Applications of micro-X-ray fluorescence mapping to iron bands in iron-oxide concretion to evaluate its formation and reaction rate

Abstract

: Fe oxide Liesegang bands have often been observed in sedimentary and igneous rocks, and they are formed during weathering and alteration by water–rock interactions. In this study, micro-X-ray fluo rescence ( μ -XRF) mapping was used to study the Fe bands in an Fe oxide concretion from the Jurassic Navajo
