Geochronological and Geochemical Constraints on the Petrogenesis of Lamprophyre from the Giant Weishan REE Deposit in China

Minerals (Basel, Switzerland), 2022
The Weishan REE deposit is located in the southwest of the Luxi Terrane of the North China Craton (NCC), where a large number of lamprophyre dikes are spatially exposed with the deposit.

Constraints from lamprophyre petrogenesis on the timing of Eocene lithospheric thinning and associated rifting of Borneo and Sulawesi

Journal of Asian Earth Sciences
The petrogenetic history of well characterised magmatic rocks may contain invaluable information of paleo-lithospheric thickness and structure that can inform on tectonic evolution.

Mineralogical and geochemical characterization of a rare ultramafic lamprophyre in the Tandilia belt basement, Río de la Plata Craton, Argentina [PDF]

Journal of South American Earth Sciences, 2013
A metre-thick ultramafic lamprophyre dyke intrudes the basement of the andilia belt at the Sierra Alta de Vela, Argentina. A petrological and geochemical study of this rock and associated small dykes indicates a predominantly calc-alkaline trend ...

The “Lamprophyre Clan” Revisited

Journal of the Geological Society of India, 2022
Abstract A sequential genetic diagram is proposed for lamprophyres adopting their definitions, classification, petrological and geochemical signatures from an elaborated literature survey. Based on the definition of individual lamprophyric types, the existence of “Lamprophyre clan” of rocks is supported as it was first proposed by Rock ...
