Description
Luminescent calcite formations (N = 21) were taken from nine karst caves in a valley in Northeast Iowa. Ten samples fluoresced bright blue under UV light and phosphoresced green. Four samples fluoresced dull pink instead of blue. Seven samples do not fluoresce as strongly as the other samples. An elemental analysis was performed on the samples using a Bruker Tracer 5g handheld XRF. Analysis shows some samples may experience fluorescence quenching by the presence of iron and some amount of fluorescence by manganese.
