Leucosome sizes in migmatites has been shown to follow power-law distribution, which is indicative of self-organized criticality governing accumulation and transport of partial melts in anatexis. In our measurements of leucosome widths in the Olkiluoto migmatite in western Finland, we found double power-law distributions in addition to single power-law distributions. We divided the double power-law behaviors into those with positive and negative kinks separating the two power-law regimes. We propose that double power-law distributions in migmatites result from impediments on the bottom-up self-organized criticality that melt transport processes commonly display. These impediments can be caused by some leucosomes solidifying before others, in which case the leucosomes were effectively formed in two distinct events or phases. We also consider the emergence of double power-laws as a result of melt accumulation in and sudden melt removal from conduits of a specific size.

已经证明，在辉石中的白血球大小遵循幂律分布，这表明自组织的临界控制了无铅矿中部分熔体的积累和运输。在我们对芬兰西部Olkiluoto migmatite的白细胞宽度进行测量时，除了单幂律分布以外，我们还发现了双幂律分布。我们将双重权力法行为分为具有正面和负面纽带的行为，将两种权力法制度分开。我们提出，由于熔融运输过程通常表现出的自下而上的自组织临界性的障碍，导致了蒙脱石中的双重幂律分布。这些障碍可能是由于一些脂质体先于其他固化而引起的，在这种情况下，该脂质体在两个不同的事件或阶段中有效形成。
