Geology mineralogy, structure and texture of Agh-Otagh base- precious metal mineralization (North Takab) [PDF]

پترولوژی, 2017
The Agh-Otagh mineralization area in the north of Takab, was formed within the andesistic tuffaceous rocks of the Oligo- Miocene age. Mineralization include polymetallic (Cu-Pb-Zn-Au-Ag) quartz veins and silicified zones, which occurred as breccia and ...

In-situ trace element and S isotope systematics in pyrite from three porphyry-epithermal prospects, Limnos Island, Greece

Frontiers in Earth Science, 2022
Porphyry-epithermal systems associated with high-K calc-alkaline to alkaline igneous host rocks may be prospective for the recovery of Te among related elements like Cu, Ag, and Au. Limnos Island, as part of the Tethyan magmatic belt, is such an example,

Mineralogy and distribution of critical elements in the Sn–W–Pb–Ag–Zn Huanuni deposit, Bolivia [PDF]

, 2019
The polymetallic Huanuni deposit, a world-class tin deposit, is part of the Bolivian tin belt. As a likely case for a “mesothermal” or transitional deposit between epithermal and porphyry Sn types (or shallow porphyry Sn), it represents a case that ...

Development and dosimetric evaluation of a freely deformable ⁶Li-based neutron shield for boron neutron capture therapy. [PDF]

Med Phys
Abstract Background Boron neutron capture therapy (BNCT) enables selective tumor irradiation by exploiting the high‐linear energy transfer particles generated from neutron interactions with 10B atoms. BNCT has been approved as an insurance‐covered medical treatment for recurrent head and neck cancer in Japan.

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 ...

Hydrothermal alteration, mineralization and fluid inclusions in the Pista and Fofão prospects: implications for the genetic model of the Coringa polymetallic deposit, SE Tapajós Mineral Province, Amazonian Craton, Brazil

Journal of the Geological Survey of Brazil, 2020
Pista and Fofão are a prospect located near the main orebodies of the Coringa polymetallic deposit, in southeastern Tapajós Mineral Province of the Amazonian Craton. In both prospects, the mineralization is hosted in an Orosirian alkali feldspar granite,
