HWW Kimberley Northern Cape South Africa 2nd June 1982

HWW Kimberley Northern Cape South Africa 2nd June 1982
It's difficult to capture the depth of the "Big Hole" in Kimberley but the height of the buildings give an idea of the scale. It's a real vertical wall of rock.

Kimberlite, an ultramafic igneous rock and a rare variant of peridotite, is most commonly known to be the main host matrix for diamonds. It is named after Kimberley where diamonds were mined from this hole.

Kimberlite occurs in the Earth's crust in vertical structures known as kimberlite pipes, as well as igneous dykes and can also occur as horizontal sills. The consensus on kimberlites is that they are formed deep within the mantle, hence at high temperatures and pressures.

HWW to everyone. Have a great day!

An incredible hole here and a job to capture it without the deep shadows I guess. Wouldn't like to trip and roll down there. Thanks for sharing.

HWW, enjoy the day. Herb

Impressionnant contraste entre la ville à l'arrière plan et ce gouffre naturel, qui semble prêt à avaler les bâtiments! HWW.

That looks quite a frightening depth. I cannot imagine working down there.
Thank you for the interesting information Pete. Peridotite is the primary source of the peridot gemstone also I understand. It must have been a fascinating visit.

A very impressive hole indeed, Pete. I recall learning about these vast craters in geography classes (many years ago). HWW and best wishes.

Bigger than the Super Pit in Kalgoolie, Australia?

Probably not Graham but it's the the biggest hand-mined pit before it closed in 1914.

For hand digging, at a pace where the miner doesn't want to miss all the diamonds, it is huge.
