Lamprophyres of the Peshchernoe gold deposit, their geological position, material composition, and metasomatic alterations (Northern Urals)

Записки Горного института
The article presents the first data on biotite-hornblende lamprophyres discovered at the Peshchernoe gold deposit. We consider the geological position of lamprophyre dikes in the deposit structure and the relationship of these rocks with tectonically ...

Petrology and dating of the Permian lamprophyres from the Mal? Fatra Mts. (Western Carpathians, Slovakia)

, 2018
Calc-alkaline lamprophyres are known from several localities in the Mal? Fatra Mountains. They form dykes (0.5-3 m) of varying degree of alteration that have intruded the surrounding granitoid rocks which are often incorporated xenoliths. Clinopyroxenes (
