Comparison of mineralization of the Sungun and Kighal porphyry copper deposits, NW Iran: with an emphasis on fluid inclusion studies

Journal of Economic Geology, 2019
Introduction Nowadays, more than half of the word’s copper production is obtained from porphyry copper deposits, large (greater than 100 Mt), low- to moderate-grade, disseminated, stockwork-veinlet, carrying at least trace elements, such as molybdenum ...

Geodynamic Significance of Intraplate Basaltic Magmatism From the Western Mediterranean Region

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Dynamic topography changes as mantle convection evolves, making its past surface expression difficult to reconstruct. Widespread Neogene‐Quaternary intraplate basaltic magmatism across the Western Mediterranean Region allows us to test whether dated basalts preserve the mantle thermal structure responsible for regional dynamic support.

Zircon LA-ICP-MS U-Pb Ages and the Hf Isotopic Composition of the Ore-Bearing Porphyry from the Yanghuidongzi Copper Deposit, Heilongjiang, China, and Its Geological Significance

, 2019
The Yanghuidongzi copper deposit is a typical porphyry copper deposit located at the eastern margin of the Xing’anling-Mongolian Orogenic Belt (XMOB). While much attention have been paid to the ore-forming age of the deposit and the magma source of

Geochemical and Geological Investigation of Skarn‐Type Pb–Zn Mineralization in Hastanetepe (Balya‐Balıkesir, Türkiye): An Approach Based on Fluid Inclusions, Sulphur Isotopes and Geochemical Data

Geological Journal, Volume 61, Issue 9, Page 2940-2957, September 2026.
Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...

Geochemical fingerprinting of typical giant deposits in the Central Asian metallogenic domain: case studies of the Muruntau gold deposit and the Almalyk porphyry copper deposit

Dizhi lixue xuebao
Objective  The Central Asian Metallogenic Domain is rich in mineral resources. Geochemical metal-content surveys conducted during the Soviet era led to the discovery of the Muruntau gold deposit, the world’s second-largest gold deposit, and the Almalyk ...

Why Does the Broken Hill Deposit Sit in Resistive Crust? Magnetotelluric Evidence for Metamorphic Decoupling of a World‐Class Mineral System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The spatial association between electrical conductors and ore deposits underpins the widespread use of magnetotellurics (MT) in mineral exploration, yet not all mineral systems preserve a diagnostic conductive signature. Here, we present a high‐resolution MT study of the region hosting the world‐class Broken Hill Pb‐Zn‐Ag deposit (NSW ...

Metal scavenging by sulfide oxidation in porphyry copper deposit root zones

Communications Earth & Environment
Porphyry copper (-gold) deposits in both arc and non-arc settings are hosted by oxidized magmatic rocks, but the exact mechanism by which the source magmas of these non-arc deposits become oxidized remains obscure.
