What does the sedimentary record of a giant meteorite impact look like? Turns out it is full of tsunami breccia, fine ash, hail-like spherules, and a barium-rich ocean's crystal precipitates. Join us in the Barberton Greenstone Belt of South Africa to learn

GIGAmacro views of komatiite

Erik Klemetti posted today at Eruptions about komatiite, which is apropos, considering I just finished imaging some samples of that ultramafic volcanic rock. Have a look at three samples from Barberton Greenstone Belt here, each from the 3.27 Ga Weltevreden Formation: Link GigaPan by Callan Bentley Link GigaPan by Callan Bentley Link GigaPan by Callan Bentley And, while we’re at it, here’s one from the Red Lake Greenstone Belt (~3.0

It was five years ago when I first visited Sea Point, the outcrop on the coast of the Cape Peninsula where the Cape Granite (~540 Ma) intrudes the (meta-)sedimentary rocks of the Malmesbury Group. The outcrop is (a) beautiful and evocative, and (b) of historical importance, as Charles Darwin visited it while on the voyage of the Beagle, contemplating and confirming Lyell’s assertions of the validity of plutonism as he

Friday fold: isoclinal fold in ferruginous pelite and chert of the Fig Tree Group

A quick Friday fold – Ulundi Formation, basal Fig Tree Group of the Barberton Greenstone Belt, exposed in a creekbed etched into the trace of the Sheba Fault. This is one of the outcrops I visited one week ago today as part of the pre-IGC field trip to the Barberton. The rocks are iron-rich cherts and pelites that have enjoyed some serious strain, presumably due to movement along the Sheba

Martin Schmidt again contributes a fold – this time from his summer trip to South Africa: Pretty great! This is part of the Cape Fold Belt. Perhaps some of you will drive by it when you go to the International Geological Congress in South Africa later this month! You can view the site in the context of Google Street view here.

L'inattesa (ma non troppo) possibilità di tyrannosauroidi (giganti) africani

 BE,
Nel terzo più bel film sui dinosauri nella storia del cinema, un iper-vitaminico e ipo-realistico Spinosaurus fa letteralmente a cazzotti con un Tyrannosaurus. Aldilà della ovvia implausibilità biomeccanica dello scontro, l'obiezione classica verso quella scena è che spinosauridi e tyrannosauroidi giganti non si sono mai incontrati, dato che i due gruppi sono noti in differenti regioni

Che settimana entusiasmante! Machimosaurus rex, del quale ho raccontato la scoperta, anatomia e implicazioni evoluzionistiche, sta avendo un meritato risalto mediatico.

Nel precedente post, ho raccontato l'epica giornata del 6 dicembre 2014, in cui scoprimmo lo scheletro articolato di un enorme coccodrillo fossile nella località di Touil el Mhahir, nel sud del Governatorato di Tataouine, in Tunisia. La nostra squadra ha estratto l'esemplare dal sedimento tra il 6 ed il 7 dicembre. I colleghi tunisini trasportarono poi l'esemplare, opportunamente impacchettato
