Controls for ore emplacement

  • Dikes

Comments on the geologic information

  • NARROW INCLINED DIKE ALONG NEW LONDON VEIN IS CUT BY 3-4 FT WIDE VERTICAL BASIC DIKE (N60E). SOUTHWARD (UPPER) PART OF INCLINED DIKE HAS BEEN FAULTED SEVERAL FT UPWARD ALONG VERTICAL DIKE RELATIVE TO LOWER PART. ORE BODY IS IN THE PART OF THE VERTICAL DIKE BETWEEN FAULTED PARTS OF THE INCLINED DIKE AND HAS SAME MINERAL COMPOSITION AS NARROW VEIN. ORE BODY IS CUT BY SEVERAL REVERSE FAULTS (ABOUT N75W, 55SW). EACH FAULT DISPLACES UPPER PART OF ORE BODY AS MUCH AS 10 FT TO THE NE.
