研究不整合面不仅能阐明地壳运动的性质和发展历史,而且在找矿勘探工作中也有实际意义。人们都熟知石油的聚集与不整合面有密切的关系。有些沉积型铝、铁、锰矿床产在不整合面上海浸岩系底部。某些风化淋滤型铁、铀矿床产在不整合面的情况也见有报导。古风化壳矿床也是产在不整合面上的。但是对不整合面在内生成矿作用中的意义却了解的很少。近几年来,在我国的一些内生矿床中发现不整合面上产出有岩浆侵 Studying the unconformities can not only clarify the nature and development history of the crustal movement, but also have practical significance in prospecting exploration. It is well known that oil accumulation is closely related to the unconformity. Some sedimentary aluminum, iron and manganese deposits are produced at the bottom of the unconsolidated shanghai boulders. Some weathered leaching iron, uranium deposits in the unconformity of the situation has also been reported. Weathered crust deposits are also produced in the unconformity of the surface. However, little is known about the implications of unconformities in endogenic mineralization. In recent years, some endogenous deposits in our country have found that there is magmatic invasion on the unconformity surface
