Economic geology is a mixtum compositum of all geoscientific disciplines focused on one
goal, finding new mineral depsosits and enhancing their exploitation. The keystones of this …

This paper reviews the most relevant uses and applications of zeolites in anaerobic
digestion processes. The feasibility of using natural zeolites as support media for the …

Extensive mining, massive urban waste landfills, nuclear accidents and urban runoff
discharge huge volume of special wastewater streams to the water bodies. Appropriate …

Bentonites are clay rocks consisting predominantly of smectite. They form mainly from
alteration of pyroclastic and/or volcaniclastic rocks. Extensive deposits, linked to large …

In the last few years, several ground-based and airborne field campaigns have allowed the
exploration of the properties and impacts of mineral dust in western Africa, one of the major …

The influence of layer charge and charge distribution of dioctahedral smectites on the
rheological and swelling properties of bentonites is examined. Layer charge and charge …

Layer charge is an important property of 2: 1 phyllosilicates originating from isomorphic
substitutions in the structure, from vacancies in the octahedral sheet and from unsatisfied …

The Westerwald region is one of the major ceramic clay mining areas of Germany. The
mined clays were deposited on the weathered Rhenish massif during Eocene and …

Zeolites are the main mineral components in altered volcaniclastic rocks ranging in age and
composition. They form by alteration mainly of volcanic glass in various geological …

A review and a synthesis of the geological, mineralogical, and crystal chemical data
available in the literature on active Spanish bentonitic exploitations were done, and at the …
