    A NEW EXPLORATION TO THE RARE EARTH ELEMENT VARIATIONS IN DUCTILE SHEAR ZONE: Discussion on the volume loss formula and reasons for REE variation

      摘要
    • 摘要: 通过对周建波等发表在《地质论评》上的文章《稀土元素在韧性剪切带体积亏损研究中的应用》的讨论，认为利用体积亏损公式来解释剪切带中稀土元素变异的原因值得商榷.详细分析了O'Hara体积亏损公式的原始推导，从而得出体积亏损公式的应用要视情况而定.提出体积亏损并不是剪切带中稀土元素变异的原因，仅仅是引起稀土元素变异原因的现象.流体作用引起的质量传输才是稀土元素变异的内在因素，并且根据前人的研究结果，概括了剪切带中影响稀土元素变异的其他直接和间接的因素：包括强应力作用下的部分熔融形成的融体对稀土元素（不相容元素）的“萃取”作用；副矿物的残留；氧逸度对稀土变异的动力学调控；高水/岩比环境下的流体有效渗滤；分配系数动态变化以及应力的驱动等.

       

      Abstract: In his article "The application of rare earth elements in the volume deficiency of ductile shear zone" published in Geological Review in 1999, Zhou explained the reason for REE variation with O' Hara's volume loss formula. However, a detailed analysis on the original derivation of O' Hara's formula shows that the application of the volume loss formula is conditional on cases. Actually, the volume loss is not the real reason for variation of REE in the shear zone, but just the phenomenon for the reason which causes the variation of REE. The mess transfer caused by fluid process is the essential factor for variation of REE. Based on previous researches, other direct and indirect factors for variation of REE in shear zones are summarized, including the "extraction" of melt to REE under strong stress, the residues of accessory minerals, the dynamic control of oxygen fugacity on variation of REE, the effective fluid filtration with high water/rock ratio, the dynamic changes of distribution coefficients, and the driving of stress on the elements.
