Web1 Jun 2001 · Magnetic properties (IRM, ARM, χ in, S ratio at 0.3T, room temperature (RT) hysteresis and thermomagnetic curves) and geochemical data (Fe, S, Mn, Al, Ti, organic C) were studied in two eastern Mediterranean boxcores (ABC26 and BC19) at a resolution of 3–5mm. The boxcores contain sapropel S1 (9–6kyr BP) at a few decimetres below seafloor. Web16 Aug 2024 · In rock: Magnetic properties The magnetic properties of rocks arise from the magnetic properties of the constituent mineral grains and crystals. Typically, only a small fraction of the rock consists of magnetic minerals. It is this small portion of grains that determines the magnetic properties and magnetization of the rock….
