Alkalic Rocks and Carbonatites

1972
Alkalic rocks and carbonatites are among the rarest igneous rock-types. They tend to occur in stable platform areas and in Precambrian shields, rather than in orogenic belts. Barker (1969) estimated that in North America, alkalic rocks occupy a total surface area of only about 1500 square miles, and Heinrich (1966) concluded that the worldwide areal ...

Preserving carbonatite lavas

Geological Curator, 2014
Geological material is the most chemically diverse of all types of natural history collections. Each mineral assemblage will require a specific set of environmental parameters to ensure stability. Unfortunately these are not yet fully understood and it is widely recognised that there is no environmental condition which will be suitable for all.

Carbonatite-Alkaline Magma Immiscibility Conducing to Carbonatite REE Enrichment

2018
Carbonatite is a particular type of magmatic rocks enriched in REE relative to the majority of igneous rocks. Among the numerous carbonatites referenced worldwide, only a few of them contain economic REE concentrations widely considered as resulting from late- to post- magmatic processes.
