This impasse in the Ivory Coast is just another French plot by the same people and using the same collaborators. In summary, the colonial pact maintained the French control over the economies of the African states; it took possession of their foreign currency reserves; it controlled the strategic raw materials of the country; it stationed troops in the country with the right of free passage; it demanded that all military equipment be acquired from France; it took over the training of the police and army; it required that French businesses be allowed to maintain monopoly enterprises in key areas water, electricity, ports, transport, energy, just hook up forum not only set limits on the imports of a range of items from outside the franc zone but also set minimum quantities of imports from France.
These treaties are still in force and operational. It is probably very little surprise to other Africans that the attempts by Gbagbo to break free of these chains irritated the French.
The African Presidents were kept in power by French armies.
Pressure has nothing to do with it, and zircon crystals all have about the same density as their total lead content is small. Just what is it that a Cambrian stratum has which a Cretaceous stratum lacks. What does the Jurassic strata have that the Tertiary strata do not. If rock type mattered then we would expect a zircon crystal's lead content to vary dramatically within the Cambrian or Cretaceous strata according to their local rock types.
No, that's not what we observe. How about neutrinos or cosmic rays. Neutrinos penetrate the earth so easily that they would affect all strata more or less equally, to the extent that they affect anything at all.
