Geological and geochemical studies of gold mineralization in Bode-Saadu axis, Southwestern Basement Complex, Nigeria have been conducted order to study their mode occurrence, structural settings, pattern distribution potential. reveal that granite gneiss are the prominent rocks area exist north-eastern, north-western southwestern part whereas mica amphibole schist occur as low-lying exposure. P...

Gold production in New Zealand has been significant since the mid 1800s, totalling 900 t (29 Moz) to 2005. In addition, there is potential for a further 1230 t (39.5 Moz) of gold in known and undiscovered deposits. Most of the gold has originated from epithermal and mesothermal (orogenic) hydrothermal systems. Epithermal gold occurs in the Northland, Coromandel and Taupo volcanic zones in quart...

The legendary wealth in gold of ancient Egypt seems to correspond with an unexpected high number of gold production sites in the Eastern Desert of Egypt and Nubia. This contribution introduces briefly the general geology of these vast regions and discusses the geology of the different varieties of the primary gold occurrences (always related to auriferous quartz mineralization in veins or shear...

the takmeh-dash region comprises a wide variety of igneous bodies that have been developed from early to late neogen. the granitic rocks and related aplite apophyses have been developed along fault-dominated structures which defines a well pronounced mineralized zone. according to isotopic and fluid inclusion studies, most of the quartz-pyrite units are solution-related with some traces of cu, ...

In the last decades, helicopter-borne electromagnetic (HEM) method became a focus of interest in the fields of mineral exploration, geological mapping, groundwater resource investigation and environmental monitoring. As a standard approach, researchers use 1-D inversion of the acquired HEM data to recover the conductivity/resistivity-depth models. Since the relation between HEM data and model ...

The Jagpura Au-Cu deposit is situated within the Aravalli craton in northwestern part of India. In present work, petrography, mineral chemistry, fluid inclusion and sulfur isotopic compositions were used to study deposit. ore association arsenopyrite, loellingite, chalcopyrite, pyrrhotite pyrite, along with native gold, magnetite apatite. gold fineness ranges from 914–937‰ (avg. 927‰). presence...

The Lut Block is a potential porphyry-style mineralized region in Iran including the well-explored Shadan porphyry gold-copper deposit, which has an extensive zone of gold- and copper-bearing stockwork-like sheeted veins. structural setting this deposit key to understanding genesis mineralization. Our field studies show that mineralization occurs as steeply dipping ore bodies along NW–SE transp...
