===Drift geology===
There is a variety of drift deposits in Port Talbot. Sandfields area of Port Talbot is built upon blown sand and [[tidal flat]] deposits. These were deposited by the wind via [[aeolian processes]] and the water by [[fluvial processes]]. Velindre area of Port Talbot is built upon an alluvial fan deposit. This deposit formed during the last glacial period 14,000 years ago. Baglan Road in Port Talbot is built upon glacial till from the [[Last glacial period|Devensian]] period. Till, also known as [[boulder clay]], is a mix of unconsolidated sediment with a range of grain sizes. This forms as the fronts of glaciers rapidly deposit material due to melting. Cwmafan in Port Talbot is built upon [[Alluvium|alluvial]] and [[glaciofluvial deposits]], formed from glacial [[meltwater]]. Baglan Moors, Fairfield and Port Talbot town centre are built upon tidal flat deposits (tides were higher 12,000 years ago allowing sandy deposits to accumulate).{{citation needed|date=December 2016}}
