Crushing effects on TL and OSL on quartz: relevance to ...

2000-12-15 · The effect of crushing on the TL and OSL signals in quartz was investigated to examine the feasibility of using OSL and TL for dating of faulted rocks. 275°C TL signals were not reduced by crushing by hand (mortar and pestle), in a pellet die press, or using an automatic mortar and pestle, but the sensitivity of the 100°C TL signal to a test dose decreased in crushed samples.

Crushing Quartz Samples

 · None had nice gold showing, most had no gold showing but were quartz, from a district known for producing high grade, and made my GM1000 sing. None were good candidates for specimens, none really made the detector scream, so I thought these were good bits of rock for crushing.

Stirling was a small mining settlement on the Haunted Stream goldfield situated in rugged mountain country between Bairnsdale and Omeo. Alluvial gold had first been discovered in the area in 1863, causing a small rush that soon petered out. The discovery of several rich quartz reefs between 1882 and 1884 led to a revival, with the expanding settlement formed near the junction of Tierneys Creek ...
