摘要
研究表明,断裂构造作用引起造岩组分的调整再分配导致REE迁移,且REE在贫Si富Al的构造岩(带)富集。断裂构造作用不改变REE的总体分配型式,但可引起轻、重稀土发生一定程度的分异。
Faulting could adjust the petrochemical composition of tectonites and make them redistributed at faults. The process of petrochemical-compositional redistribution might cause REE to migrate between tectonites at faults. And REE were enriched in tectonites (or tectonic zones) where the petrochemical composition Al was enriched and Si descended. Faulting was unable to change the REE distribution patterns of tectonites at faults, but couldcause differentiation occurring between LREE and HREE.
