Actually greenstone are always green. It is more prominent when fresh, but even weathered greenstone have a greenish tint. Greenstone belts are called so due to the presence of rocks with a green colour, but they do also contain rocks of other colours, but these are not greenstone.

We stand corrected. The examples at the WSBG with the polished part shows that the weathered parts of the rock are much less obvious green than the polished or newly broken parts. We mortals tend to miss it in nature.

It's also much harder if your perception of "green" is the colour of a certain beer bottle :D

No, actually it is a kind of mineral which has a green colour (but it is not found in greenstone belts!)

KEPs I am sorry to dissapoint you but if you think you have a tame geologist, it is actually the other way around. You are the one who are well trained to stop at the right outcrops :twisted:

Outcrops, and road cuttings......., and intrusions........, and dykes..........and......

People are generally ignorant of the fact that it all boils down to the geology of an area that will ultimately determine the game viewing potential of that area. A certain type of parent rock gives you a certain type of soil under certain climatic conditions. On a certain type of soil a certain type of vegetation will grow which will attract certain types and concentrations
of herbivores, which in turn will determine the type and concentration of predators in that area.


The graniter kopjies in the southwestern part of the park are hundreds of millions of years old.

Slightly off topic, I hope that is OK. :redface:
Which particular larger mammal of the Kruger exists well on this granite rich geological area?

Rhino?

(And I thought the strata in the west of the park were thousands of millions of years old. Skillie?)

I was just about to say kimberlite too, even though I don't know anyting about geology, and fortunately see that Imberbe has already done so. Thus, if its correct he can be IT :lol:
