The main diageneticstage and relevant rock types are the Middle Proterozoic assemblage of gneissoid granodiorite-adamellite and the Sinean schistosity diorates.
主要成岩期及代表性岩类有：中元古界为片麻状花岗闪长岩-二长花岗岩，震旦纪为片理化闪长岩。

By the discussion of the effective controlling factors, sedimentary facies are the main factors of reservoir development in the region, and the diageneticstage is the secondary factor.
However, in the a period of later diageneticstage, laumontite were dissolved by organic acid which was generated in decarboxylation of kerogen, and a great quantity of secondary pores were formed.
