Physical degradation and early diagenesis in foraminiferal tests after subaerial exposure in terrigenous-depleted beaches of Yucatan, Mexico
Autor: John S. Armstrong-Altrin, Elsa Arellano-Torres, Juan José Kasper-Zubillaga
Publikováno v: Carbonates and Evaporites. 34:1175-1189
Degradation, diagenesis, and mineralogical changes in foraminiferal tests are recognized as mechanisms that control their preservation and destruction under the subaquatic/aerial conditions, commonly influenced by processes such as dissolution, abras

We study shifts in phytoplankton proxies linked to terrigenous inputs and teleconnections in a core from Soledad Basin, Gulf of Ulloa, NW Mexico, spanning the end of the deglaciation and the Holocene. We used biogenic opal (% opal), organic carbon (%

Mineralogical and geochemical implications of weathering rates in coastal dunes and beach sands close to a volcanic rock source in the western Gulf of Mexico, Mexico
Autor: Elsa Arellano-Torres, Juan José Kasper-Zubillaga, R.O. Mejía-Ledezma, M. Mendieta-Lora, L.F. Álvarez Sánchez
Publikováno v: Geochemistry. 78:323-339
Coastal dune (CD) and beach sand samples were mineralogically and chemically studied to assess the weathering rates in a coastal area surrounded by the Trans-Mexican Volcanic Belt (TMVB). The study area is a narrow coastal plain with sub-humid warm w

Mineralogy and geochemistry of Tecolutla and Coatzacoalcos beach sediments, SW Gulf of Mexico
Autor: Bárbara Yaneth Pérez-Alvarado, Armel Zacharie Ekoa Bessa, Jayagopal Madhavaraju, Fabiola Vega-Bautista, John S. Armstrong-Altrin, Mayla A. Ramos-Vázquez, Juan José Kasper-Zubillaga
Publikováno v: Applied Geochemistry. 134:105103
Mineralogic and geochemical studies were performed in the Tecolutla and Coatzacoalcos beach sediments, located at the SW Gulf of Mexico. The main concern of this article is to infer the weathering, provenance, and degree in which trace metal pollutio
