Introduction

2012-11-15 · Soils encountered at the site were generally observed to be of a typical basaltic weathering profile with dark brown, clay rich soils extending to a depth of 0.3m overlying highly weathered residual basalt cobbles set in a pale, dry kaolinite clay which in turn overlie basaltic bedrock which was encountered at a depth of approximately 0.6m.

2016-6-29 · The code 21 basalt has given slight weathering problems which are not serious and the code 56 basalt has been also judged as a phonolite or even a dolerite. This material is, however, too fine in texture to be a dolerite and it can''t be a phonolite because phonolite is a tertiary rock which is much younger than the Jurassic basalt of the Karoo ...
