Micromorphology of cave sediments
Link to publisher version (URL)
Cave sediments are commonly fine grained and lack macroscopic sedimentary structures. Only a detailed analysis of the micromorphological characteristics permits an accurate determination of the sedimentary dynamics of such cave deposits. Microscopic sorting, grading, clast orientation, lamination, intercalation, deformation structures, and porosity are some of the features used to identify microfacies such as lacustrine, slackwater, debris flow, slumping, sheetwash, hyperconcentrated flows, and solifluction. In combination with micromorphological data derived from post-depositional diagenetic trends and anthropogenic evidence, it is possible to reconstruct the evolution of a cave, and the climatic history and landscape evolution of the area.
