Chemical Remagnetization: Testing for Relationships with Basinal Fluids and In Situ Diagenetic Processes

虽然人们普遍认识到许多沉积单元是通过化学过程被再磁化的，但对其具体机制仍知之甚少。盆地/造山带流体的迁移是化学再磁化的一个可能原因，但可能需要就地机制来解释流体不渗透单元中的化学再磁化。该项目将1)测试盆地流体与再磁化之间的关系，2)测试几种原位化学再磁化模型。虽然该项目强调古地磁方面的研究，但预期的结果应该对MVT矿化的时间和起源，岩/流体相互作用的性质以及流体在碳酸盐岩单元中的流动具有重要意义。

Although it is widely recognized the many sedimentary units were remagnetized by chemical processes, the specific mechanisms are still poorly understood. The migration of basinal/orogenic fluids is one likely cause of chemical remagnetization, but in situ mechanisms may be needed to explain chemical remagnetization in units that were impermeable to fluids. This project will 1) test for a relationship between basinal fluids and remagnetization, and 2) test several models for in situ chemical remagnetization. Although this project emphasizes the paleomagnetic aspects of the research, the expected results should have important implications for the timing and origin of MVT mineralization, and the nature of rock/fluid interactions and fluid flow in, and through carbonate units.
