This study was conducted to obtain the mineral composition of the various fractions of Harmattan
dust separated according to their specific gravities. Soil dust is a major constituent of airborne particles in the
global atmosphere. The generation and transport of dust are processes that continue to this day, playing an
important role in geochemical and geophysical processes, including the addition of nutrients to soils and to the
oceans. Mineral dust suspended in the atmosphere interacts with the solar and earth’s thermal radiation thereby
affecting the climate radiative budget. Studies on the Harmattan dust mineralogy were carried out after
separation into six fractions by means of heavy liquid solutions. The major components were; quartz, haematite,
illite, micas, feldspars, kaolinite and chlorite. There is increased interest in the properties of small airborne
particles because of the role that they play in many environmental processes. Much of this interest stems from
the possible impact of aerosol on climate-related processes that involves radiation and cloud. For this reason
aerosol, studies are focused on the chemical and physical properties of aerosols that relate to radiation and to
hygroscopic behavior.
Key words: Harmattan dust, heavy liquid solutions, kaolinite, mineralogy, Northern Nigeria, quartz,
