Abstract

El vanadio (V) y el uranio (U) son elementos críticos para la industria energética y tecnológica. Se caracterizan por su baja abundancia en las rocas de la corteza terrestre, pero pueden ser concentrados y dar origen a depósitos minerales sedimentarios como resultado de procesos de redox durante la sedimentación y la diagénesis. Las anomalías de V-U en La Sota, Ecuador, se encuentran en calizas negras y lutitas calcáreas negras del Cretácico. En este trabajo se presentan los resultados de un estudio geoquímico y un análisis multivariante, que permite inferir cuatro asociaciones: 1) materia orgánica diseminada en las calizas que contiene V y Zn, probablemente en forma de complejos organometálicos; 2) minerales fosfatados y concentraciones de U, HREE y Ni, posiblemente incorporados como elementos traza en los fosfatos, compatibles con sedimentación en un ambiente anóxico; 3) Ca contenido en carbonatos de ambientes marinos; y, 4) elementos litófilos asociados a la presencia de minerales detríticos, como cuarzo, plagioclasa, feldespato, micas, arcillas y oxihidróxidos de Fe-Mn-Ti, producidos por meteorización y erosión. Los resultados sugieren que el V está asociado principalmente con la materia orgánica de origen marino diseminada en las calizas bituminosas, mientras que el U está vinculado con el P, lo que indica la formación de fosfatos uraníferos durante la sedimentación.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-08:

  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 8 (PlumX).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
  • Additionally, the work has been submitted to a journal classified as Diamond in relation to this type of editorial policy.
