"This report contains U-Pb geochronological results for 16 rock samples from the Southern Indian Lake, Lynn Lake and Kisseynew domains of northern Manitoba collected between 1999 and 2002. While results from other samples collected during this time interval were published previously, the results included here were not, primarily due to uncertainty about the interpretation of the results. The purpose of this report is to release the existing data with the required sample and laboratory metadata along with a limited, preliminary interpretation so that this information is available for consideration by future researchers. This report contains two Excel spreadsheets, each containing the results for either isotope dilution thermal ionization mass spectrometry (ID-TIMS, Appendix 1) analysis or sensitive high resolution ion microprobe (SHRIMP, Appendix 2) analysis conducted at the Geological Survey of Canada. Each spreadsheet consists of a worksheet containing the data and a series of sheets containing the concordia diagram for each sample. For the six samples analysed by SHRIMP, the scanning electron microscope zircon images annotated with the SHRIMP spot location are included as separate Adobe pdf files. Details for each sample (location, lithology, interpretation of results) are given below and a summary of the interpreted age is provided on an accompanying kml file to be viewed in GoogleEarth"--Description of content, page 1.
