The mineral’s chemical formula is (Ti4+,Sc,Al,Mg,Zr,Ca)1.8O3. The elements found in it are titanium, scandium, aluminium, magnesium, zirconium, calcium, and oxygen. Samples from the meteorite include some which are zirconium rich. The mineral was found in conjunction with the already identified mineral davisite, within an olivine aggregate.
Origin and properties 
Panguite is in a class of refractory minerals that formed under the high temperatures and extremely varied pressures present in the early solar system, up to 4.5 billion years ago. This makes panguite one of the oldest minerals in the solar system. Zirconium is a key element in determining conditions prior to and during the solar system’s formation.
Chi Ma, director of the Geological and Planetary Sciences division’s Analytical Facility at the California Institute of Technology was the lead author of its first peer-reviewed article, published in American Mineralogist. Ma has been leading a nano mineralogy investigation, since 2007, of primitive meteorites, including the well studied Allende meteorite. The mineral was first described in a paper submitted to the 42nd annual Lunar and Planetary Science Conference in 2011.
