Fluorescence of Limestones and Limestone Components

Applied Spectroscopy, 1997
The fluorescence of a series of limestones has been investigated; the relative fluorescence intensities of these limestones differ by a factor of 10. With UV excitation, the fluorescence spectra of these limestones exhibit two distinct peaks, one blue and one red; the relative magnitude of the blue peak is larger for more fluorescent limestone.

Kinetics of sulphation of limestone and precalcined limestone

Chemical Engineering and Processing: Process Intensification, 1991
Abstract The kinetics of sulphation of large (2–4 mm) limestone and precalcined limestone particles were investigated at temperatures below the decomposition temperature of CaCO3. In both cases it was found that, over a wide range of conditions, the sulphation rate decays with t− 1 2 , indicating that diffusion of SO2 through the product CaSO4 ...

Black limestone used in antiquity: recognizing the limestone of Teos

Archaeometry, 2018
This paper documents the petrographic and isotopic characteristics of some black limestones that were exploited in antiquity near the ancient site of Teos in Ionia (south‐western Anatolia, Turkey). The best‐quality black limestone of Teos is represented by a series of step‐cut‐shaped blocks situated north of the Seferihisar–Sığacık road, destined to be
