Study on Genesis of Skarns and the Related Minerals

The present study is concerned with the so-called skarns designated after the rule applied to generally and the related minerals comprised in several ore deposits distributing in the Chūgoku District with respect to their geneses and in pursuit of so-called pyrometasomatic or contact effects. Inspection of the paragenetic relationships among, and identification of, the respective minerals have been fulfilled as elaborately as possible by means of an ordinary microscope and x-ray diffractometer in conjunction with heat treatments especially for some specimens, resulting in more precise interpretation other than various concepts given previously by many authors and furthermore in discovery of some rare minerals taking an important part in the subject under consideration.
