9804965 Kodama Sedimentary compaction may cause the remanent magnetism, acquired during sedimentation, to be significantly shallowed, resulting in incorrectly low paleolatitudes if not recognized. This project will examine inclination shallowing phenomena associated with chemical remanence in the laboratory and in a field example in China. Results are expected to clarify under what circumstances a chemical remanence can be affected by subsequent sedimentary compaction and to provide guidelines for recognition and possibly correction.

小行星9804965 沉积压实作用可能会导致在沉积过程中获得的剩磁显著变浅，从而导致不正确的低古纬度，如果没有认识到。 本项目将在实验室和中国的一个现场实例中研究与化学剩磁相关的倾斜变浅现象。 预计结果将澄清在什么情况下，化学剩磁可能会受到后续沉积压实的影响，并提供识别和可能的校正准则。
