苏、皖南部中、下石炭统之间普遍发育一套白云岩地层,过去通称为“老虎洞白云岩”。 自夏邦栋(1959)创建“老虎洞白云岩”以来,对它的时代归属一直存在分歧。杨敬之等(1962)把它与广西大埔白云岩相比,将它归入中石炭世早期;陈敏娟等(1964 1972,1980)、肖立功(1982)根据南京龙潭、汤山、孔山等地所获得的珊瑚化石资料,将它归入早石炭世晚期。江苏区调队(1972)、安徽区调队(1979)依据南京
A set of dolomite strata have generally developed between the middle and lower Carboniferous rocks in the southern Jiangsu and southern Anhui Provinces, commonly known as “tiger cave dolomites” in the past. Since Xia Bangdong (1959) created the “Tiger Cave Dolomite,” there has always been a disagreement over its age. Yang Jingzhi et al. (1962) compared it with the Dapu dolomite in Guangxi and classified it as early Carboniferous. Chen Minjuan et al. (1964 1972, 1980) and Xiao Ligong (1982) The obtained coral fossil data, it will be classified as early Late Carboniferous.
