Such changes may be either worldwide or local; if they are worldwide they are called eustatic. The changes caused by transgression and regression of sea on land are found preserved in the coastal areas in the form of high-level sea-beaches, beach-rocks, coastal fossil dunes and the geomorphic forms like marine plantation surfaces, ria-type valleys of the streams, wave-cut caves, platforms, etc. Occasionally prehistoric cultures are found in association with these deposits; thus they provide important evidence for dating the cultures radiometrically or stratigraphically. - [Previous: v1.c14.s8.t2.25](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s8.t2.25) - [Next: v1.c14.s8.t2.27](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s8.t2.27) - [Up: v1.c14.s8.t2](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s8.t2) --- Source: [https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s8.t2.26](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s8.t2.26) · Pramāṇa
