Hi, thanks for your very enjoyable presentation. I'm wondering if you wouldn't mind expanding a bit on the method for mapping the melt inclusions. In particular, what is the resolution on your maps and how long did it take to acquire them?
Hello Ayla, thank you for your interest! For the high-resolution mapping the laser spot size is approximately 0.7 micrometer, and the spatial resolution of the map grid is 1 micrometer, that is given by the XYZ stage resolution. The mapping time really depends on the signal to noise ratio, which, in turn, depends on the depth of inclusion below the surface (30-90 um). Near surface inclusions can be mapped in 2-4 hours, while the deeper inclusions can take up to 14 hours. Another variable and limiting factor is of course, the size of the inclusions.
