%X Seventy-three species of 21 different diatom genera were identified from three stratigraphic sections which are located in the late Miocene-early Pliocene volcanosedimentary units in Tahar and G¨¹zel£¿z (Nev£¿ehir) areas. One of these sections was measured in the Tahar area (in the late Miocene age Bayramhac£¿l£¿ Member of ¨¹rg¨¹p Formation), and the two sections were measured in the G¨¹zel£¿z area (early Pliocene age K£¿£¿lada£¿ Member of ¨¹rg¨¹p Formation). When evaluated of the investigated area diatomite¡¯s palaeoecological properties by considering the distribution of numerical values (in 20 microscopic slide area) of the determined diatom genus and species; It have been determined that, when the formation of the diatomite at all three locations, the lake water has neutral and acid properties. At the Tahar and G¨¹zel£¿z-2 locations the lake water was fresh water feature, also, in the G¨¹zel£¿z-1 location the lake water was initially as fresh water feature and than changed to bitter water character towards to top of the section. At the Tahar location (late Miocene); lake water¡¯s level and temperature was high, the bottom of the lake was muddy. The nutrient ratio of lake water was initially low-moderate, later increased towards to top of the section. Lake water's oxygen ratio was initially high, later in the middle level. At the G¨¹zel£¿z¨C1 location (early Pliocene); lake water¡¯s level and nutrient was variable. There were plants at the bottom of the lake. Lake water's oxygen ratio was initially high, later in the middle level. The lake water¡¯s temperature ratio was initially low, later increased towards to top of the section. Also, lake water's oxygen ratio was initially high, later in the middle level. At the G¨¹zel£¿z-2 location; lake water¡¯s level, temperature and nutrient was high
