Massive, with a structure varying from coarse crystalline to trouoreu— 

 line crystalline-granular in A.— to fine crystalline-granular, almost ;'o' n \;' ' 

 compact, in B. The gangue in these specimens consisted almost 

 entirely of quartz and calcite ; sample A. containing in addition 

 here and there a little iron-pyrites.
