Sediment composition and U–Pb ages of detrital zircons in the Salina Cruz and Puerto Ángel beaches along the Gulf of Tehuantepec, Mexican Pacific

Geological Journal, Volume 59, Issue 10, Page 2897-2917, October 2024.
Sediment provenance in the Pacific Coast of Mexico The Salina Cruz and Puerto Ángel beach areas in the Gulf of Tehuantepec, Mexican Pacific coast represent an important economic sector of the region. In this study, the mineralogy and geochemistry of bulk sediments, and geochronology of 400 detrital zircons recovered from the beach sediments were ...

Comparative Study of the Kimberlites of Bakwanga (North Group) and Bakwa-Kalonji (South Group) In East Kasai, Democratic Republic of Congo.

Analecta
The presence of kimberlites in the Democratic Republic of Congo has been known since buttgenbach reported a typical ‘yellow ground’ in Katanga as early as 1908, and prospecting work before and after 1914 had already identified twenty-four pipes in ...

Ultrapotassic volcanic centres as potential paleogeographic indicators: The Mediterranean Tortonian ‘salinity crisis’, southern Spain

Geologica Acta, 2013
Dated peperites associated with ultrapotassic volcanic centres of the Neogene Volcanic Province of southeast Spain are of particular interest within the complex tectonomagmatic context of the Western Mediterranean because they show clear volcano ...

Genetic geological model of diamond-bearing fluid magmatic system

Записки Горного института
The article proposes a genetic geological model of diamond deposit formation associated with kimberlites and lamproites. It is based on the synthesis of published data on diamond-bearing kimberlite systems and an original study of the ontogenetic ...
