THE INTRUSIONS IN THE GRANITE OF PARYS. 

 ORANGE FREE STATE. 



By Prof. Samtkl Ja.mks Shand. Ph.D., D.Sc. F.G.S. 



[Abstract.] 



The granite of Parys is intersected by a network of apjxir- 

 ently intrusive veins of a dense black rock, having the appear- 

 ance of tachylyte. Close study in the field and in the laboratory 

 shows that in some respects this material differs from a normal 

 igneous glass, and it is thought that it represents a " melt " of 

 granite, produced by mechanically developed heat. The question 

 was discussed fully, and the nature of the intrusions was illus- 

 trated by photographs and drawings. 



A second tvpe of intrusion in the same district is shown bv 

 a great dyke, nearly 600 yards in width, of a granophyric quartz- 

 dolerite. 



A full account of the phenomena has been communicated to 

 the Geological Society of London.
