Rad je objavljen u \u010dasopisu otvorenog pristupa Frontiers in Earth Science, pod sekcijom Sedimentology, Stratigraphy and Diagenesis, i mo\u017ee se vidjeti na poveznici<\/a><\/em>. <\/strong><\/p>\n

U radu je multivarijatnom statisti\u010dkom analizom geokemijskih podataka pokazana geokemijska varijacija izme\u0111u razli\u010ditih horizonata kr\u0161kih boksita u Hrvatskoj, s cljem utvr\u0111ivanja evolucije Jadransko-Dinarske karbonatne platforme (ADCP). Pokazano je da je vremenska os uklju\u010dena u tektonostratigrafsku shemu te da ukazuje na promjenjivu paleogeografiju i dinamiku talo\u017eenja na jadranskoj karbonatnoj platformi kroz razdoblje od gornjeg trijasa do miocena. Tri diskriminantne funkcije tuma\u010de se u smislu tipi\u010dnih procesa postanka boksita na karbonatnoj platformi tijekom emerzije, kao \u0161to su napredak boksitizacije i unos mafi\u010dnog materijala u sastav protoboksita, procesi progresivne feralitizacije i, kona\u010dno, desilikacija. U kona\u010dnici, gornjokredni boksiti su najrazvijeni boksiti s vrlo visokim udjelom aluminija i niskim sadr\u017eajem silicijevog dioksida, koji je u rangu samo s paleogenskim boksitima. Me\u0111utim, sve ostale skupine boksita, osim miocenskih, impliciraju “nedovr\u0161eni” proces kemijskog tro\u0161enja tijekom kratkih perioda emerzije karbonatne platforme. Gornjokredni boksiti pro\u0161li su proces deferalitizacije, dok geokemijski signal najmla\u0111ih miocenskih boksita, kao najmla\u0111eg produkta boksitizacije u hrvatskim kr\u0161kim Dinaridima tek neznatno odstupa od modernih tala (terra rossa) zahvaljuju\u0107i visokom sadr\u017eaju minerala glina, odnosno niskom stupnju boksitizacije. Dokazan je diskriminiraju\u0107i potencijal u geokemijskom sastavu boksita, koji ujedno ukazuje na mogu\u0107e promjene koje su utjecale na razvoj Jadransko-Dinarske karbonatne platforme tijekom razdoblja emerzija, \u0161to se mo\u017ee primijeniti i na razvoj drugih karbonatnih platformi.<\/p>\n
