南海东北部居里面特征及其石油地质意义

Curie point isotherm is the temperature isotherm where ferromagnetic minerals in the rocks change from ferromagnetism into paramagnetism because the temperature increases to the Curie point. Below this isotherm,the rocks are thought to be almost non-magnetism because their temperature is higher than the Curie point.
