%X The Changle-Linqu region is situated in the middle Shandong Province, and at the Western block of the Yishu fault belt of Tanlu Fault. There are more than 200 volcanic hills, mainly occurring in the Miocene, Pliocene and Pleistocene in the region. The geological settings, occurrences, facies and the developing characteristics of the fractures and pores of volcanic rocks are systematically investigated in this paper. Four main pore systems are recognized: (1) the volcanic channel facies pore system, characterized by the well developed macro-fracture, semi-fill and pillar-plane joints; (2) the volcanic lava facies net pore system composed of various kind, scale, occurrence, evolution of joints, fractures and pores; (3) volcanic eruption facies pore system, and (4) eruption-deposition facies pore system. The quantitative models of the pore systems are also primarily established.
