Published in 2017 at "Mineralogical Magazine"

DOI: 10.1180/minmag.2016.080.152

Abstract: Abstract This study presents the first crystal-structure determination of natural MgCO3·5H2O, mineral lansfordite, in comparison with previous structural works performed on synthetic analogues. A new prototype singlecrystal X-ray diffractometer allowed us to measure an extremely… read more here.
