Monoclinic Minerals blue = crystallographic axes red = indicatrix axes The angles of the other two indicatrix axes are described relative to the closest crystallographic axis e.g. Z ^ c = +15° (it’s positive if the indicatrix axis falls within the obtuse angle between a and c axes) and X ^ a = -5 ° (it’s negative ... Nettetdrawings he made for his articles, the Tissot indicatrix is represented. Te-ichmuller mentions the name Tissot in a historical section in one of his fun-damental papers in which he points out that quasiconformal mappings were initially used by geographers. The name Tissot is missing from all the known historical reports on quasi-conformal mappings.
