Description of the Square terrain in Cimei Township
Chimei Islet is a segmented square mountain islet. The land is roughly flat, and successively stretches down from east to west. There are steep cliffs along east coast. The height above sea level is about 66 meters, more than 30 meters in the midland, and down to more than 10 meters when it comes to west coast, just like an inclined tableland.
The sides of the north islet are surrounded by hills, forming a small basin terrain. There is a small brook in the middle of basin flowing toward west and going under the sea from Eagle Tower on the west side, which is the gap. This terrain is divided into two villages, West Lake and East Lake villages.

Geological description of Cimei Township
Pillar basalts stand erect on the south, east and north coasts, forming a spectacular terrain landscape. For example, the sea cliff terrain of Big bay, Niumu level ground, Northeast bay and Northwest bay etc, the dike terrain of Amah Rock, and special Pillar basalt of Big Lion Scenic Area all grow on very well. The bottom of this pillar basalt is the mixed layer of yellowish-brown sandstone and slate-grey mudstone; there is quite thick tuff sandstone between them. For example, the Tingshi area is the horizontally mixed area of the stated deposited rocks. Moreover, around Niumu level ground and Lungcheng, we can see dikes of igneous rock above waters, folded layered tuff edge conglomerate, thick layered sandstones, mudstones and the wave erosion platform formed by water erosion.
