SUMMARY
The purpose of this article is to throw light on the general outlines of the problem cOlll'Ceming" the Lower Silesian magnesite depOSits related to serpen-tinite massifs. The results obtained during the
15--year period of research works conducted on this problem allowed the author to present the general geological occurrence conditions of magnesites, and the character of the zones mineralized with magne-site. Moreover. the data on the present-day mineral raw material basis are given, as well as the degree of its use, the economical importance, and the prospects are discussed.
