Weathering and subsequent precipitation of Ca- and Mg-carbonates are the main processes
that control the CO 2 -concentration in the atmosphere. It seems logical, therefore, to use …

A full-scale plant for the recovery of struvite from calf manure has been installed at a calf
manure treatment facility at Putten (the Netherlands), and is in the final stages of testing. If …

Geochemical and hydrochemical studies were conducted in Nalgonda District (AP), to explore
the causes of high fluorine in waters, causing a widespread incidence of fluorosis in the …

A detailed structural study of Naxos (Attic-Cycladic massif, Greece) reveals two major
deformation events. The first one is associated with large scale thrusting and high-pressure-low-…

At Naxos, Greece, a migmatite dome is surrounded by schists and marbles of decreasing

Tin is inhomogeneously distributed on the continents, in relatively narrow, continent-sized
belts. On a reconstruction of the continents around the Atlantic Ocean before continental drift, …

In this paper a new and simple defluoridation method is presented using local Kenyan soil
derived from volcanic ash (eg Ando soils or soils with ‘andic’ properties) as a fluoride sorbent. …

Syngenite (K 2 Ca(SO 4 ) 2 ·H 2 O), formed during treatment of manure with sulphuric acid,
was studied by infrared, near-infrared (NIR) and Raman spectroscopy. C s site symmetry was …

A beach sediment from Ameland, the Netherlands was divided into 9 grain size fractions.
For each fraction the heavy minerals were separated subsequently and split in a number of …

The Dôme de l'Agout consists of an ellipsoidal mass of gneisses and migmatites emerging
from a large area of chlorite-sericite schists. Fluid inclusions in syn-metamorphic quartz …
