Controls for ore emplacement

  • Sims And Day (1992) Note That The Fundamental Regional Control On Gold Deposits In The Superior Province Is Transcurrent And Oblique Slip-Shear Deformation Zones That Formed In Late Archean Time.

Comments on the geologic information

  • AT THIS SITE, THERE IS A LARGE PERSISTENT QUARTZ VEIN THAT IS PROBABLY OF HYPOTHERMAL ORIGIN. THE VEIN ACCOMPANIES A GRANITE DIKE, BUT IS MINERALIZED ONLY LOCALLY WITH CU, PB, AND ZN SULPHIDES. THE OUTCROP IS STAINED AT THOSE SITES AND ASSAYS SHOW VARIABLE AMOUNTS OF GOLD.

Economic information about the deposit and operations

Commodity type Metallic
Deposit size Small
Significant No

Comments on development

  • EXPLORATION FOR GOLD DEPOSITS IN THE REGION HAS BEEN HAMPERED BY A GENERALLY THIN, DISCONTINUOUS MANTLE OF PLEISTOCENE GLACIAL DEPOSITS. ; ECON.COM: THE OCCURRENCE OF LARGE GOLD DEPOSITS IN CANADA SUGGESTS THAT THE GREENSTONE-GRANITE TERRANES OF MINNESOTA ARE FAVORABLE FOR THE OCCURRENCE OF IMPORTANT GOLD DEPOSITS.
