“Various potassium silicates -- leucite, feldspar, sericite, and glauconite -- and the potassium sulphate, alunite, have received attention and certain of them have been utilized to a small extent, but none of them are normally able to compete on the market.”
“The gold, in particles hardly visible to the eye, is in a sandy matrix and is associated with chloritoid, sericite, calcite, graphite, and other minerals.”
“The wall rocks have undergone a "propylitic" alteration, with development of chlorite, epidote, and probably sericite, much as at Butte.”
“Where sericite is dominant, the alteration is called sericitic alteration.”
“Alunite is a potassium-aluminum sulphate, which differs from sericite in that sulphur takes the place of silicon.”
“A dark red, finely laminated rock consisting chiefly of decomposed biotite and feldspar, occasional quartz grains and sericite and much iron oxide.”
