在岩溶作用所形成的喀斯特洞穴中,由于重力或地下水的作用而产生的沉积物。主要见于石灰岩岩溶发育的喀斯特地区。常见的洞穴沉积物有洞穴角砾岩,产生于石灰岩地区的洞穴内,为顶壁坍塌堆积而成,其特点是具角砾化,填隙物为碳酸盐物质或其风化后的红土物质。此外,洞穴沉积物中还普遍发育有钟乳石等化学沉积物。
岩溶洞穴沉积物形成于湿暖、干冷交替的环境;
They formed in the environments of humid warm and dry cold climate in turns.
洞穴沉积物不仅具有旅游开发价值,而且蕴含了丰富的古气候环境信息。
The sediments in the cave are of not only the value for tourism development, but also rich information of paleoclimate and paleoenvironment.
以洞穴调查的实际资料为依据,对洞穴沉积物中的边石坝结构类型进行了研究。
