Till Ontario 1984

Multi-year till (surface and from sonic drill core) sampling survey, Black River-Matheson, Ontario, 1984-1988.  


Ontario Ministry of Northern Development and Mines, Ontario Geological Survey

Survey Description

282 surface tills and 1100 till samples from sonic drill core were collected between 1984-88 in the Black River-Matheson area, north of Kirkland Lake and east of Timmins, Ontario. The data are published in Ontario Geological Survey Open File Reports 5749 (surface tills) and 5800 (till from sonic drilling).

Data Description: Paper report; data lists on diskette (ASCII) released separately as MRD-1 (Miscellaneous Release-Data 1).

Quantities Analysed: <0.063 mm fraction and total matrix (<2 mm ground to <0.074 mm) by INAA for Au, As, Sb, Cr, Co, U, and W; by DCP after HNO3-HCl extraction for Cu, Pb, Zn, Ni, Mo, Ag, Mn, Cd and Fe; by XRF for Ti, Zr and Sr; by GF-AAS after total digestion for Te; by fire assay-DCP after HNO3-aqua regia for Au; total matrix fraction also analyzed for major oxides by XRF

Geochem Plots Available: Proportional symbol maps show dispersal of Au, As, Sb, Cu, Ni, Zn, Co, U, and W (OGS OFR 5749). Proportional symbol maps showing the dispersal of elements; depth profile plots for boreholes (OGS OFR 5800).

Other Analyses: Grain size (<2 mm), carbonate by Chittick), heavy mineral concentrate for point counts and geochemical analysis (OGS OFR 5749). Heavy mineral concentrate for gold grain counts and non-magnetic heavy mineral grain counts; grain size; carbonate (<0.074 mm fraction by Chittick) (OGS OFR 5800).

Project History

1984-1991 BRiM Project: Black River-Matheson till sampling survey carried out in 1984-1988.
  The Black River-Matheson (BRiM) project is an interdisciplinary, multi-year (1984-1988) geoscience project initiated to stimulate mineral exploration, discovery and development in an area centered on the town of Matheson, Ontario. Reconnaissance scale till sampling and geochemistry was one component of the project and was designed to document the regional Quaternary stratigraphy and to provide baseline till geochemical data. Data published in Ontario Geological Survey Open File Reports 5749 and 5800.
