外生成矿作刚主要在大气圈、水阁与地壳农而的交界处,基本是在常温常压条件下发生的。在风化分界作用、沉积分界作用和成岩分界作条件下,有用物质得到集中形成为工业开采利用的地质体—矿体。风化分界产生风化矿床,并为沉积矿床的形成提供物园基础;沉积分异产生沉积矿床或矿源层,成岩分异使矿源层巾成矿物质活化、迁移、集中,形成层控矿床。
Exogenous mineralization just in the atmosphere, water Pavilion and the crust and the junction of the crust, basically occurs at room temperature and pressure conditions. Under the conditions of weathering demarcation, sedimentary demarcation and diagenetic demarcation, the useful substances are concentrated to form the geological body-ore body for industrial exploitation. Weathered demarcation produces weathered deposits, and provides the basis of the park for the formation of sedimentary deposits. Sedimentary differentiation produces sedimentary deposits or source beds. Diagenesis differentiation activates, migrates and concentrates ore-forming beds and deposits to form stratabound ore deposits.
