Regionalno-geološke karakteristike miocenskih sedimenata na prostoru severnog Banata
Dejan N. Radivojević (2014-12-30)Predmet doktorske disertacije predstavljalo je rešavanje strukturno‐stratigrafskihodnosa miocenskih sedimenata na prostoru severnog Banata. U cilju regionalnogsagledavanja, korišćeni su svi raspoloživi geofizički i geološki podaci sa širegistražnog područja, odnosno iz celog Panonskog basena i susednog orogena. Osimklasičnih metoda primenjene su i savremene metode seizmostratigrafije,tektonostratigrafije i riftne sekvencione stratigrafije. Primenjene metode omogućilesu izradu modela progradacije ivice šelfa za ceo Panonski basen, modela uzajamnihveza između basena i geodinamičkog modela jugoistočnog oboda basena.Jezero Panon je većim delom zapunjeno prilivom sedimenata paleo‐Dunavom saseverozapada, odnosno ...Centralni Paratetis, Panonski basen, miocen, jezero Panon,seizmostratigrafija, sekvenciona stratigrafija, paleogeografija, geodinamika...

Legal framework for recultivation of degraded areas caused by mining exploitation
Radmila Gaćina (2023)Prilikom površinske i podzemne eksploatacije uglja eksploatacioni sistemi oštećuju veće ili manje površine zemljišta. Iskustva pokazuju da su oštećenja zemljišta znatno veća kod površinske eksploatacije, gde je prostora degradiran ne samo u konturi rudnika i okoline, već se promene takođe dešavaju u prirodnom okruženju. U članku su predstavljeni rezultati studije zakonskih okvira rekultivacije u nekim zemljama sveta i u Srbiji. Praktično iskustvo rekultivacije pokazalo je da iskorišćenje i devastacija tokom rudarske aktivnosti predstavljaju opasnost ne samo za pogođena ...... g of the recultivation obligation policy in the Mining Act based on the understanding of preventing environmental damage and also for humans.

The use of biological markers in determination of origin and type of organic matter in the Tisza river sediments
Snežana Štrbac, Gordana Gajica, Aleksandra Šajnović, Nebojša Vasić, Ksenija Stojanović, Branimir Jovančićević (2013)The objective of the study was to determine the origin and type of organic matter (OM) of the Tisza recent sediments along the distance of 153 km through the territory of Serbia. For this purpose group organic-geochemical parameters and biomarker compositions were used. All samples contain approximately same amount of OM, which was deposited under uniform, slightly reducing conditions. Based on the distribution of n-alkanes, the origin and type of OM could not be precisely estimated. However, n-alkane patterns ......

Palinomorfe sa lokaliteta Gostuška reka (Stara planina)
Ivan Rutović (2024)U radu su prikazani rezultati palinološkog istraživanja permsko-trijaskih sedimenata sa lokaliteta Gostuška reka. Palinološki kompleksi su detaljno analizirani, što je omogućilo morfološku, taksonomsku i paleoekološku identifikaciju palinomorfi. Istraživanje je pokazalo prisustvo velikog broja spora i polena golosemenica, dok je polen skrivenosemenica zastupljen u manjem procentu. Na osnovu paleoekoloških analiza, zaključeno je da je tokom formiranja sedimenata na lokalitetu vladala aridna klima, sa povremenim vlažnim fazama koje su omogućavale razvoj močvarne vegetacije.... lakši pristup palinološkom materijalu.
