PROCEEDINGS 



or THE 



GEOLOGICAL SOCIETY OF LONDON, 



SESSION 1898-99. 



November 9tli, 1898. 

 W. Whitakek, B.A., E.E.S., President, in the Chair. 



Eichard Taylor Manson, Esq., Derneholm, Stanhope Koad, 

 Darlington, was elected a Fellow of the Society. 



The List of Donations to the Library was read. 



The Pkesident invited the attention of the Eellows to the new 

 Geological Survey Index Map of England and Wales, which had 

 been hung upon the walls of the meeting-room during the recess. 



Mr. Batjerman, in exhibiting a map of the Gellivaara iron-ore 

 deposits, pointed out that these constitute a chain some 5 miles 

 in length, and are made up essentially of magnetite interlaminated 

 with apatite. In addition to these mines, which are far north 

 of the Arctic Circle (70 miles north and 120 miles west of the Gulf 

 of Bothnia), he had had an opportunity of visiting the deposits of 

 Kiirunavaara, 100 miles still farther north ; here the rocks are of 

 a slaty character, and the magnetite is included in felsite-porphyry. 

 The Gellivaara ores are contemporaneous with the surrounding rock, 

 while the Kiirunavaara ores appear to have been introduced at a 

 later period. Mr. Bauerman exhibited specimens from both 

 districts, and drew attention to the phenomena of polishing by 

 wind-action, etc. 



The following communications were read : —
