Mtshingwe Dyke View

Grid Ref (WGS84 Lat/Long in decimal degrees)

-20.396641, 29.903121
Location: 
Approximately 20km from Zvishavane on the Bulawayo Road.
Description: 

The dominant feature of the view is the distant peak of the uppermost ironstone of the Bend Formation known as Mberengwa. The smaller “false” peak to west is one of the lower ironstones which cap the ultramafic to mafic lava sequence constituting the Bend Formation. The Peak marks the axis of a steeply plunging, NE trending syncline which affects all formations up to the lower parts of the Zeederbergs.

 

Above the Bend Formation is a locally developed conglomerate and agglomerate of the Koodoovale Formation, which is unconformably succeeded by the upper greenstones.

 

In the near and middle ground from this vantage point are pyroclastic and mafic rocks of the Hokonui Formation and the low distant hills of the Gurumba Tumba Complex lie to the south and SW.

 

The view point is supported by a dolerite dyke of Proterozoic age which follows the ESE trend of the Mtshingwe Fault. Extensions of this dyke cut the Great Dyke to the west.
