Abstract
The present study represents an attempt at highlighting the palynological assemblage identified at the level of the Sarmatian deposits intercepted by the drilling from the Bilca–Frătăuţii Noi area (Moldavian Platform). The palynological results have been interpreted in order to establish the palaeoclimatic conditions during the sedimentation of the studied deposits. Within the drilling in question, we have identified taxa such as the following: Pityosporites microalatus, Pityosporites alatus, Pityosporites labdacus, Pinuspollenites miocaenicus, Abiespollenites latisacatus, Monocolpopollenites tranquillus, Tricolpopollenites liblarensis, Engelhardtioidites microcoryphaeus, Leiotriletes sp. a. o. The method applied so as to estimate the values of the climatic parameters is the “Coexistence Approach,” designed by Mosbrugger and Utescher (1997), a method that has been frequently used for the reconstruction of the palaeoclimate from the European Tertiary. The values obtained using this method for the Sarmatian deposits intercepted by the Bilca–Frătăuţii Noi borehole are as follows: Mean annual temperature (MAT) 16.5–18.4°C, Mean annual precipitation (MAP) 887–1281 mm/yr, Mean temperature of the coldest month (CMT) 9.6–133°C, and Mean temperature of the warmest month (WMT) 27.3–28.1°C.

Geochemical and hydrodynamic control of trace element transport in a reservoir: impact of interflow layer
Concentration of trace elements both in the water column (dissolved phase and acid-soluble suspended particles) and in sediments (bulk and acid-soluble particles) was followed for one year in a water reservoir (the Bic...
The geochemical distribution of the heavy metals in the forestlands of the moor Şaru Dornei
Industrial activities such as burning coal and gasoline are the main factors which contribute to the more increasing emissions of heavy metals in the atmosphere. Once they have reached the atmosphere, these are easily di...
Early Cretaceous duvaliids (Belemnitida: Mollusca) of the Rarău Syncline (Eastern Carpathians, Romania)
The present paper focuses on the Early Cretaceous duvaliids of the Rarău Syncline, including the recently-sampled specimens from the grey marly matrix of the so-called “Gura Sadovei Breccia” and the previously-described...
Sarmatian (Middle Miocene) Coastal Deposits in the Wedge-Top Depozone of the Eastern Carpathian Foreland Basin System. A Case Study
The deposits studied crop out in the Piemontan Hills south of the Vicovu de Jos village (Suceava County). For the first time, the sedimentological characteristics of these deposits (mainly sands with minor interlayers of...
