Rare earth elements (REEs) are considered critical metals globally. About 62% of the global
resources of REEs occur associated with carbonatites and alkaline complexes. However …

Based on the field relations, associated rock types and age, the carbonatite-alkaline rock
complexes of India, that are spatially related to deep main faults, rifts and shear zones, have …

Abstract Rare Earth Elements (REE) form critical raw materials in environment-friendly, high-
technology devices and components, and therefore have been classified as “critical …

We report an integrated field, petrographic, and geochemical study of three major
Cretaceous carbonatite annular occurrences from the Oulad Dlim massif (Adrar Souttouf …

This paper reports new zircon U–Pb ages and Hf isotopic compositions of felsic units of the
Abor volcanic rocks (AVR) of Eastern Himalayan Syntaxis (EHS), Northeast India, and …

Age-progressive volcanic chains are generally considered as surface expressions of deep-
rooted mantle plumes, whereas non-age progressive volcanic groups or solitary volcanic …

We report new U–Pb zircon ages for mafic plutonic (gabbro) and volcanic (andesite) rocks,
along with the whole-rock chemistry of a mafic–felsic suite of volcanic rocks from the Siang …

A comprehensive mineralogical, geochemical and isotopic review of six ultramafic-alkaline-
carbonatite magmatic intrusions of the Shillong Plateau (Sung Valley, Jasra, Swangkre …

New in-situ U–Pb ages and Sr–Nd–Hf isotopic data on mineral phases of the Sung Valley
and Jasra ultramafic-alkaline-(carbonatite) intrusions (Shillong Plateau, India) shed new …

Carbonatite-associated rare earth element (REE) deposits (CARD) are mainly found at the
edges of cratons in the rift or post-collisional settings, but only a minority carbonatite can …
