Importance of carbonatite for economic mineral deposits
Answers
Answer:
carbonatite are very largely converted to oxides during ignition which also converts acid insoluble silicate minerals to acid soluble calcium silicate
Explanation:
The igneous apatite deposits which are of considerable importance in the fertiliser industry, are associated with three inter-related types of intrusive rocks, namely, carbonatites, nepheline syenites and alkaline ultrabasic rocks. The economic significance of the four carbonatite alkalic complexes is indicated, and the feasibility of utilising the Amba Dongar carbonatite complex for multipurpose chemical industry is discussed. Attention is drawn to the genetic relation of carbonatite alkalic complexes to the alkaline and ultrabasic rocks. In the context of Amba Dongar carbonatite, the differentiation trends in the tholeiitic basalts (involving the earlier separation of pyroxenes), and the relation of the carbonatites, nephelinites and phonolites are delineated with the help of differentiation diagrams and chemical data.
