View of The Upper and Lower African Surfaces, Mvurwi Section

Grid Ref (WGS84 Lat/Long in decimal degrees)

-16.678228, 30.867508
Location: 
A road-side stop on the Horse Shoe Road which is off the road from Mvurwi to Guruve
Stratigraphy: 
Great Dyke Erosion Surfaces
Description: 

A road-side stop between Mvurwi and Guruve to view the topography of the Mvurwi section from the south side.

 

Note the following:

1.       On the left is the markedly planar Lower African Surface dominated by a dissected mesa terrain at a cliff-top elevation of ca. 1525m.

2.       In the near- and middle-distance, the low granite plain and inselberg landscape to the south of the Great Dyke is the Post-African Surface. On the left is the isolated granite inselberg of Nyambari with a summit elevation of ca. 1500m, only slightly less than the Lower African Surface on the Great Dyke serpentinites to the rear.

On the right is the Upper African Surface, here dominated by rounded summits including Mvurwi Peak (1738m).
