Trendall Web Site Tutorial


The purpose of this web site is to provide the results of my research to the public and the research community.

So far, three major products are available. These are a set of 1 sq. m photos of the Trendall locality, an interpreted geological map spatially associated with the images, and a set of Short Wave Infrared Reflectance (SWIR) spectra of locations within the Trendall locality. These can be used to assess what minerals are present in the rocks by examining the way light is reflected from them at certain wavelengths in the infrared portion of the spectrum.

In order to zoom in to a square meter photo from the overview maps or pictures, simply click on the region of the map you are interested in. You will go to a square meter page. From there, you may view the geological map of that square meter by clicking on the 'Geological Map' button. Clicking again hides the map. This allows you to get an idea of different rock units at the locality. If you disagree with the interpretation or find areas that have been incompletely mapped, I'd appreciate it if you let me know!

If a SWIR spectrum has been sampled within that square meter, a 'SWIR Spectra' button will be available. Click on that button will display the spectra. Clicking again will hide it. If one click doesn't work, try clicking again. It can't hurt. The SWIR spectra were taken by a PIMA instrument of the unprepared surface. For full details, please wait for a forthcoming paper. The geological map was inspired by previous work by Van Kranendonk and Hickman (2000).

To get a close up view of the photo, you may click on the photo itself. Be aware that the images are large - approximately 3Mb in size.

If you have any questions, not covered by this page, please email me. If you would like to investigate the web site now, click to go to the map page.
