are largely maintained here. A thesis by 13arrett (1982) describes structures in the Bayonne batholith, along the northern edge of the Cr...

the qom formation, which hosts the mazraeh celestite deposit, contains dominantly limestones, marl and subordinate evaporites deposited in shallow marine environments. petrographic evidence indicates that the celestite deposits were formed by replacement of limestone. the presence of carbonate inclusions within celestite crystals as well as the pseudomorphic habits of some crystals suggests tha...

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...
