In addition, 3 outcrops in the Chiahsien area were involved into this study, which including Ssutehsiang, Paiyunhsiangku, and Niupu. Purposes of this fieldwork have two folds. One is to compare the specific occurrences of carbonate-cemented mudstones in TKS, HKS, PPS, FS, and those in the Chiahsien area. The other is to recheck Hayasaka's descriptions (1932) about the unique occurrences of fossil lucinids bivalves and fossiliferous marls of Chiahsien and the southeastern Shoushan.

A schematic model was proposed to illustrate the occurrences of various lithologies and lithofacies associations. The erosional surfaces on siliciclastic mudstones, funnel-shaped structure, and the exhuming of massive cold-seep carbonates exposed might have been occurred concurrently during a tectonic unstable time in SW Taiwan. The deposition of fossiliferous mudstone interfingered with the conglomerate lithofacies, and represented the rapid facies transition from siliciclastic (non-carbonate) into carbonate environment.

By studying reservoir rock characteristics, diagenesis and physical property, investigation showed that there were distributary channel, branch channel, mouth bar, distal bar, sand sheet, lakeshore, shallow lake and limestone flat . we concluded that the reservoir of N1~N21 is low porosity and permeability reservoir with the types of primary porosity and secondary intergranular porosity, which is in the early diagenetic stage B into the late diagenetic stage A subperiod. The role of effecting reservoir physical property is deposition, cementation, dissolution and tectonic rupture. After researching of reservoir, we divided it into three categories and division the favorable facies belt and relatively favorable. We think that the favorable facies belt is braided river delta front and partly shallow lake in east of the Fault Ⅶ. favorable reservoir is in the first and the second class.
