RE:RE:RE:RE:RE:RE:RE:RE:RE:Surrounding rocks Lit up.There is clearly a sedimentary layer in the graphic. And the stratigraphy leaves no doubt as to the orientation of the layers at the time of deposition.
This is important because sulfides settle due to gravity. Accumulations should therefore be found along the contacts of magma/ surface lava flows, at the bottom of the melts.
diabase1 wrote: Furthermore, in both the Kambalda and Shaw Dome Timmins area, most of the ore-bearing komatiites are directly underlain by sulphidic sediments (Coad 1979, Lesher 1989). Many believe these sediments are the source of sulphur that became incorporated in the komatiitic magmas and gave rise to the ores.
I thought that I read this somewhere and here it is. Just some thoughts about the Grasset Complex.
