Palynofacies and geochemical analysis of Oligo-Miocene bituminous rocks from the Moldavidian Domain (Eastern Carpathians, Romania): Implications for petroleum exploration

A palynological, palynofacies and geochemical investigation conducted on Oligo-Miocene bituminous rocks of the Lower Dysodilic Shale Formation and the Upper Dysodilic Shale Formation (Eastern Carpathians) has allowed recovery of pollen and spore assemblages associated with marine palynofossils (dinoflagellates and prasinophyte algae) and phytoclasts. The general composition of the assemblages suggests an anoxic depositional environment from a distal

The evolution of the Sarmatian palaeoclimate in North-Eastern Romania:A palaeobotanical approach

In the present paper, 24 palaeobotanical assemblages were analysed and, by applying the Coexistence Approach method, the MAT (Mean Annual Temperature), MAP (Mean Annual Precipitations), CMT (Coldest Month Mean Temperature) and WMT (Warmest Month Mean Temperature) were calculated for the Sarmatian deposits from the north-east of Romania. The values calculated for the climatic parameters were used to obtain palaeoclimatic maps with their distribution

PALAEOCLIMATIC ESTIMATION FROM MIOCENE OF ROMANIA, BASED ON PALYNOLOGICAL DATA

Few climatic parameters available for the stratigraphic interval between Aquitanian – Pontian from Romania, have been obtained after analysis of the palynological associations using the Coexistence Approach. The results obtained for MAT (mean annual temperature), MAP (mean annual precipitations), WMT (mean temperature of the warmest month), CMT (mean temperature of the coldest month), have been synthesised and palaeoclimatic diagrams have been

Micropaleontological content of Sarmatian from southern Moldavian Platform – backbulge depozone

The southern part of the Moldavian Platform has developed under complex conditions, partially similar with the northern part, in a marine environment corresponding to the last stage of evolution of the Eastern Carpathians foreland basin with an obvious tectonic control. In Stăniţa-Vlădnicele borehole were identified microfauna taxa such as: Cycloforina karreri, Elphidium macellum, E. minutum, E. punctatum, E. crispum, E. aculeatum, E. reginum

Palaeoclimatic and palaeoenvironmental interpretation for the Sarmatian deposits of Şupanu Formation from Comăneşti Basin (Bacău County)

This paper describes and interpretes a Sarmatian palaeoflora identified within Şupanu Formation. This formation was intercepted in 2 outcrops: one located in Asău cuvette and the other one in Lăloaia-Galeon cuvette. Based on palaeofloristic investigations a palaeoenvironmental and palaeoclimatical reconstruction was accomplished. In the Sarmatian, Comăneşti Basin recorded an abundant plants biomass development, in a swamp environment, allowing

PALYNOFACIES AND TOTAL ORGANIC CARBON CONTENT FROM THE BAIA BOREHOLE (MOLDAVIAN PLATFORM)

The studied borehole is located near the city of Falticeni, in the western part of the Moldavian Platform. The lithology consists of sands/sandstone, claystone and shale. In the present study, for the interpretation of the palynofacies, 16 samples from the Baia borehole, collected at depths between 290 and 1050 m, have been analyzed. For the analysis of the Total Organic Carbon (TOC), 10 samples were prepared and analyzed. For most of the samples,

PALYNOLOGICAL STUDY OF THE VOLHYNIAN DEPOSITS FROM THE CIOFOAIA BROOK (MOLDAVIAN PLATFORM) – PALAEOCLIMATIC AND PALAEOENVIRONMENTAL IMPLICATIONS

The study area is located 10 km east of the city of Falticeni (Suceava County), in the Preutesti village. According to Tibuleac (1998), the age of the deposits from the Ciofoaia brook is Volhynian. 12 samples were collected from the outcrop, out of which 4 were used for palynological investigations. In order to reconstruct the palaeoclimate based on the palynological record, the “Coexistence Approach” (CA) (Mosbrugger and Utescher, 1997) method

Paleofloristic study of the Volhynian from Tiganca River (Moldavian Platforme) Paleoclimatic and paleoenvironmental implications
Paleofloristic study of the Sarmatian deposits from Rasca Valley (Moldavian Platform)

The main purpose of this PhD thesis was to achieve a paleofloristic study of the Rasca Valley area. For this study was used paleofloristic (palynological and macrofloristic) samples from outcrops in Rasca (Suceava county) and from a drilled boreholes around Baia village. We also attempted to determine the values of MAT (mean annual temperature) and MAP (mean annual precipitation) using coexistence approach method (proposed by Mosbrugger and Utescher
