Mineralogical and Geotechnical Properties of Clay Minerals in Northern Borno, Nigeria

Clay Minerals: Adsorbophysical Properties

The structure and features of surfaces of clay minerals (kaolin, montmorillonite, etc) have an important scientific and practical value. On the surface the interrelation of processes at electronic, atomic and molecular levels is realized. Availability of mineral surface to external influences opens wide scientific and technical opportunities of use of the surface phenomena, so the research of c...

Clay Minerals and Catalysis

More than half a century ago, Irish physicist John Desmond Bernal and Swiss geochemist Victor M. Goldschmidt independently proposed that clay minerals may have played an important role in prebiotic synthesis (Bernal 1949; Goldschmidt 1952). I concur that mineral catalysis must have had a central role in prebiotic synthesis because most uncatalyzed reactions start from simple precursors like hyd...

Estimating of geotechnical properties of clay soil with dynamic cone penetration (DCP) test

Dynamic cone penetration (DCP) test is used more in pavement design and construction, and less for subsurface geotechnical investigation and clay core dam. In the present article, evaluating geotechnical parameters of Sanandaj’s clay in the western region of Iran using the DCP test was taken into account. Accordingly, 6 trial pits with maximum depths of 15 m were excavated manually in various s...
