Based on summarizing magnetic parameters and vicissitude and evolvement of environmental magnetic minerals,this paper introduce the main advances made in many fields such as soil and atmosphere contamin.

The result shows that the magnetic mineral is mainly composed of ferrimagnetic with different grain sizes,such as multi-domain,stable single domain and super-paramagnetism.

The grain-size analysis and magnetic property measurements of late Cenozoic sediments of borehole SG7 in the Yangtze delta plain have revealed the evolution of dominant magnetic minerals with time and coupling effects of neotectonic movement, climate and sea level changes on the sediment provenance and depositional environment.

Review in the identification of magnetic minerals;

Based on the researches in the last two decades,a brief review of the types and transformation of magnetic minerals in the marine sediments and.

Study on environmental magnetic characteristics was conducted on the Xuzhou urban topsoils and the results indicated that the magnetic characteristics were dominated by the multi-domain / single domain ferri-magnetic minerals.

This paper introduces the main classification of active minerals, and suggests that the major factors affecting mineral activity are degree of amorphous derivative, chemical components, water quenching condition, and the fineness of min.

Pyrite, chalcopyrite,sphalerite and a-quartz are common minerals in gold ore deposits and also are gold-carrier minerals and polar minerals (semiconducting minerals, thermoelectric minerals ).
