Tricorder Tech: Astrobiological Applications Of μ-mapping X-ray Fluorescence Spectrometry

by Keith CowingMarch 22, 2024March 22, 2024

Many low-temperature planetary surface processes leave traces of their actions as features in the size range from 0.01 mm to several mm. Syn-sedimentary, authigenic and diagenetic features at the higher […]
