Porphyry Deposits of the Urals: Geological Framework and Metallogeny

open access: yesOre Geology Reviews, 2017
Most of the Cu (± Mo,Au) porphyry and porphyry-related deposits of the Urals are located in the Tagil-Magnitogorsk, East-Uralian Volcanic and Trans-Uralian volcanic arc megaterranes.

Fluid inclusions technique for porphyry deposit exploration: The Rosario porphyry Cu-Mo deposit

2023
Porphyry ore deposits are the largest source of copper, molybdenum, gold, and silver in the world. Various exploration techniques have been developed due to their importance as a source of metals. A special focus has been devoted to understanding the processes of hydrothermal fluids as mineralization drivers. Fluid inclusions provide direct information

Geology and Origin of the Post-Collisional Narigongma Porphyry Cu–Mo Deposit, Southern Qinghai, Tibet

open access: yesGondwana Research, 2014
Narigongma is a poorly studied Mo-rich (similar to 0.06 wt.%) post-collisional porphyry Cu deposit located in southern Qinghai Province, Tibet, 400 km northwest of the Yulong porphyry Cu-Mo-Au belt.

Porphyry CU deposits in the Central Andes of Argentina: An overview

Journal of South American Earth Sciences, 2021
Abstract Porphyry Cu deposits are the world's most important source of Cu and the Central Andes of South America hold some of the largest Cu resources worldwide. In Argentina many porphyry-type deposits and prospects with different degrees of exploration straddle along ~1500 km of the Central Andes.

Porphyry type deposits associated with adakite magmas: Case study of porphyry Cu-Au and Cu-Mo deposits in mongolia

Ifost, 2013
Major porphyry type deposits are spatially and temporally associated with adakitic magmas. Such magmas show high Sr/Y, high Al2O3, and high La/Yb geochemical signature. Case study of late Devonian Oyu Tolgoi and Carboniferous Shuteen deposits show that porphyry Cu-Au are associated with oxidized, high Sr/Y mafic-inermediate adakitic magma.

Role of Potassic Alteration for Porphyry Cu Mineralization: Implication for the Absence of Porphyry Cu Deposits in Japan

Resource Geology, 2018
Abstract The role of potassic alteration and associated quartz veins for porphyry Cu mineralization in two representative porphyry systems (El Salvador, Chile, and Grasberg, Indonesia) was examined to evaluate the potential of porphyry Cu mineralization in Japan.

The Origin of Cu/Au Ratios in Porphyry-Type Ore Deposits

Science, 2002
Microanalysis of major and trace elements in sulfide and silicate melt inclusions by laser-ablation inductively coupled plasma mass spectrometry indicates a direct link between a magmatic sulfide liquid and the composition of porphyry-type ore deposits.

Porphyry-Cu Deposits of Turkey

2019
Turkey, located within the western Tethyan-Eurasian Belt contains numerous porphyry copper deposits formed by the subduction, collision and post-collisional events during the closure of NeoTethys Ocean between the latest Cretaceous and late Miocene. These porphyry systems and associated epithermal and skarn deposits are associated with the subduction ...

Cu diffusivity in granitic melts with application to the formation of porphyry Cu deposits

Contributions to Mineralogy and Petrology, 2018
We report new experimental data of Cu diffusivity in granite porphyry melts with 0.01 and 3.9 wt% H2O at 0.15–1.0 GPa and 973–1523 K. A diffusion couple method was used for the nominally anhydrous granitic melt, whereas a Cu diffusion-in method using Pt95Cu5 as the source of Cu was applied to the hydrous granitic melt.

The key role of volatile-rich magma replenishment in the formation of porphyry Cu-Mo deposits: A case study of Gangjiang porphyry Cu-Mo deposit, Tibet

Acta Petrologica Sinica, 2021
西藏冈底斯带中段的岗讲斑岩铜-钼矿床发育多期次侵入体,而成矿作用主要与其中一期岩体(流纹英安斑岩)密切相关。为探究其原因,本文对岗讲斑岩铜-钼矿床中发育的各期次侵入体进行了全岩主、微量元素分析,并重点研究各期次侵入体内部新鲜斑晶(黑云母、斜长石)和副矿物(锆石、磷灰石)的化学成分和结构特征。结果表明,矿区各期次侵入岩均属于高钾钙碱性系列,具有相近的锆石饱和温度,都来自较为氧化的岩浆。此外,相比其他期次侵入岩,主成矿期的流纹英安斑岩中的磷灰石具有较高的SO3、Cl含量,较低的F含量;黑云母含有较高的Cl含量和较低的F含量;同时,斜长石发育反环带。这些证据表明,在主成矿期岩浆就位之前,存在富S、Cl的偏基性岩浆注入了深部岩浆房,并发生岩浆混合作用,这不仅导致了主成矿期斑岩体的就位 ...
