In district north of Teplitz, Archaean rocks of the Erzgebirge are cut by quartz- 

 porphyry, granite porphyry, and albite-granite intruded along fault lines. Tin 

 closely connected with granite, which is youngest, but there are broad zones of 

 impregnation around the granite, and these are the most important. Believes in 

 pneumatolytic deposition. Seams contain chiefly quartz and lithia-mica with 

 which are tinstone, wolframite and fluorspar, topaz being rarer. Chlorine shown 

 to occur in the micas of Zinnwald, Graupen and Altenberg. Thinks chlorine played 

 important part in the formation of the deposits. Stanniferous lodes near the 

 " impregnation zones " contain galena, arsenical and copper pyrites and malachite. 

 Tin lodes of Graupen district said to pass gradually southeastwardly into pyrite- 

 veins. Believes blende-bearing lead ores to be also in causal connection with 

 granitic intrusion, but that the conditions that originated them, acted further 

 away than those of the tin veins.
