BROAD DISTRIBUTION OF CRYSTAL-FIELD ENVIRONMENTS FOR ND3+ IN CALCITE

Withers S.H.; Peale R.E.; Schulte A.F.; Braunstein G.; Beck K.M.; Hess W.P.; Reeder R.J. (2003)

Calcite micro-crystals were grown from solution with single crystal dimensions up to 3 mm and doped up to ~0.1% with Nd3+ ions. Phase purity was verified by powder x-ray diffraction. The concentration of Nd3+ was measured ...
DIFFERENCES IN GRAIN GROWTH OF CALCITE: A FIELD-BASED MODELING APPROACH

Herwegh M.; Berger A. (2003)

Normal grain growth of calcite was investigated by combining grain size analysis of calcite across the contact aureole of the Adamello pluton, and grain growth modeling based on a thermal model of the surroundings of the ...
MICROSCOPIC AND SPECTROSCOPIC INVESTIGATION OF THE CALCITE SURFACE INTERACTED WITH HG(II) IN AQUEOUS SOLUTIONS

Godelitsas A.; Astilleros J.M.; Löns J.; Putnis A.; Hallam K.R. (2003)

The interaction of the {101¯4} cleavage surface of calcite with Hg(CH3COO)2 aqueous solutions with concentration of 5 mM Hg(II) (pH 3.5), was investigated using microscopic and spectroscopic techniques. In situ atomic force ...
STRAIN INVESTIGATIONS ON CALCITE MARBLES USING NEUTRON TIME-OF-FLIGHT DIFFRACTION

Scheffzük C.; Siegesmund S.; Koch A. (2004)

In order to describe and explain the effect of bowing of marble facade panels, neutron time-of-flight diffraction was applied to determine residual macro- and microstrain on the calcite mineral phase. The measurements were ...
