A geologic problem has been addressed in the Fraser-Strathcona Deep Copper mine, Sudbury, wherein diabase dikes and the chalcopyrite vein system have a mutually crosscutting relationship. In any situation where crosscutting relationships are mutual t

La mine Thayer Lindsley, situee sur le flanc sud du complexe igne de Sudbury (1.85 Ga), fournit un exemple d'une mineralisation en sulfures de Ni-Cu-EGP pres du contact et en sulfures de Cu-Ni-EGP dans la paroi inferieure (EGP: elements du groupe du

The Thayer Lindsley mine is located in the South Range of the Sudbury impact structure, near the contact between the 1.85 Ga Sudbury Igneous Complex (SIC) and the Paleoproterozoic Southern Province. NiCu ore zones at the mine are strongly deformed

The Needle Falls Shear Zone is a major Paleoproterozoic discontinuity separating an Archean craton from accreted Paleoproterozoic terranes in the western Trans-Hudson Orogen. It is a 1 km-wide subvertical mylonite zone forming the southwestern sector

The Sudbury Structure, formed by meteorite impact at 1850 Ma, consists of three major components: (1) the Sudbury Basin; (2) the Sudbury Igneous Complex, which surrounds the basin as an elliptical collar; and (3) breccia bodies in the footwall known

A new method of producing glass beads from whole-rock powders has been tested for use in laser sampling-inductively coupled plasma-mass spectrometry (LS-ICP-MS). Glass beads are produced in a tungsten strip heater cell, under an Ar atmosphere of 275

The late-kinematic structural architecture of the Flin Flon domain is dominated by a network of anastomosing shear zones formed by compressional deformation during the Proterozoic Trans-Hudson orogeny (ca. 1900-1800 Ma). A number of structurally cont
