Abstract

The AA. review here the capabilities of 2 types of Schmidt Hammer (Classic N type and Silver Schmidt BL type) alongside 2 types of Equotip (standard type D and Piccolo) for investigating rock hardness in relation to rock weathering on various types of sandstone and limestone, as well as basalt and dolerite. Whilst the 2 Schmidt hammers and the 2 Equotips show comparable results when tested at 15 individual sites, interesting differences are found between the Equotip and Schmidt Hammer values which may reveal information about the nature of weathering on different surfaces. The 4 instruments were tested in 2 locations : the Golden Gate Highlands National Park in the Free state, South Africa, and along the Dorset coast in southern England. Results and discussion
