Measuring rock hardness in the field (2014)
Book Chapter
Mol, L. (2014). Measuring rock hardness in the field. In J. Nield, & L. Clarke (Eds.), Geomorphological Techniques. British Society for Geomorphology

Rock surface hardness is often used as an indicator of the degree to which a rock surface has weathered. As the surface deteriorates the loss of cohesion results in crumbling of the surface, increased pore water circulation and dislodging of sections...

Book
Mol, L., & Sternberg, T. (2012). Changing deserts: Integrating people and their environment. Cambridge: White Horse Press

Deserts—vast, empty places where time appears to stand still. The very word conjures images of endless seas of sand, blistering heat, and a virtual absence of life.
