| Tartalmi kivonat: | A discussion of the current distribution rules of elements in rocks and minerals is given here. The criticism of the rules and the continuous trials of different authors to improve them is presented as well. Such discussion revealed the general dissatisfaction of the GoLDscHMiDT-rules. The authors found from their experience that the factor of the structure of the host mineral is very important in the fate of an element during magmatic crystallization. We recommend the following rule to be added to the existing rules for the distribution of elements: "The structrure of the host mineral is one of the determining factors in the allowance of elements into minerals". Various evidences from the analyses of coexisting mineral pairs are discussed in order to support this conclusion. |
