SUMMARY

Small vein intrusions found to occur in serpen-tinites of the Gogo16w-Jordan6w massif, Lower Sile-sia, . are described. Dykes of strongly hydroUzed microgabbro, lamprophyres of the groups of camp-. tospessartite and vogesite, grey and white aplites, as

well as gabbroic and granitic pegmatites are dis-tingUished, and their character and occurrence con-' ditions are given. The vein ilntrusions reveal contact selvage of reaction rim type, with well developed hydrobiotite, vermicuUte, talcous arid 'Chlorite zones. The chemical compositions of the vein intrusions are presented in the projection according to S.R.N. . Nocholds and R. Allen. Distinguished are two

mag-matic differentiatian series, one with the main gabbro intrusion of Sob6tka, another with the Sob6tka gra-nite, two series of differentiation of fractional gabbroic and granite macma.

The differentiation of rocks in small vein intru-sions has been explained by assimilation of ultrabasic rocks, according to the differentiation of serpentinite massifs, as regards magnesium and calcium 'Contents. Hydrothermal magnesite mineralization related to post-magmatic activity of granite intrusion has been characterized genetically, as well.
