The Meridian Project, Ontario, 1992-1993

Ontario Geological Survey

Project Description

The Meridian Project is based on a new approach to low density geochemical mapping. It was designed as a pilot project leading to the future preparation of a geochemical map of Ontario.

The objective of the Meridian Project is to examine the feasibility of geochemical mapping on a province-wide scale in Ontario. Mapping was based on samples collected at 10 km intervals in 10 km wide corridors along the 80^th and 90^th meridians from the south to the north of the province.

Each 10 x 10 km micromodule was divided into quarters (5 x 5 km) and a sample was randomly taken in each quarter then combined to form a composite sample representing the micromodule.

The work was published as detailed below:

Year	Meridian	OGS Publication
1992	89^th	OFR5907 and MRD014
1993	90°45’	MP162, p. 265-267
