A Permian intermediate-sulfidation epithermal Pb–Zn–Ag deposit in the northern margin of North China Craton

Ore Geology Reviews, 2023
Recent Pb-Zn-Ag exploration in the northern margin of North China Craton has made significant new discov-eries. Here we report one Pb-Zn-Ag deposit in the Shaolanghe orefield with typical signatures of intermediate-sulfidation epithermal deposits ...

Geology, geochronology, and geochemistry of the Sinongduo Ag–Pb–Zn deposit in the Gangdese metallogenic belt: Implications of intermediate sulfidation mineralization in the Linzizong volcanic succession

Ore Geology Reviews, 2020
Abstract The Sinongduo Ag–Pb–Zn deposit was first defined as a typical low sulfidation (LS) epithermal deposit in the widespread Linzizong volcanic succession (LVS), Gangdese belt, Tibet. This paper we describe the lithology, mineralization, and hydrothermal alteration based on current advances in exploration, and use multiple chemical and ...

Intermediate sulfidation epithermal mineralization of No. 4 anomaly of Golojeh deposit (N. Zanjan) based on mineralography, alteration and ore fluid geochemistry features

Journal of Economic Geology, 2014
The base (Cu–Pb–Zn) and precious metals (Ag±Au) mineralization at the No. 4 anomaly of Golojeh deposit occurred in volcanic and sub–volcanic Eocene–Oligocene host rocks, in the central part of the Tarom–Hashtjin zone.

Geochemistry and petrogenesis of granitoid rocks in the Tarom-Hashtjin metallogenic province, western Alborz [PDF]

پترولوژی, 2023
The Cenozoic magmatism is mainly concentrated in the Alborz magmatic arc, Urumieh-Dokhtar magmatic arc, Central and Eastern Iran. The Western Alborz magmatic arc known as Alborz-Azerbaijan is hosted numerous porphyry-epithermal deposits.

Fluid inclusion, zircon U-Pb geochronology, and O-S isotopic constraints on the origin and evolution of ore-forming fluids of the tashvir and varmazyar epithermal base metal deposits, NW Iran

Frontiers in Earth Science, 2022
Tashvir and Varmazyar deposits are part of the epithermal ore system in the Tarom–Hashtjin Metallogenic Belt (THMB), NW Iran. In both deposits, epithermal veins are hosted by Eocene volcanic-volcaniclastic rocks of the Karaj Formation and are spatially ...

Genesis of the Varmazyar Pb-Zn (Ag) occurrence, Tarom-Hashtjin metallogenic belt: Insights from ore geology, geochemistry and fluid inclusion studies

Journal of Economic Geology, 2022
Introduction Varmazyar Pb–Zn (Ag) occurrence, 65 km north of Zanjan, is located in the Tarom–Hashtjin metallogenic belt (THMB). The THMB has been recognized as one of the most important epithermal metallogenic belts in Iran (Kouhestani et al., 2018b ...

Genesis of Tozlou Pb-Zn Occurrence (South of Zanjan): Evidence from Geology, Mineralization, and Geochemistry

Journal of Economic Geology, 2023
Tozlou Pb-Zn mineralization, ~250-300m long, and ~50m thick, is hosted by limestone units of the Qom Formation. The main mineralization zone occurred as vein-veinlets and vug infill textures, where mineralization is observed as Pb-Zn-bearing barite veins
