Controls for ore emplacement

  • Near Syenite Contact

Comments on the geologic information

  • INTRUSIVE ROCKS COULD UNDERLIE THE SITE AT SHALLOW DEPTHS, AND PROVIDE A CONTACT METAMORPHIC ENVIRONMENT AT THEIR CONTACT WITH THE OVERLYING ARGILLITE AND QUARTZITE. THUS, ADDITIONAL MINERALIZATION COULD OCCUR AT DEEPER DEPTHS. ; GEOL.DESC: SYENITE NEARBY
