Abstract
Na četiri sedimentne jezgre uzorkovane u sjevernom dijelu otoka Mljeta napravljene su paleookolišne i paleoklimatske rekonstrukcije. Razvoj taložnih okoliša prostora današnjeg Velikog jezera i uvale Stupa rekonstruiran je temeljem mineraloških, kemijskih i strukturnih obilježja sedimenta. Promjene su smještene u vremenski okvir temeljem starosti dobivenih analizom radioaktivnog ugljika, ali i upotrebom tefrokornologije. Ukupno je pronađeno 13 tefri, 9 ih je analizirano od kojih je 5 povezano s već opisanim erupcijama. Dvije tefre su nove, po prvi puta opisane erupcije Vezuva. Dobiveni podaci interpretirani su u skladu s njihovom kompozitnom prirodom. Razvoj taložnih prostora vezan je uz rast morske razine. Sedimentacija jezerskog sedimenta na prostoru Velikog jezera započinje prije otprilike 10.6 cal ka BP, jezerski sediment taložen je do prije 2.4 cal ka BP kada je intrudiralo more. U uvali Stupa jezerski sediment se počinje taložiti prije 11.5 cal ka BP i taloži se sljedećih 1.8 ka, kada u uvalu ulazi more.
Abstract (english)
The four sedimentary cores sampled in the northern part of the island of Mljet were used for paleoenvironmental and paleoclimatic reconstructions. The development of the paleoenvironment of the today's Veliko jezero and Stupa Bay area is reconstructed on the basis of mineralogical, chemical and structural features of the sediment. The time frame of changes is based on age obtained by analyzing radioactive carbon, but also by using tephrochronology. Thirteen tefphras were found in total, 9 were analyzed, of which 5 were correlated to the known eruptions. Two tephras are newly described Vesuvius eruptions. The obtained data is interpreted in accordance with their compositional nature. The development of sedimentation environments is linked to the sea level rise. Sedimentation of the lake sediment in the Veliko jezero area begins around 10.6 cal ka BP and it continius until before 2.4 cal ka BP when sea intruded. In the Stupa bay, the lake sedimentation starts before 11.5 cal ka BP and it lasts for 1.8 ka, until sea intrusion.
