In comparison, researchers had successfully implemented multimodal imaging in the light microscopy and medical imaging communities. In total, the evidence that Lo et al.

Jessberger and Dominik3 have presented data to support an earlier result4 according to which the 40Ar gas retention ages of some white inclusions from Allende exceed the canonical age of the Solar System.

The extensive investigation of the Allende meteorite has provided much new information on the early history of our Solar System. The research team developed a SQUARREL (scattering quotient analysis to retrieve the ratio of elements) method to retrieve quantitative information on elemental composition of the complex ptychography images.

Researchers studied Allende well at the time as research laboratories were well prepared to receive lunar samples from the Apollo program.

For instance, while electron microscopy can offer unmatched atomic resolution, the method only applies to very thin samples. The Allende meteorite was observed in Mexico on February 8, 1969, as a CV3 carbonaceous chondrite.

Agreement NNX16AC86A, Is ADS down? The imaging results revealed many internal textures and channels to suggest shock veins and melt aggregates on the meteorite. & Wasserburg, G. J. J. geophys.
For this, they collected 2-D ptychography images of the grain to pinpoint locations of each element with high contrast and spatial resolution.

Some meteorites, particularly primitive chondrites, are quite unlike any other type of rock found on Earth and can be readily identified. In the larger meteorite matrix, they observed long internal channels ranging from 20 to 50 nm in diameter to suggest shock veins. Jessberger, E. K. & Dominik, B. Use, Smithsonian 71, 1249–1269 (1966). The findings include small but significant anomalies of the isotopic composition for several elements which are clearly not due to any of the processes hitherto known to cause such variations (see ref. The team quantified the Ni and Fe composition in the iron-nickel sulfide region using the SQUARREL method (a semiquantitative ptychography analysis method) to reconfirm the identity of the compound, previously only predicted using EDS.
