Francois, you have simply failed to comprehend what teevee is trying to explain to you. Perhaps this comparison will help. Suppose for comparison that I have a pot of soup boiling on the side burner of my barbeque in Saskatoon and it is -30 degrees outside with a foot of snow on the ground. If the soup remains on the heat source until all the propane is gone it would continue to bubble away until all of the water has been boiled out and what remains is eventually baked onto the pot. If I took the pot of soup (before it was boiled dry) and threw the soup onto the ground spreading it widely, the soup would be almost instantly frozen and there would be minimal melting and mixing in with the snow. And if I simply removed the soup from the heat source and let it cool, it would eventually freeze but much more slowly than if I threw it on the snow. There would be a difference in the crystal size and characteristics in the ice crystals in the soup depending on exactly what kind of soup it was and on exactly how fast or slowly it cooled and froze. And of course on exactly how much water was left in the soup at the point that I took it off the burner. When the kimberlite magma was pushed into the dyke-sill-conesheet it was relativey quickly removed from the heat source and the surrounding rock would quickly absorb the heat from the magma with minimal melting and mixing with the country rock. This would yeild a significantly different result than if the material had been in a pipe which surfaced to the atmosphere. In a pipe which surfaces to atmosphere hot gasses from deep down would continue to surge through the magma bringing heat and potentially liberating gaseous carbon which might otherwise condense and solidify into diamonds. Diamonds are a crystal form of carbon and they are very sensitive to the specific and particular conditions of their creation. The other factor to consider is the pressure. We know that it would take tremendous pressure to inject the kimberlite into the granite. The pressure from the rising pipe probably created the crack and injected the magma into it spreading the crack at the same time. It would be reasonable to think that the pressure was not significantly releived in the same way as a break to atmosphere would releive the pressure. Therefore there would be no opportunity for gaseous material to escape before being condensed and cooled within the magma. It is kind of like making perfect fudge. Heat it too much and you ruin it. Don't heat it enough and it is just not right. I hope this helps.
