摘要
本文论述了山东喀斯特洞穴的分布、成因类型及形态特征、洞穴沉积物特点。并探讨了山东古溶洞的形成时代、发育演化等问题。
There are more than 340 karst caves in Shandong Province, which have been known so far. These caves are distributed mainly in the mountain areas of Central - Southern Shandong, the most in Lushan region and a few in Yiantai - Penglai region of the Northern Jiaodong Peninsula According to hydrodynamic conditions during the time when the caves were formed and taking into account the present location of caves in underground hydrodynamic zone, the author divided the caves into four major genetic types, and gave a general enunciation of morphological character for each kind of cave and speleothems in Shandong.
The status of cave development in various strata is studied in the paper. Statistics of 247 caves show that the Second and Fourth Members of the Majiagou Formation of the Middle Ordovician and the Zhangxia Formation of the Middle Cambrian are strata containing the largest number of caves in Shandong.
Researches on formation time and evolution process of the caves was made on the basis of analysing of geomorphological and palaeoenvironmental change. The author point out that caves in Shandong were mainly formed since Neogene, and that from late Miocene to Middle Pliocene was the main period of cave development.
