Though department of Lozere is rich in metalliferous veins, tin ore has not 

 hitherto been recorded there. Author discovered a vein close to Great Monastier 

 fault, in parish of Barjac. Country rock is mica schist, vein dips 60, and 

 is 7% feet thick at outcrop. The gangue consists chiefly of barytes and quartz; 

 between these is a thin band of cassiterite barely 1 inch thick with which are 

 closely associated pyrolusite and wolframite.
