Posted: Jan 17, 2024 09:17 Post subject: Looking for help identifying rock samples |
|

Samples of rock pieces, and according to my personal definition, they contain magma, but I want to confirm their location in western Libya, close to the Tunisian border.
Mineral: | Magma |

This rock appears to be a breccia made up of broken clasts cemented together by some secondary material. It could be volcanic--there are volcanic rocks south of Tripoli, in NW Libya, But that's pretty hard to tell from photographs. It might help to provide more complete information on where you found it. The breccia could have come from a fault zone or from explosive volcanic activity..

I did not see the source of this sample, but its owner assured me that it came out of the ground and was in a sandy area, perhaps hidden by sand. According to my friend’s description, it resulted from a weak volcanic eruption that perhaps did not come to the surface of the Earth at that time, but due to erosion and weathering factors, it emerged on the surface of the Earth. It is on the northwestern border of Libya with Tunisia...
