Geometric Microscape of Agate
by Bernardo Cesare, Department of Geosciences, University of Padova, Padova, Italy
"Crazy Lace" is an agate collected in Mexico, which offers great opportunities for aesthetic photomicrography.
Here we see the common arrangement of fibers of chalcedony (microcrystalline quartz) in parallel bands alternating with black thin layers of Fe oxides.
Polarized light photomicrograph, crossed polarizers and red tint plate. width 5.4 mm.
Sample kindly provided by Denise M. Harrison.
