For the first time, synchronous correlation technique and amino acid racemization (AAR) analyses of Patella spp. Thetystrombus latus shells are applied to an understudied sequence raised palaeoshorelines refine knowledge about terrace phases uplift history in middle-late Pleistocene a sector Apulian foreland (western coast Salento Peninsula, southern Italy). These combined methodologies provide chronological attribution for quantitative assessment vertical crustal movements this foreland, which, date, has been characterised by scarcity reliable data.By applying driven new AAR analyses, we iterate different rate scenarios find best match between digital terrain model field-based observed "expected" sea level highstand elevations.Our results show that two could explain mapped geomorphology: (i) scenario 1 suggests fluctuating rates over time with 0.15 mm/y until 130 ky BP (middle Pleistocene, interval MIS 15 - 6; is, 590 BP) 0.07 from present; on other hand, (ii) 2 constant 0.12 Pleistocene.The recognised study related following highstands: 119 (MIS 5.5 second peak), 125 5.5), 240 7.5), 340 9.3), 478 13.1) both 2. The only differ oldest palaeoshoreline: 560 15.3) 550 15.1) 2.Our highlight how number preserved is controlled rates; indeed, area, fewer than regions where higher have beeninferred, suggesting more prominent effect "overprinting" or re-occupation younger highstands older highstands. Finally, discuss geomorphological geological implications using approach, age controls, relatively low within well-known geodynamically stable regions, such as Italy.
