Abstract

Examination of weathering rinds from lava flows on Hawaii with backscatter electron microscopy and electron microprobe analysis reveals that olivine weathers more slowly than adjacent clinopyroxene and plagioclase in environments with a paucity of organic acids. Yet when wheathering rinds are in contact with abundant organic acids secreted by lichens, olivine weathers before clinopyroxene and plagioclase weathers last. This illustrates the importance of the biogeochemical environment
