Thermobarometry of quartz diorite porphyry bodies and investigation of genesis of related skarn using mineral chemistry data in Tighanab area, southeast of Sarbisheh (east of Iran) [PDF]

پترولوژی, 2021
In Tighanab area at southeast of Sarbisheh, the intrusion of quartzdioritic subvolcanic bodies into the Paleocene- Eocene limestone and sandstone led to the skarn formation. Plagioclase, hornblende (magnesiohornblende) and quartz are the main minerals in

Mineralogy and skarnification processes at the Avan Cu-Fe Skarn, northeast of Kharvana, NW Iran

Journal of Economic Geology, 2017
Introduction The Avan Cu-Fe skarn is located at the southern margin of Qaradagh batholith, about 60 km north of Tabriz. The Skarn-type metasomatic alteration is the result of Qaradagh batholith intrusion into the Upper Cretaceous impure carbonates.

Paragenesis relations study of wollastonite – pyroxene – garnet mineral assemblage in Vejeh Skarn (North East Isfahan) [PDF]

پترولوژی, 2017
The Vejeh Skarn is located at 70 km Northeast of Isfahan. The Vejeh intrusive body with granodiorite to tonalite composition have been intruded the lower Cretaceous marl carbonate which caused the formation of skarn rocks.

Tin-bearing magnetite with nanoscale Mg-Si defects: Evidence for the early stages of mineralization in a skarn system

Frontiers in Earth Science, 2023
Tin-bearing magnetite is reported from several types of magmatic-hydrothermal ore deposits. The question of whether tin is incorporated within solid solution, as Sn4+, or as nanoinclusions remains open, however.

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, EarlyView.
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 ...

Petrogenesis and Geochemistry of REE of Intrusive Rocks, Skarn Zone, and Iron Ore of Shotorsang, Northwest of Neyshabour

Journal of Economic Geology, 2023
Shotorsang iron skarn is located in 60 km northwest of Neyshabour (Khorasan Razavi, Iran) in Quchan-Sabzevar magmatic belt. Subvolcanic intrusion rocks have intruded into Cretaceous limestones and created skarnization.
