The Maoniu** giant rare earth element deposit is genetically related to a Cenozoic
alkaline syenite–carbonatite complex. However, the origin of the alkaline complex and the …

In this work, a novel method is introduced to activate coal gangue (CG) for extraction of Si
and Al species. The activation experiments were carried out using a stainless steel tube …

Ultrapotassic rocks are volumetrically minor, but widely distributed in different geological
settings. Extensive studies have concerned mantle melting processes that generated these …

Large-scale Mesozoic volcanisms in the Great **ng'an Mountains (GXM), northeastern (NE)
China, are being extensively interested recently. However, the petrogenesis and …

The metavolcanic rocks of the Paleo-Mesoarchean Older Metamorphic Group (OMG) from
Jagannathpur area of the Singhbhum Craton occur as enclaves within the Singhbhum …

Crustal delamination induced by eclogitization of orogenic roots, in addition to plate
subduction, is an important process that transfers crustal materials back into the mantle …

A-type magmatism is an effective lithoprobe for constraining the tectonic evolution of
orogenic belts. In this study, we have identified two episodes of Late Paleozoic A-type …

The widespread late Carboniferous calc-alkaline and shoshonitic magmatic rocks in the
Awulale mountain provide crucial constraints on the tectonic evolution of the western …

Alkaline rocks crop out in subduction‐related volcanic arcs globally, whose genesis is
explained by partial melting of hybrid diapiric mélanges in the mantle wedge. Such a new …
