隐生代是用来指代地球月球地质演化的最初时期的非正式术语,它是冥古宙最老的一代,一般认为其开始于约45亿3300万年地球和月球形成时。[1]

目前尚无法模拟地球和月球形成时的模型来描述月球上从隐生代至接下来的盆地群代之间是如何过渡的(另见前酒海纪),但有时会以41亿5千万年前做为此一时期的结束。[2]不只这个时期,并连冥古宙的其他子分类也都没有被国际地层委员会正式地承认。此一时期的资料不多,因为只存在着极少的地质资料。大多数的地形和岩石大概在初碰撞期时就已经被摧毁,或因板块移动的持续影响下而消失掉。吸积地球、其内部的物质分离以及融化的地表凝固和假想中形成月球大碰撞也是发生在此一时期。现知最古老的矿石亦出现于隐生代时。[3]
