Editing Gabbro (section)

==Etymology==
The term "gabbro" was used in the 1760s to name a set of rock types that were found in the [[ophiolite]]s of the [[Apennine Mountains]] in Italy.<ref>Bortolotti, V. et al.

Then, in 1809, the German geologist [[Christian Leopold von Buch]] used the term more restrictively in his description of these Italian ophiolitic rocks.<ref>Bortolotti, V. et al.
