Three zones are to be distinguished in the large intrusive bodies by the different degree of selforganization while their cooling and crystallization. Basically, this difference is connected with the rate of energy loss in crystallization process. Marginal parts of intrusion correspond to the quickly cooling zone with a minor self-organization. The next - intermediate zone, which contours are conformable to the outer intrusion contacts, was influenced by the high thermogradient and shows insignificant self-organization also. But in the innermost part of magmatic body the self-organization phenomenon reveals itself clearly: it causes the vertical zoning of intrusion. The rhythmical layering develops between lower (high temperatures) and upper (lowe temperatures) parts of the inner zone due to autowave crystallization process.
