Babingtonite


Babingtonite is a calcium iron silicate mineral, specifically a pyroxenoid. It has both divalent and trivalent iron, and the resulting electron transfer renders this species black and opaque. Levy (1824) named the mineral in honor of Dr. William Babington (1756-1833), Irish physician and mineralogist.

On this specimen, babingtonite forms triclinic crystals to 13 by 12 mm in calcite. They have a vitreous luster, which is good for the species. In describing babingtonite from this occurrence, Palache (1936) remarks about the high quality of the specimens. Here calcite has been removed with acid to reveal the babingtonite. An American classic, as seen at Harvard.
