Abstract

Samples of lichen-covered and bare lava surfaces from Lanzarote, dating the 1730-1736 eruption, have been analysed using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) to investigate the relative roles of biological and inorganic weathering processes. Lichens here grow preferentially on N and NE facing surfaces and create a range of nanomorphological features as a consequence of their weathering activities. This research in Lanzarote, in comparison with the previous studies in Hawaii, provides a test for the climatic-control model
