摘要: 福建省广泛发育的侵入岩，应用岩石谱系单位划分、归并的新理论、新方法，划分有１１０个单元，归并成２７个超单元（序列），２１个独立岩石单元，初步建立起全省岩石谱系单位等级体制。Ｍ、Ｉ、Ｓ、Ａ型花岗岩均较发育，Ｓ型花岗岩一般缺少大规模的火山喷发，Ｉ型、Ａ型和Ｉ型与Ｓ型过渡型花岗岩，具有滞后或与火山活动同时、同源、规模相当、地域相应的规律。不同时期、不同岩石谱系单位，成矿类型及规模不同。
Abstract: By using the new theory and method of hierarchical division and clustering, the intrusive rocks in Fujian province are divided into 110 units and incorporated into 27 super units （sequences） and 21 independent rock units and a hierarchy system of rock units of the whole province is preliminarily established. In the province, M , I , S and A type granites are all well developed; large scale volcanic eruption is generally lacking in S type granites; whereas I andA types and transitional type of I and S types have the features of originating after or simultaneously with volcanic activity and from the same source as volcanic rocks and being equivalent in size and areal extent to volcanic rocks. Different hierarchical units of the intrusive rocks formed in different periods have different mineralization types and scales.
