Slice of Martian Meteorite Teghaza 001

Scientists have studied a thin slice of Teghaza 001, described as one of the most ancient Martian meteorites ever found on Earth. The specimen was employed to determine the rock’s age, providing data that contributes to broader understanding of Martian geological history.

Reflected‑light images of the slice serve as a detailed road map for researchers, guiding them to minerals of interest that can be examined further with a range of analytical instruments. Figure A presents the same image with additional visual detail, illustrating how the imaging technique supports mineral identification.
