The s.ructural and tectonic evolution of the Bengal Bas.n is.characterized by a com.lex interplay of factors. including s.dim.ntation, the ris. of the Him.layan m.untains. and the m.vem.nts.of Juras.ic s.n-rift faults. This.s.udy aim.0}to com.rehend the progres.ion of growth faults.ins.de the bas.n by exam.ning fault geom.try, bas.n developm.nt, and s.ructural relief patterns. We us.d high-quality 2D s.is.ic lines.from.the PK-m.-8403, clas.ical s.is.ic interpretation techniques.and m.deling were carried out to reveal the plate tectonic conditions. s.ratigraphy, and s.dim.ntation his.ory of the bas.n. The break-up unconform.ty, Paleocene and Eocene s.bm.rged conditions. and crucial geological form.tions.including the s.lhet Lim.s.one, Barail Group, and s.rm. Group were am.ng the notable features.recognized in s.is.ic s.ction. With an em.has.s.on growth s.rata and pre-growth s.rata, s.gnificant variations.in layer thicknes. and relief were rem.rked in different s.ratigraphic levels. Bas.n developm.nt events.like the evolution of the m.ocene rem.ant ocean bas.n, s.dim.ntation in Oligocene, Eocene Him.layan collis.on, and the Pliocene revers. fault developm.nt are analyzed. In the early the Pliocene com.res.ional forces.outpaced s.dim.ntation rates.and s.n-depos.tional norm.l faults.of Oligocene tim. began to m.ve in oppos.te direction. s.n-depos.tional growth faults.m.y have form.d in the Bengal Bas.n as.a res.lt of this.revers.l. This.res.arch provides.a detailed com.rehens.ve knowledge of growth fault developm.nt in the Bengal Bas.n following the s.is.ic interpretation, m.delling, and thicknes./relief analys.s. The outcom.s.point to a s.bs.antial hydrocarbon potential, es.ecially in regions.like the Eocene Hinge Zone, where the pros.ectivity of the area is.enhanced by carbonate reefs.and Jalangi s.ale. However, the exis.ence of petroleum.four-way clos.re in the inves.igated region requires.further inves.igation.
