Abstract
El presente artículo resume la caracterización químicas, mineralógicas y estructural de dos phasas (arcillas tipo montmorillonita) ampliamente utilizadas en el campo de la medicina tradicional en la región altiplanica de Bolivia, una de la localidad de Andamarka (Departamento de Oruro) y otra de Achocalla (Departamento de La Paz), Bolivia. Las dos presentan como fase de interés la arcilla tipo montmorillonita, siendo la de La Paz con un mayor contenido de impurezas fundamentalmente tipo feldespáticos, en la otra se presenta fundamentalmente como impureza pero minoritaria sílice tipo cuarzo. El mayor carácter Sódico - Potásica de la arcilla de La Paz, frente al carácter Cálsico del de Oruro, favorece en gran medida su capacidad como adsorvente de glicol o agua, de hidratación e hinchamiento, o neutralizante de un medio acido. Por lo que la Arcilla de la localidad de Achocalla presenta mejores características para su aplicación tradicional.
The present article summarizes the chemistry, mineralogical and structural characterization of two "phasas" (clays montmorillonite type) strongly utility in traditional medicine in the "Altiplano" region of Bolivia, one from to Achocalla locality (La Paz) and other Andamarka (Oruro), Bolivia. Both present how phases of interest the clay montmorillonite, but the La Paz clay have more impurity (pheldespate phases), in the other the minor phase impurity is the silice quartz type. The more Sodic - Potasic character of La Paz clay, in front of the calcic character of Oruro clay, this favoured the glycol and water adsorption, hydration end acid neutralization properties in the La Paz clay. In this sense this clay has better properties to your application in traditional medicine.
