Corsi 674, approx. 145 x 73 x 40 mm, © Oxford University Museum of Natural History
| OUMNH Number: | 674 |
|---|---|
| Name and quarry location: | Basalte listata, possibly from Wadi Hammamat, Eastern Desert, Egypt |
| Geological description: | Most probably a metagreywacke, a metamorphosed turbidite deposit with sand to silt sized particles. |
| Comments: | There has been some confusion over the numbers of the ancient basalts in Corsi's collection. Mary Porter wrote in 1964 that 'Nos 674-678 inclusive - Italian labels on specimens - the numbers are out of order according to descriptions in the Corsi Catalogo ragionato. There are two specimens labelled 161.3.' This does not however account for the fact that none of Corsi's 'basalti' are in fact basalt, a dark extrusive igneous rock. |
