There are two types of peridotites within this UHP belt.(1) Garnet peridotite consists of garnet lherzolite, garnet-bearing dunite, garnet-free dunite and garnet pyroxenite, which could be considered as one of the critical rock types in a continental-type subduction zone.

The mineral chemistry, trace elements and Sr-Nd isotopic geochemistry of different types of deep-seated inclusions indicate that Group Ⅰinclusions in western Shaudong could be the relicts of high degree of partial melting of the mantle-derived peridotites and then subjected to mantle metasomatism; the dunite and harzburgite in Group Ⅱ inclusions could be resulted from the metasomatism of silica-rich melts in the upper mantle; the olivine-pyroxenite and pyroxenite in Group Ⅱ and Group Ⅲ inclusions could be magmatic cumulates derived from magma underplating in the upper mantle.

不同结构类型深源岩石包体的矿物化学、元素和同位素地球化学研究表明，鲁西具有变质变形结构特征的橄榄岩类岩石包体为岩石圈地幔橄榄岩部分熔融后的残留体，其后又遭受了地幔交代作用的改造；具有变质变形结构，并叠加有矿物反应结构的纯橄岩和方辉橄榄岩类包体为古老岩石圈地幔被富硅质熔体改造的结果；具有残留岩浆结晶结构的橄榄岩、橄辉岩类岩石包体以及具有变晶结构或堆晶结构的辉石岩类包体为地幔更早期岩浆作用的在上地幔的堆积体。
