Ontario, Canada, about thirty-five miles north of Georgian Bay, the town of Sudbury from which the district takes its name lying in Latitude 46° 30' West Longitude 81°. The Sudbury breccia zones would have been ductile during partial melting, whereas stockwork of footwall granophyre in granitic and gneissic units suggests that these rocks were able to deform in a brittle way if strain rates were sufficiently high and melt pressure temporarily exceeded lithostatic pressure (Péntek et al., ). Under ductile.
Details on Township names and locations within the study area can be found on Ontario Geological Survey Map (Sault Ste. Marie-Elliot Lake, , scale) and Map (Sudbury- Cobalt, , scale). The River Valley intrusion is located about road kilometres (~60 km direct) northeast of the City of Greater Sudbury, Ontario (Fig. Hanley JJ, Mungall JE () Chlorine enrichment and hydrous alteration of the Sudbury Breccia hosting footwall Cu-Ni-PGE mineralization at the Fraser mine, Sudbury, Ontario, Canada.

Sudbury Breccia (SB), also known as Frood breccia Yates,Zurbrigg,Levack breccia Mitchell and Mutch,Mitchell and Mutch,common Sudbury Breccia (Speers, ), Sudbury-type breccia and pseudotachylite (Thompson and Spray, ) consists, in general, of subrounded fragments set in a fine-grained to aphanitic matrix which may be Cited by: The Sudbury impact structure is geographically divided into the North Range, the South Range, and the East Range ().In the North and East Ranges, the SIC is in contact with the Archean Levack gneiss complex and Cartier Batholith of the Superior Province, whereas in the South Range, it is in contact with ca.

Volatiles released from samples of Sudbury breccia from sulfide-mineralized and sulfide-barren environments showed the following: (1) higher average abundances of light saturated hydrocarbons (C1–C4) and an approximately 2× higher total abundance of hydrocarbons (mol/g of rock basis) associated with samples from the mineralized study area.
samples were prepared for petrographic study. This includes 22 samples of Barotiya rocks, 16 Sewariya granite, 18 medium-grained Govindgarh granite, 11 coarse-grained Govindgarh granite, and 5 tourmaline from quartz-rich veins.

The area in the dashed box is shown in detail in Figure 1b. Rb Sr and Sm Nd measurements were undertaken on Footwall Breccia samples originating from Levack Township in the North Range of the Sudbury Structure. The granitic to quartzdioritic matrix of this heterolithic breccia, which contains shocked rock and mineral fragments, yields a Rb Sr isochron age of ± Ga (I Sr = ± ; 2σ errors), based on the.

The Wanapitei Complex (6 km× km), lying km southeast of the Grenville Front, consists of a northwestern zone of gabbro and folded injection breccia and a southeastern layer of intensely folded hornblendeplagioclase gneiss.
Disseminated Ni-Cu sulphides are unevenly distributed in a zone between the injection breccia and the folded gneiss.

Sc. A Petrographic Study of the Spragge Group.Sudbury breccia represents an important mineral exploration target as it hosts Sudbury's largest Ni–Cu–PGE deposit (Frood-Stobie), Cu–PGE and PGE-only ‘footwall deposits'.
Over million metric tons of Ni and million metric tons of Cu, along with Co, Ag, Au and PGE, have been mined from this exceptional mining district.The Miocene aged polymetallic (Ag-Zn-Sn-Pb) Pirquitas deposit of NW Argentina, hosted in an uplifted horst of Ordovician metaturbiditic rocks, defines the southern extent of the Andean Tin Belt.
The nearby and recently discovered Cortaderas breccia-hosted Ag-Zn deposit contrasts markedly with the main Pirquitas deposit. To address these differences, a comprehensive geological, mineralogical.
