Abstract The Juomasuo Au–Co deposit, currently classified as an orogenic gold deposit with atypical metal association, is located in the Paleoproterozoic Kuusamo belt northeastern Finland. volcano-sedimentary sequence that hosts was intensely altered, deformed, and metamorphosed to greenschist facies during 1.93–1.76 Ga Svecofennian orogeny. In this study, we investigate temporal relationship b...

This paper is the first attempt to study mineralogical and geochemical features of mineralization hosted within volcanic rocks Baska Piwaza section, at Halgurd Mountain, which highest mountain in Kurdistan whole Iraq. The host lithologies studied section represent mostly (basalts andesites), secondary sedimentary lithologies, such as radiolarian chert. There are two main stages oxide sulfide th...

The Igoudrane mine with a total production of 700,000 t ore grading 485 g/t Ag is currently one the most productive mines in Imiter district eastern Anti-Atlas Morocco. silver-rich ± base metal deposit occurs dominantly as vein- and hydrothermal breccia-hosted orebodies at interface between lower Ediacaran turbidites Saghro Group unconformably overlying, felsic volcanic, volcaniclastic rocks la...

Undoubtedly, involving more tools, datasets, and techniques for detecting the mineralized areas sharply narrow zones to be investigated delivered, in most cases highly potential zones. Consequently, this study is an attempt apply remote sensing data including Sentinel 2 ASTER, field observations, petrography of hydrothermal alteration processes, ore microscopic investigations, X-ray examination...

This study evaluates the geological attributes of rocks within Abu Ghalaga area using spatial, geochemical, and petrographic approaches. ASTER Landsat imagery processed band ratio principal component analysis were used to map hydrothermal alterations, while a regional tectonic evaluation was based on automated extraction lineaments from digital elevation model. Geochemical analyses then employe...

the cheshmeh hafez polymetal deposit is located in troud – chahshirin mountain range in southeastern damghan. in this province, the volcanism and associated mineralization are closely related to major faults anjilo and troud with nw-se trend. the exposed rocks in the study area consist of volcano clastic sequence of sandstone, tuff, volcano breccias and mostly andesitic and andesitic- basalt fl...

The Sungun porphyry copper deposit is located in northwestern Iran and is associated with diorite/granodiorite to quartz-monzonite of Miocene age, which intruded Eocene volcanosedimentary and Cretaceous carbonate rocks. Copper mineralization was accompanied by both potassic and phyllic alteration. Three main mineralization related alteration episodes (potassic, transition, and phyllic alteratio...
