This paper provides a comprehensive review of the sinter deposits, formed largely of opal-A,
that are form around hot springs and geysers throughout the world. The discharge aprons …

Opaline silica (opal‐A) has formed in marine, lacustrine and geothermal environments
throughout geological time. During diagenesis opal‐A normally changes to opal‐CT, then …

The aim of the present study is to test diatomite rocks as alternative pozzolanic materials that
could be used for the manufacturing of pozzolanic cements in Greece. The diatomite rocks …

The separation of rare earth elements using diatomite M45 from aqueous solutions was
studied. The experimental isotherms for the adsorption of trivalent lanthanum, cerium, and …

Key Points Multiscale P wave velocities are acquired at seismic, sonic, and ultrasonic
frequencies from the field to the lab at a single study site P wave velocity decreases from …

A-ct-Borate minerals, such as colemanite, ulexite and borax, have been reported in Tertiary
continental basins of West Anatolia, Turkey, and Samos Island, Greece. Tuffaceous rocks …

Irregular masses, veins and leaf replacements composed of the phosphate minerals
vivianite, mitridatite, anapaite and hydroxylapatite occur in the Sarantaporo–Elassona Upper …

The Güzelöz-İncesu Plateaus are situated in the central and eastern parts of the
Cappadocian volcanic province (central Anatolia). This province contains many ignimbrite …

Earths were medicinal clays reported by authors of classical antiquity. Today, there are no
archaeological samples thereof, at least with irrefutable proof that they were used as …

For the subsurface characterization of carbonates, linking physical properties (eg porosity
and seismic reflectors) with their geological significance (eg sedimentary facies and …
