New paper about Luizi impact structure, Congo


New paper about Luizi impact structure, Congo


Dear friends,

There is a new paper about the Luizi impact structure in the Congo. 
It is;

Ferriere, L., F. G. R. Lubala, R. T. Osinski, and P. K. Kaseti, 
2011, The newly confirmed Luizi impact structure, 
Democratic Republic of Congo—Insights into central uplift 
formation and post-impact erosion. Geology. vol. 39, no. 9, 
pp. 851–854. doi:10.1130/G31990.1; 4

"Because of its preservation state and the shape of the 
structure, with an inner ring, the Luizi crater also provides 
insights into the formation of mid-sized impact craters on 
Earth. Ferriere and colleagues estimate that the crater was 
made by the collision of a kilometer-wide asteroid with a 
speed of about 72,000 km per hour. However, based on 
their investigations, they can only say that the crater is 
younger than about 575 million years, the age of the rocks
that have been excavated."
