Agromineral resources are minerals and rocks used to improve soil productivity and health. These resources can be applied: indirectly, by extracting and concentrating one or more …
For over 50 years, Mesozoic tholeiites, kimberlites and carbonatites from the South American platform have been enabled the understanding of melting processes in the Earth's …
Дан сравнительный анализ геологии и минерагении карбонатитов и кимберлитов- главных производных мантийных щелочно-ультраосновных магм. В первой части …
The kimberlites, kamafugites and phlogopite-picrites of Alto Paranaíba Igneous Province (APIP), southern Brazil, span a range between~ 91 and 78 Ma with new in-situ, more tightly …

We discuss the overall characteristics of a recently recognized kamafugite province in West Qinling, China, using field observations and geochemical data. We discuss the petrogenesis …
The carbonatite-related Nb deposits of the Alto Paranaíba Igneous Province (APIP) in central Brazil, currently account for∼ 92% of the global Nb production. In the APIP …
Here we present new data on the major and trace element compositions of silicate and oxide minerals from mantle xenoliths brought to the surface by the Carolina kimberlite …
Kimberlitic, kamafugitic and alkaline-carbonatitic (KKAC) rocks have been proposed to be directly related to supercontinent cycles. However, the hybrid nature of KKAC magmas …
Alkaline‑carbonatite complexes from the Alto Parnaíba Igneous Province (APIP) host important supergene concentrations of Nb, REE, P, and Ti. To quantify water/rock interaction …
