| 中文摘要: |
| 通过对胶东旧店金矿床的构造及其演化特征和成矿作用的研究,说明构造活动释放能量导致了金的活化,构造的分布和差异性所产生的能量不均匀性是金元素迁移、沉积的动因,是控制金矿形成的主导因素。 |
| 英文摘要: |
| The investigation on structures and their evolution in Jiudian gold ore deposit proves that gold mineralization is closely related to tectonism. Analysis for gold contents of various geological bodies and distributions of S and Pb isotopes indicate that metallogenetic materials derived from Archean-Proterozic metamorphic rocks. During the formation of folds in E-W strike, gold in the old strata reactivated and differentiated to form gold-rich zones spreading in E-W strike. And in the faulting of NE to NNE structural zones, gold migrated further and accumulated into rich ores along the faults. Finite element calculation and holographic elastic experiment on syn-metallogenetic stress field show that gold ore deposits occurred generally in those portions with relative middle-lower strain energy value in higher strain energy area. Tectonic movement provides energy for reactivation of gold from strata. Differences of energy in various portions controlled migration and accumulation of gold. This knowledge is considered as a new guide for exploration of gold. |
