摘要
地球脉动引起地壳的生消和发展,表现为八重态——地台、膨胀期陆洼、收缩期陆洼、陆槽、海岭、膨胀期海洼、收缩期海洼、海槽。地壳演化的8种状态,制约矿产的时空分布,形成不同的成矿域和成矿幕。
The growth,subduction and development of the Earth crust are caused by Earth pulsation whichmanifests it self in cight different states-cctet mcdel.They are:1 platform,2 continental depressionat the Earth expansion period,3-continental depression at the Ear h contraction psriod,4-continentaltrough,5-sea ridge,6-sea depression at the Earth expansion pericd,7-sea depression at the Earthcontraction period,8-sea trough.These states govern the time and spacial distribution of mineral reso-urces and deeignate different metallcgenic provinces and episodes.
