Magnetic Inclination

The upper limestone consists of aragonitic and calcitic limestone with little or no evidence of dolomitization. The thickness of this unit appears to be highly irregular; the maximum known thickness of about 20 m is within the Mutalau Reef at Fonuakula, but the unit is thinner elsewhere on the Mutalau Reef and apparently thins or disappears in the Mutalau Lagoon ( Schofield and Nelson, 1978 ).

Magnetite & Lodestone | Mineral Photos, Uses, Properties

Rock magnetism is the study of the magnetic properties of rocks, sediments and soils.The field arose out of the need in paleomagnetism to understand how rocks record the Earth''s magnetic field. This remanence is carried by minerals, particularly certain strongly magnetic minerals like magnetite (the main source of magnetism in lodestone).
