KARAKTERISTIKA PANTAI DALAM PENENTUAN ASAL SEDIMEN DI PESISIR bAYAH KABUPATEN LEBAK, BANTEN
Abstract
Karakteristika pantai di daerah penelitian terdiri atas pantai bertebing dan pantai landai. Pantai landai dicirikan oleh morfologi datar berupa pasir lepas, sedangkan pantai bertebing dicirikan oleh morfologi bergelombang disusun oleh batuan keras yang masif, seperi batuan intrusif, batupasir dan konglomerat. Data bor yang diperoleh dari 10 lokasi di sepanjang pantai Bayah, menunjukkan bahwa bagian atas merupakan sedimen lanau-pasirsedang dengan ketebalan antara 50 cm sampai 110 cm, sedangkan sedimen pasir kasar terdapat di bagian bawah dengan ketebalan antara 120 cm sampai 210 cm.
