Preliminary results 1. Fieldwork survey As a result of these researches, performed on transects  oriented West - East, in the area of Balta Ialomiţei, it was  identified archaeological inventory in 5 different areas, attributed  chronologically to Iron Age, Middle ages and, possibly, Roman  period.   2. Archaeological sondage In the field campaign 2012, it was performed the  archaeological sondage S I East, with the aim of recording and  analyzing of the overall anthropic sequence of the tell settlement  Borduşani Popină. The archaeological inventory was collected  and examined by the microstratigraphic method, being culturally  assigned, on the basis of relative chronology.  On the southern profile of the section, 16  micromorphological samples were taken, 12 bulk samples for  sedimentological and chemical analysis, and 8 samples (of which 7  bones and one wood fragment) for radiocarbon dating.   Preliminary results  - stratigraphic recording, in order to analyze in detail a  delimiting structure of the settlement, attributed to the Iron Age  (La Tène) occupation;  - analyzing the complete Chalcolithic sequence and  preliminary dating of the chrono-cultural levels (Boian and  Gumelniţa);  - systematic sampling of the stratigraphic profile. 
3. Sedimentological coring In the campaign of 2012, were conducted 18 deep  sedimentological corings, using a mechanical percussion system,  generally at a depth of 10 meters. Five of these were made in  order to ensure a continuous sampling, in undisturbed column,  necessary firstly for micromorphological and palynological  analyzes.  Bulk samples were taken from each sedimentary unit, for  grainsize, chemistry and mineralogy analyzes. A total of 100  samples were analyzed for particle size by laser method and  measured for magnetic susceptibility. In addition, 12 samples of  clay mineralogy were analyzed by X-ray diffraction. Were taken  over 100 palynological samples that are prepared to be analyzed.  Also, there have been carried out 2.5 meters deep small  corings, with a soil auger, in three different situations:  - areas likely to correspond to temporary or seasonal  habitation, where they were discovered archaeologic materials by  fieldwork researches;  - areas likely to correspond to temporary or seasonal  occupations, given the local geomorphologic conditions (higher  areas, in the proximity of water resources);  - zone assumed that would have been an access way in  the Roman period ("snails road").  Preliminary results  - identifying erosion remnants (the island in Bentul Mare  lake) of lacustrine sedimentary areas (Japșa located in the eastern  proximity of Popina, Sâltava area), some important alluvial  sedimentation areas (island in Bentul Mic lake, Ostrovul Borcea);  - absence of habitation in this area, although presumed;  - systematic sampling for sedimentological and  palynological analyses and radiocarbon dating.
