From what I can gather according to Mungall's theory, if the stack of rocks in the center of the RoF was inflated so to speak, we can possibly surmise that this secondary event, pluton, komatiitic magma flow, etc, pushed upwards and domed the rocks.
The image in the above slide, obviously from an unrelated exploration project, would have been perhaps a good example of what it looked like originally, but as the heat and force exerted pressure on the central area, this is perhaps where a trough would develop along the base, and the melted ceiling rocks would have run down the sides of the dome to what is now the Ring of Fire. This secondary upheaval may well have been the event that turned the outward-lying intrusions on their side as well, and would explain the folding that occurred. And since we know that there was a thin layer of iron formation, this would have been introduced to the melt at that time, as well as the felsic rocks which would have over-saturated the magma with more silica ( felsic essentially stands for Fel= feldspar + the "sic" represents silicic rocks...of which granite is one we have in abundance)
What I would dearly like to know, is that if the intrusions are now flipped on their sides, and ultra mafic filled dykes have broken off from their source in the upheaval process, does this mean that the connecting conduit lies beneath the chrome, as Mungall has said it would have precipitated to the lowermost portion of the flow? I'm just trying to wrap my head around where the conduits are now, roughly speaking, if they have not been remobilized.
I could be completely wrong in referencing the above image, but nothing ventured, nothing gained.
I know the drills will ultimately tell the tale, but I've always been notorious for trying to guess the surprise endings in movies and books.... GLTAL
