These wild ostriches (two female on the left hand side, one male on the right) are lined up alongside the boundary between the Congo and the Kalahari cratons in southern Namibia. The craton boundary is marked by a visible fault scarp. (c) Geology for Global Development 2013
Muon musings – how penetrating particles could let us peer beneath Mars’ surface
Muons are penetrating particles generated by cosmic rays. Muon radiography – or muography – is the large-scale equivalent of using x-rays to generate images. Except, instead of using x-rays to take a closer look at your broken arm, we can use showers of muons to take a look inside large geological structures – we’re talking …[Read More]

Friday Photo (83): Wildlife in the Field – Giant Millipede Inspects Stromatolites
A giant millipede kindly provides a scale for a photo of some stromatolites in the Nama group, Namibia. Microbial communities grow upwards towards the light. Each growth phases is cemented by carbonate grains that stick to the sticky EPS substance that the communities produce, forming layered stromatolite columns. The stromatolites pictured above formed 550 million …[Read More]
