Fig. 2: Low-temperature curves after magnetic extracts.

From: Stalagmite paleomagnetic record of a quiet mid-to-late Holocene field activity in central South America

Magnetic mineralogy from magnetic extracts of stalagmite DBE50; (left) Curves of Field-cooling (2.5 T) (black circles) and Zero-field cooling (gray circles) measured on warming; (right) Curve of room temperature saturation isothermal remanent magnetization (RTSIRM); the Verwey transition (~120 K) which is characteristic of magnetite is signaled by the drop observed in the cooling curve (black circles).
