An Investigation Using SiroSOM for the Analysis of QUEST Stream-Sediment, Lake-Sediment and Water Data (NTS 93 [all sheets], 94 A, 94B, 94C, 94D)
- Stephen Fraser, CSIRO Exploration and Mining
CSIRO Exploration & Mining (CEM) is undertaking an analysis of Geoscience British Columbia's "QUEST" geochemical data using SiroSOM, an exploratory data mining technology based on self organizing maps. CSIRO is responding to the Geoscience British Columbia's "Request for Proposals Analysis and Follow-up of QUEST Project Geoscience Data", which was posted on August 5, 2008 on the Geoscience BC web site.
SiroSOM is a data mining "analytics" technology that is capable of finding relationships within and between complex and disparate datasets. Previously, SiroSOM has been used for the integrated analysis of geoscience data sets, including geochemical assays, geology, mineralogy, 2D and 3D geophysical data sets, geophysically-derived petrophysical properties and even structural inputs. SiroSOM has the potential to assist in the analysis of "under-populated", complex or disparate datasets because it is based on the principles of vector-quantization. Various strategies can be employed to assist in the analysis depending on the nature of the available data and the scope of the analysis.
In this project specifically, SiroSOM will be used to establish relationships and domains within the various geological and geochemical data from the "QUEST" stream sediment, lake sediment and water data sets available from within the study area outlined on Figure 1.
CEM will conduct this activity in calendar year 2009. Outputs from the project will include delivery of GIS-compatible ASCII csv outputs and a report. It is intended that the results will also be presented at an appropriate workshop/conference in British Columbia.
