地质骨架许多矿床,包括大多数重要矿床,都产在波罗的地盾的前寒武纪地层中,而且大多数是分布在22—18亿年的建造中。加里东期建造含有许多矿床,其中有些具有十分重要的经济意义。古生代地台盖层,除瑞典有铀矿床外,都几乎没有矿床产出。波罗的地盾是由35—6亿年的前寒武纪建造组成的。它们至少包括三次造山运动。最老的太古宙造山运动,影响了地盾东部和北部28亿年前的地层。芬兰和瑞典的大
Geological Skeleton Many deposits, including most of the most important deposits, are produced in the Precambrian stratigraphy of the Baltic Shield and are mostly found in 2.2-18 billion years of construction. There are many deposits in the Caledonian period, some of which are of great economic importance. Paleozoic platform cover, in addition to uranium deposits in Sweden, are almost no output of the deposit. The Baltic Shield is made up of 3.5-6 billion years of Precambrian construction. They include at least three orogeny. The oldest Archean orogeny affected 2.8 billion years ago in the eastern and northern parts of the shield. Finland and Sweden are big
