Caracterización geológica, propiedades físicas mecánicas, calcinación y filtración de las diatomitas del sector de Angostura, pueblo de Villingota (Santa Elena – Ecuador).

Abstract

The characterization of the diatomite of the Angostura village of Villingota in the province of Santa Elena was carried out by the study of its properties and physical, chemical and mineralogical characteristics using analysis techniques such as X-ray fluorescence, X-ray diffractometry and tests Such as the pycnometer or the hydrostatic balance. Observing the established standards for these rocks, it was determined that the chemical composition has a low silica content (45.95%), and high values of iron oxides (8.64%) and aluminum (12.58%). The mineralogical phases determined on average are quartz (10.37%), calcite (30.02%), oligoclases (13.34%) and the group of clays "Montmorillonite - Ilite" (17.66); The microscopic analysis showed that the samples contain, in addition to diatoms, fossils of silica spicules of sponges; The spatial distribution of them is not regular and not in large quantities, thus determining that the diatomites studied belong to a material of poor quality. probable reserves of 6,820.62 Tons
