在变质作用过程中,岩石内的铀和其他含矿元素的活动性,依据以下地球化学和岩石资料以及实验结果的研究来证实。 (1) 铀是容易活动的元素,在各种地质过程中(包括在区域变质作用下)。都能在合适的条件下迁移。 (2) 铀的矿物成分、本底含量和它在原生(变质作用前)岩石以及变质岩石中的存在形式对铀的活
During the metamorphism, the activity of uranium and other ore-bearing elements in the rock is confirmed by the following geochemical and rock data and experimental results. (1) Uranium is an easily accessible element in a variety of geological processes (including under the influence of regional metamorphism). All can migrate under the right conditions. (2) Mineral composition of uranium, background content and its activity on uranium in the presence of native (pre-metamorphic) rocks and metamorphic rocks
