The classical crystal Goniometry was blank in Chinese mineralogy before 1949. The teaching of this course began mainly in the Peking College of Geology (now China University of Geosciences) after it’s establishment in 1952. Professor Peng Z. measured successfully in 1958, the first new mineral discovered by Chinese mineralogist, Hsianghualite. It is very complex in form, and recognized to be the representative spices of isometric tetartoidal class (T=23), 3L24L3, instead of cobaltite in literatures.
Thereafter, a laboratory of crystal growth and morphology equipped mainly with STOE two circle optical goniometer and NIKON microscopes, had been established in CUG 1986, open to class teaching and research. Now more than 30 of Chinese mineral crystals have been studied both by V. Goldschmidt method and recent surface microtopography of P. Tolansky method, under the work of professor Wang group. On three nearly perfect crystals occurred in Dachang Sn deposit, they draw the complete form of jamesonite, which was questionable from 1923 reviewed by V. Goldschmidt. They also published the form variation series during the evolutionary system of China idex mineral such as dimond, wolframite, aegirine, arfvedsonite, cassiderite, stibnite. At the same time, a lot of Chinese mineral such as realgar, orpiment, garnet, visuvianite, zeolites, bournonite, bertrandite firstly measured. All of these work strongly enhanced the function of museum and the foundation of Chinese mineralogy.
Now the scientific group work on the mineral material and gem minerals as beryl, corundum so as to promote the sustainable development of classical goniomtry both for class teaching and public application.
