The not-so-humble SiO₂     by Niels Dahl

SiO₂ is one of the most common compounds in the crust of the Earth as non-descript quartz and in silicates. Under special conditions it can, however, form spectacular specimens of quartz, opal and chalcedony, which can be of gemstone quality and very valuable. It also has historical value as it was extensively used amongst stone-age cultures as the material of choice for their tools.

Niels completed his Cand.Scient. (M.Sc. by thesis) at Copenhagen University many years ago, after which he emigrated to Australia and worked predominantly in gold exploration as staff geologist or contractor/consulting geologist for several companies, mostly in Western Australia and with a couple of overseas assignments. Niels is now retired and has given up all memberships of professional organisations.
