| Abstract: | A large number of dioritic enclaves are distributed only in a restricted part of the Dajushan biotite-adamellite pluton, East Zhejiang. The characteristics of their distribution, shape, structure and texture show that they are quenched enclaves and are the products of the mechanical mixing of two magmas of different composition at different temperatures. It is believed that the simulation experiments of magma fountain by Campbell et el. can be used to explain the formation of this kind of enclaves. The fact that the enclaves and the host rock are comagmatic and that the former is relatively rich in high-field-strength elements such as Zr, P, Ti, REE, etc. suggests that origin of the enclaves may be magma immiscibility between the two corresponding magmas. |
