3月16日,记者带着“安龙金字塔”的视频和网友们的问题,采访了贵州师范大学地理与环境科学学院(喀斯特研究院)教授周秋文。他说,安龙金字塔山体就是自然形成的,不过是大自然的鬼斧神工让山形呈现出棱角分明的金字塔形状而已,并非网友调侃的人工修建、古墓遗址之类,不必过度解读。
记者:“安龙金字塔”山上的岩石为什么表现出一层一层的特征?
周秋文:安龙县的这些山体属于喀斯特地貌,形成这些山的岩石是距今约2亿多年前(三叠纪早至中期)的白云岩,这种岩石是在海洋环境下形成的,当时整个贵州大部分区域都在海底。这些白云岩是在海洋环境下由水中溶解的矿物质重新结晶形成的。由于气候、地质构造等环境因素发生周期性变化,使得岩石形成过程反复中断后又重新开始,所以形成的岩石表现出明显的分层特征。
