Comments on the geologic information

  • MANGANESE BEARING CLAY IN TWO STREAKS DIPPING STEEPLY TO SOUTHEAST AND SEPARATED BY BARREN CLAY. MOST OF NODULES OF PSILOMELANE, BUT SOME CONTAIN PYROLUSITE. SOME CLAY ESPECIALLY IN NORTHWEST STREAK IS MIXED WITH POWDERY PYROLUSITE. SOFT GRAPHITIC MATERIAL IS CLOSE TO JASPEROID MASSES: CLAY STREAKS ARE NEARLY PARALLEL STRIKE OF ERWIN FORMATION
