Editing Baddeleyite (section)

==Origin of the name==
It was named for Joseph Baddeley. The mineral was discovered in [[Rakwana]], [[Sri Lanka|Ceylon]] (now [[Sri Lanka]]). Baddeley was a superintendent of a railroad project in Rakwana. As recounted by J.J.H. Teall – director of the British Geological Survey in the early 1900s – baddeleyite was discovered consequent to the discovery of [[geikielite]].

Baddeley sent specimens of several pebbles from the [[Rakwana]] railroad excavations to the [[Geological Museum|Museum of Practical Geology in London]], where a Mr.&nbsp;Pringle examined them and attempted to classify them.
Pringle was unable to assign the specimens to a known mineral species and submitted them to Teall. After analyzing the specimens, Teall concluded that the mineral was mainly composed of [[titanic acid]] and [[Magnesium oxide|magnesia]], with an incidental mixture of [[iron(II) oxide|protoxide of iron]]. Geikielite has the composition of {{chem2|MgTiO3}}.
Teall and Pringle decided to name the new mineral ''geikielite'', naming it after Sir&nbsp;[[Archibald Geikie]], then the Director General of the Geological Survey.

Baddeley sent more specimens to Teall, in order to provide an exemplary specimen for display at the Museum of Practical Geology. While trying to find the specimens, Teall noticed that one of them was different from the rest: This new mineral was black in color, with a submetallic lustre, and a [[Mohs hardness|hardness]] of 6.5&nbsp;. After analyzing it, the odd mineral was determined to not be {{chem2|MgTiO3}} (geikielite), but instead {{chem2|ZrO2}}. Teall proposed mineral name ''baddeleyite'', after Joseph Baddeley, to honor the man who brought the two new minerals to notice.<ref name="Fletcher"/>
