The area of Esfordi-Zarigan in Central Iran is located in Bafq metallogenic province where most the rock units belong to Precambrian, Infracambrian and Cambrian periods. Although the sedimentary and volcanic rocks are widely distributed, this research is mainly focused on petrogenesis of plutonic rocks. From stratigraphic point of view sedimentary and volcanic rocks can be classified in five ma...

FEW analytical data exist for staurolite, in comparison with other metamorphic minerals such as garnet. However, using the microprobe, Hollister and Bence (1967) working with relatively inclusion-free specimens from the Kwoiek Area, British Columbia, established compositional zoning across staurolite in addition to compositional irregularities across sectoral twin boundaries. The staurolites st...

This paper deals with the geological mapping of late-Variscan Sàrrabus pluton, (south-eastern Sardinia), a shallow multiple and composite igneous complex dominated by several generations granodiorites, metaluminous peraluminous granites repeated pulses mantle-derived mafic magmas. The map has been compiled based on surveys at 1:10,000 1:5,000 scales, assisted in situ gamma-ray spectrometry deta...

During the COUIX of I :50 000 scale regional mapping in the Northern Selkirk Mountains (NTS 082M) various granitic rocks were sampled for U-Pb geochronology. This report presents new U-Pb data, interpreted ages, and the implications of these results for hvo such samples from the Selkirk Allochthon: the Downie Creek otihogneiss, and the Goldstream Pluto”. The Downie Creek orthogneiss consists of...

Abstract Late Paleozoic (Variscan) magmatism is widespread in Central Europe. The Lusatian Block located the NE Bohemian Massif and it part of Saxothuringian Zone Variscan orogen. It bordered by two major NW-trending shear zones, Intra-Sudetic Fault towards Elbe SW. scarce igneous rocks are situated close to these faults. We investigated 19 samples from plutonic volcanic Block, considering all ...
