About HurlbutiteHide

Dr. Cornelius S. Hurlbut, jr.
Greenish white, yellow or colourless
Crystal System:
Named in 1951 by Mary Emma Mrose in honor of Prof. Cornelius Searle Hurlbut, Jr. [June 30, 1906 Massachusetts, USA – September 1, 2005 Lexington, Massachusetts, USA], American mineralogist, professor of mineralogy at Harvard University, Cambridge, Massachusetts, USA.
Ca analogue of strontiohurlbutite. Has a paracelsian-type structure.

Compare minjiangite which is not a true (structural-chemical) but just chemical (Ba) analogue.
