Large samples that are difficult to divide into smaller pieces, such as rocks, can be loaded into the XGT sample chamber as is. Wide range mapping can be performed over a maximum area of 10 cm x 10 cm.
Procedures such as elemental mapping can also be performed easily, and penetrating X-ray images can be obtained for rock samples up to 25 mm thick.

There is no way to examine element distribution over a wide area with conventional systems.
Analysis of a Granite sample.
It is thought that when granite is subjected to weathering, iron in black mica is leached down through the rock. With the XGT, a wide area of the sample could be mapped, making it possible to investigate the effects of sample weathering without needing to cut or process the granite sample.
