A Comparative Study on the Comminution Behavior of Diorite Rocks [PDF]
Dans cet article, les facteurs qui affectent le comportement de fragmentation des roches dioritiques hétérogènes obtenues à partir de deux sites de carrière au Botswana ont été étudiés. Les roches diorites sont très abondantes au Botswana et elles sont de plus en plus considérées comme un matériau de construction alternatif relativement peu coûteux et ...

The 3.5 Ga Siurua trondhjemite gneiss in the Archaean Pudasjärvi Granulite Belt, northern Finland [PDF]
In the Archaean Pudasjärvi Complex the pyroxene-bearing rocks are considered to form a belt, the Pudasjärvi Granulite Belt (PGB). The major rock types of the PGB are meta-igneous mafic and felsic granulites, and trondhjemite gneisses Red alaskites, white
