Skarns at a peridotite contact, Neyriz, Iran: High-temperature melting and metamorphism in a forearc setting

Geosystems and Geoenvironment, 2023
In the Neyriz area of southern Iran unusual skarns are found above serpentinised peridotites at the contact with crystalline limestones. They have been interpreted as the high-temperature product of intrusion by hot peridotite into limestones, as low ...

Genetic relation between skarn mineralization and petrogenesis of the Darreh Zerreshk granitoid intrusion, southwest of Yazd‫ ‬

Journal of Economic Geology, 2012
Most skarn deposits are directly related to magmatic activity, and there is a systematic correlation between composition of causative plutons and the metal contents of the related skarns.
