Scan of the Cetaceous/Paleogene boundary in Raton Basin US

Thin sections measurements(64-bit OS)

Trace elements in garent 
Thin section of a garent containing slate
Full area map shows symmetric Mn core within the crystals
Selected garnet neasured extensively with strong primary filter to reduce background and to avoid Bragg diffraction peaks
370 pixel×460 pixel→170000 pixel map
Measurement time:1 s/pixel
Steps:25μm

Summary
Unique speed and perfoimance in the determination of the element distribution in large sample with measurement tiomes per pixel of 0.3 ms and up tp 4 Million pixels in a single Hyper Map
High spatial resolution down to 25 μm X-ray spot size,motors steps of 4 μm
Optimal for the analysis of inhomogeneous samples,due to better identification of the representative location of interest
Non-destructive,fast analysis of large samples without preparation,including solid,power oe liquid samples
Qualitative and quantitative analysis of all elements from Na upwards,due to vacuum chamber,detection limit for heavy trace elements in the low ppm range
Standardless Fundamental Parameter quantification with type calibration option
Powerful Software with multiple tools for optimal data mining
