Time-Dependent Microscale Evolution of Mineral-Filled Fractures in Deep Shale During Water Immersion: Insights from Fixed-Field SEM–EDS Imaging
The morphological evolution of mineral-filled fractures in low-clay shale during water exposure remains poorly understood, particularly regarding how infilling mineralogy, fracture geometry, and fluid accessibility control the response. In this study, fixed-field scanning electron microscopy coupled with energy-dispers...
