There is, however, clear evidence for a marked shift towards wet climate at the beginning of the Holocene \[9.8.4\]. This period is well-documented in the form of pollen-rich thick clay sediments in Didwana and several other lakes, and its onset is dated by ¹⁴C to \*c.\* 10000 B.P. According to Allchin \*et al.\* this wet phase is represented on the younger dunes in the form of calcium carbonate concretions and root casts formed by leaching from sand in a moist climate. It is with this wet phase that these authors associate the arrival of the makers of microlithic industries. Several ¹⁴C dates obtained from these concretions at Budha Pushkar range between 6500 and 3000 B.P. - [Previous: v1.c14.s2.21](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s2.21) - [Next: v1.c14.s2.23](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s2.23) - [Up: v1.c14.s2](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s2) --- Source: [https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s2.22](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s2.22) · Pramāṇa
