Geological structure and neotectonic movements are two important factors responsible for the difference of various karst geomorphologic units in this area. Fengcong like karst landscape along the Juma River, and large - scale karst caves, such as Yunshui cave (survey), Shihua cave and Yinhu cave are developed there. (RB).

A new kind of microbanding, the transparent microbanding which is observed under the polarizing microscope, was found. A report of about 1100 continuously deposited bands taken from the upper part of 45 mm of the stalagmite is given. The AMS14C dating suggest that each banding represents one year, reflecting the variation of annual precipitation. (RB).

Shihua cave, 50 km to the southwest of Beijing developed in the Ordovician limestone and dolo-limestone.The Shihua cave has 6 levels with a total length of 2900 m. The sixth level is developed under the groundwater table. In summer, the fifth level is seasonally filled with water.The first and second levels of the cave system have been public since 1984. There are over 1000 shields and larger or smaller plates in Shihua cave, shields are the main attraction of the cave. According to their dipping, they may be classified as vertical plates like the stone walls, horizontal plates with some basket and declined plates. Based on the position against the root base, they may include cave roof shields, cave wall shields, shields parasitized on stalactites, stalagmites, columns even flowstone and plates. According to the plate structure, they may be drawn as monoplates, twin plates, x-plates and network plates. They may be divided into board plates, hair-brush plates, basket shields, mosquito-net shields and column shields. Referring to the relation between the plates and the features below them, most of the shields grow along fine fissures in the dolomitic rocks. Shields have been reported from many countries from tropical to temperate climatic zones. (author; RB).

Shihuadong (Stone Flower Cave) scenery area, 50km far from Beijing, is located at Nancheying village, Fangshan District, Beijing. The Shihua cave develops in the Ordovician Majiagou limestone on the northern limb of Beilin syncline. Cambrian and Ordovician limestone is about 3900m thick. In the study area, Shihua Cave, Kungshui Cave, Bailong yan and Yinhudong Cave systems each with over 1000m long have been discovered. In which, Shihua cave is only opened for the tourists. The magnificent, colourful and different size and kind of speleothems such as stalactites, stalagmites, flow stone, stone curtains, stone flags, helicties, columns, straws, hanging tubes etc. have been seriously protected. The Shihua cave is with high values of scientific research and tourism.

Spectral analysis of a 1000-year stalagmite lamina-thickness record from Shihua Cavern, Beijing, China, and its climatic significance The Holocene, vol. 9.6 (1999) : 689-694
Stalagmite laminae provide a high-resolution geological record of climate change. In this paper, moving spectral analysis is used to analyse a stalagmite lamina thickness record to study climatic variability. It was found that the dominant cycles of the lamina thickness sequence are 2, 3.3, 5-6, 10-12, 14-18, 133 and 194 years. Some of the cycles are the same as the cycle of modern climatic indices, such as the QBO (Quasi Biennial Oscillation) of 2 years, the QTO (Quasi Triple-year Oscillation) cycle of about 3.5 years, the QFO (Quasi Five-year Oscillation) cycle of 5-6 years and the QEO (Quasi Eleven-year Oscillation) cycle of 11 years. It was also found that there are different dominant cycles in different time periods. Usually, the dominant cycles are stronger in wet periods when the microlaminae are thicker. In dry periods, the microlaminae are thinner and the power of the dominant cycles is also weaker. Another feature is that the power of the dominant cycles and their long-term periods and frequencies appear to change. These phenomena are important for understanding the climate changes in Beijing area over the last 1 ka. (PYJ).
