Cool Photo of the Week: Callaghanite Crystals
We noticed in last week’s AWESOME SCIENCE WORD contest that a number of you chose minerals, which often have beautiful crystals and are cut into what we commonly call “gems” or “jewels.”
This is a photograph of crystals of the mineral Callaghanite. It was named in honor of Dr. Eugene Callaghan, who was the Director of the New Mexico Bureau of Mines, in honor of his work studying magnesite deposits. This mineral contains magnesium and is typically found in an area with a magnesium deposit.
For those of you who are interested, the chemical formula for callaghanite is Cu2Mg2(CO3)(OH)6•2(H2O). Can you say that three times fast?
