| conc_proc: | Zone Of Structual Disturbance In Schists, Opened Up A Limited Zone, Or A Steeply Inclined Chimney Which Provided Favorable Conditions For Circulation Of Hydrothermal Solutions Which Caused Rock Alteration And Replacement By Sulfides. |
| ore_ctrl: | Zone Of Structual Disturbance Found Where East Dipping Foliation Lies Adjacent To West Dipping Foilation. This Zone Extents Through Newton Mine. Due To Lack Of Lithologic Correlation Across Strike, This Zone Is More Suggestive Of Fault Along The Axial Plane Of An Isoclinal Fold, Than A Zone Of Stretching And Displacement In An Over - Turned Limb Of A Major Anticline. |
