In this paper, the Yixian Formation is divided into five eruption cycles. The paper describes the main features of the agates belonging to body-like secretory type and fracture filling type in Yixian Formation and related cryptovolcanic rocks in Fuxin area. Some conclusions have been reached: the stratabound characteristics of the agates of these two genetic types are obvious; they mainly originated in the eruption cyclesⅠandⅡof Yixian Formation; the agate veins of the fracture filling type is primarily in the NNW-NNE direction; the sequence of favorable ore rock is andesitic melaphyre, related cryptovolcanic clastic rocks, basalt and volcanogene clastic rocks. On such a basis, it is pointed out that the agate of the fracture filling type is the major genetic type in prospecting for agate in the future, and that the key prospecting areas are Zidoutai-Qijiazi and Laohetu-Shijiazi.
