Soil, Till Ontario 2000

Soil and till sampling survey, NTS 52H/4, Legris Lake property, northwestern Ontario, 2000.  


Ontario Ministry of Northern Development and Mines, Ontario Geological Survey

Survey Description

32 humus, 30 B-horizon soil and 35 till samples were collected on the Legris Lake property in 2000. Two sampling lines over sites of greater than 300 ppb combined platinum and palladium were positioned parallel to the latest ice-flow direction. Samples were spaced at 25 m intervals and were taken up and down-ice of known mineralization. The data are published in Ontario Geological Survey Open File Report 6054.

Data Description: Paper report with data lists. Digital data available separately as MRD-71 (Miscellaneous Release-Data 71).

Quantities Analysed: <0.177 mm fraction of humus and <0.063 mm fraction of till by ICP-AES for 25 elements; by ICP-AES-FA for Au, Pd, and Pt; and ICP-MS for 51 elements.

Geochem Plots Available: Proportional symbol maps show dispersal of selected elements.

Other Analyses: Heavy mineral concentrate from 77 till samples for gold grain counts and metamorphic or magmatic massive sulphide and kimberlite indicator minerals; pebble lithologies for 77 till samples.

Project History

2000-2001 Northwestern Ontario soils and till sampling surveys carried out in 2000.
  A total of 242 soil, till and vegetation samples were collected at 8 sites in northwestern Ontario in 2000. The objective of the project was to sample surficial materials of known platinum group element (PGE) occurrences and assess how surficial geochemistry may be applied to PGE exploration. The data are published in Ontario Geological Survey Open File Report 6054.
