Characterization of flowpath using geochemistry and(87)Sr/Sr-86 isotope ratios in the Yalahau Region, Yucatan Peninsula, Mexico

Jessica McKay Melissa Lenczewski ROSA MARIA LEAL BAUTISTA (2020)

The Yalahau region, located in the northeastern portion of the Yucatán Peninsula, hosts a series of elongated depressions trending north/south in the direction of Isla Holbox, identified as the Holbox Fracture Zone. Previous studies have explored the geomorphology and various hydrologic characteristics of the Yucatán Peninsula; however, there is a paucity of data concerning the interior region where the fractures are located. Strontium isotope ratios and major ion geochemistry data of the surface water and groundwater of this region serve as a hydrogeochemical fingerprint, aiding in constraining the hydrological boundaries, determining flow paths, and characterizing hydrogeochemical processes that impact the composition of the groundwater within the region. 87Sr/86Sr isotope ratios indicate a different signature than the surrounding bedrock Sr ratio, suggesting that the flow throughout the Yalahau region is moving through channels faster than that of much of the Yucatán. Through major ion geochemistry and 87Sr/86Sr isotope ratios, we were able to delineate at least two flow paths within the Yalahau region and identify a point of saline intrusion at least 35 km from the coast. Gaining an understanding of the hydrogeochemistry and water flow regions is crucial in determining the impact of various activities (e.g., extensive tourism, drinking water withdrawal, wastewater discharge/injection) that occur within the Yucatán Peninsula.

El presente estudio exhibe una revisión crítica de la relación trabajo-salario en la teoría económica. Versa acerca del discurso respecto a estas categorías en Adam Smith y Karl Marx quienes desarrollan las ideas seminales y fundamentales dentro de la Economía Política Clásica, Carl Menger y William Stanley Jevons quienes proporcionaron los fundamentos del trabajo como factor de la producción y como una mercancía igual a cualquier otra en la escuela económica neoclásica, y finalizando el análisis con un acercamiento desde la perspectiva de la Teoría de la Inexistencia del Mercado de Trabajo.

This research present a critical review of the labor-wage relationship in economic theory. Try on the subject defined by these two categories in Adam Smith and Karl Marx who developed seminal and fundamental ideas within Classical Political Economy, Carl Menger and William Stanley Jevons who provided the foundations to consider labor as a productive factor and as a commodity alike to any other, and ending the analysis with an approach from the perspective of the Theory of the Non-Existence of the Labor Market.
