Abstract
U ovom radu istražene su mineraloške, strukturne i morfološke značajke mineralnih čestica koje su izdvojene iz suspendiranog materijala tijekom pojave koloidnog bijelila, mliječno bijele suspenzije, u poluzatvorenom, krškom morskom jezeru na otoku Mljetu (Jadransko More). Čestice su analizirane metodom rendgenske difrakcije (XRD), pretražnim elektronskim mikroskopom s visokim razlučivanjem (FE-SEM) te metodom laserske difrakcije (LD). Rezultati su pokazali da su igličaste čestice dominantna mineralna faza u suspendiranom materijalu tijekom pojave bijelila, dok je analiza rendgenske difrakcije tih čestica potvrdila prisutnost aragonita. Granulometrijske karakteristike, morfološke značajke i strukturne pojedinosti igličastih čestica aragonita potvrdile su značaj novog modela kristalizacije, odnosno koncepta mezokristalnog rasta u njihovom nastajanju. Osim toga, ovo istraživanje dokazuje ulogu biološki potaknute anorganske precipitacije na nanorazini u formiranju aragonita u ograničenom mediteranskom okolišu.
Abstract (english)
Abstract: This study examines mineralogical, structural and morphological characteristics of mineral particles originating from suspended matter during the formation of whiting events, drifting milky clouds of water, in a semi-enclosed, karstic, marine lake on the island of Mljet (Adriatic Sea). The particles were examined by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), as well as laser diffraction (LD). The results have shown that the needle-like particles were the dominant mineral phase in suspended matter from whiting, while XRD analysis of these solids confirmed the presence of aragonite. Granulometric characteristics, morphological features and structural details of the aragonite needle-like particles confirm the significance of the nonclassical, mesocrystal growth concept in their formation. In addition, this study exemplifies the role biologically induced inorganic precipitation processes at the nanoscale in the formation of aragonite a restricted Mediterranean environment.
