Research on The Stalagmites Sedimentary Chronology——A Case Study on No.1 Stalagmite of Shuinan Cave in Guilin, China

The stalagmite P1,P₂ of Panlong cave and stalagmite X1 of Xiangshui cave in Guilin(which their ages are 30 ka BP,over 350 ka BP and 56ka BP,respectively),the stalagmite D3, D4 of Dongge cave and stalagmite Y1 of Yaman cave in Libo(which their ages are from 64 ka BP to 19ka BP,over 155 ka BP and from 53ka BP from 7.3 ka BP,respectively),the stalagmite Q14,Q16 of Qixing cave in Duyun(which their ages are from 64 ka BP to 19ka BP,over 155 ka BP and from 53ka BP from 7.3 ka BP, respectively ),Guizhou,and the stalagmiteLL1,LL5 of Linhua cave in longshan(which their ages are from 60 ka BP to 21a BP,and from 80 ka BP from 6 ka BP,respectively),Hunan,have been studied and integrated for many years. The characteristics of depositional cycles,micro-lamina and bedding plane structure in large stalagmites with height from 150cm to 400cm have obviously typicalness and representativeness.
