豹斑灰岩又称豹皮灰岩。这种特殊的石灰岩,在华北广泛分布,在碳酸盐岩剖面中占有较大的比例。就早古生代地层而言,它占19.8％左右。在华北这种岩类最发育的还是奥陶系,它占29％左右。因此,引人关注。解放前,前辈地质学家们在描述华北奥陶纪地层时,就运用了豹皮灰岩这个名称,形象的描述了这种花斑状的石灰岩。后来一直为地质工作者所沿用。对其成因也曾经作过一些研究。但专 Leopard spot limestone, also known as Leopard limestone. This special limestone, widely distributed in North China, accounts for a large proportion of carbonate rock profiles. For the Paleozoic strata, it accounted for about 19.8%. In North China this rock or the most developed Ordovician series, it accounted for about 29%. Therefore, attract attention. Before the liberation, the predecessor geologists described the North China Ordovician strata, the use of leopard skin limestone name, describes the image of the piebald limestone. Has been followed by geologists. There have also been some studies on its causes. But specifically
