研究岩石內磁性礦物的一個基本任務為了解天然礦物中殘磁的粒度依賴性與其穩定性，礦物的顆粒尺寸、形狀和結晶結構影響其磁區結構，岩石殘磁由岩石形成過程所決定其屬於之熱殘磁或是化學殘磁。前人量測磁學性質以巨觀研究為主，用於鑑定磁性礦物種類、特性、殘磁大小等，巨觀量測方法獲得資訊為岩樣中磁性礦物所有磁訊號的總和平均值，容易忽略或掩蓋掉微小的細節，且無法準確區分不同礦物之微觀磁區結構，因此，本研究利用微觀尺度量測方法磁力顯微鏡，分別對中洋脊玄武岩、紐西蘭假玄武玻璃以及臺灣西南部泥岩，三種不同區域、岩性的樣本，探討岩石形成過程對磁性礦物磁特性之影響，在奈米尺度下對單顆磁顆粒之磁區結構重建，並且量測磁場方向和推測其殘磁紀錄種類，輔助巨觀磁學量測無法解釋的細節。研究結果分別為：（1）中洋脊除了上部枕狀玄武岩中鈦磁鐵礦外，下部蓆狀岩牆中磁鐵礦之柵狀組織，以微觀磁學性質證實亦能貢獻海底磁性異常；（2）紐西蘭假玄武玻璃中，在微觀磁結構中，新生成磁鐵礦由顆粒尺寸主導，具有穩定方向單磁區之熱殘磁；（3）臺灣西南部泥岩，不同硫化鐵其生長時序與形狀異向性皆可能影響古地磁之判斷。這些結果與巨觀磁學研究相輔相成，磁力顯微鏡技術可以識別單個磁性礦物的微觀磁結構，並提供磁場方向（地磁場的指標），故研究結果顯示：磁力顯微鏡技術在地球科學領域上具有應用價值。

Paleomagnetism is the study of the record of the Earth's magnetic field in the rocks. The macro-magnetic analysis growth has completed, but micro-magnetic structure of magnetic minerals rarely known. We sought to reveal the growth process of magnetic minerals in the three types of rocks as it pertains to their magnetic domain structures. The studied including mid-ocean ridge basalts in the Southeastern Indian Ridge, pseudotachylyte in New Zealand, and mudstone in Southwestern Taiwan. In this study, a scanning electron microscope (SEM) equipped with the energy dispersive spectroscopy (EDS) were used for mineral identification, and magnetic force microscopy (MFM) was utilized to examine magnetic domain structures. The results supply that the source of ocean anomalies is not only carried by titanomagnetite minerals in pillow basalt but also magnetite in sheet-diked. The neoformed magnetite with consistent direction in the pseudotachylyte vein may be used as the indicator for geomagnetic field at that time. The timing of pyrrhotite or greigite formation can vary enough to give different remanence in mudstone. It suggests that care should be taken when interpreting magnetic data from sediments. The MFM technique can provide more magnetic information and is a powerful tool that can be potentially applied in the geomagnetic and geological fields.
