Die verandering van die wandgesteentes in die omgewing van die ertsliggame van Rosh Pinah

Abstract

Abstract provided by author:

Three types of altered arkosite are present around the ore-body. Chemical comparison of the different altered arkosites was done using suitable diagrams and the conclusion was made that the mineralization is related to the alteration processes of silicification, potassium alteration (sericitisation) and carbonatisation. These alteration processes have also had an influence on the foot wall as well as the hanging wall arkosites, especially the silicification- and carbonatisation processes

No simple relationship between ore occurences and wallrock alteration that can be helpful in exploration, could be identified

Fumarolic activity within a marine miogeosynclinal and sedimentary environment, contributed to ore genesis
