MINED TRONA THAT IS USED FOR SODA ASH PRODUCTION IS COARSE, CRYSTALLINE MATERIAL FROM A MASSIVE TRONA BED. THIN SEAMS, LIKE THIS SPECIMEN, WERE ENCOUNTERED IN SHAFT SINKING AND THEREFORE SPECIMENS OF THIS TYPE OF CRYSTALLINE TRONA ARE NOT AS REDILY AVAILABLE AS THE MASSIVE, COARSE CRYSTALLINE TRONA.
