This work, originally based on a series of the authors' publications [101 , 102, 104, 112, 130, 131], considers general questions of ice-sheet flow modeling as related to ice core records interpretation. It reviews the previous results and, using new geographical, geophysical and glaciological data, continues the study aimed at solving the twofold problem of ice core age dating and paleoclimatic reconstructions from the isotopic content measurements in the deep ice cores from Vostok Station located in central East Antarctica, above the vast subglacial lake. The principal idea of the paper is to develop a general approach to past climate investigation by means of an improved thermo-mechanical ice flow line model, involving a wide spectra of supplementary data such as borehole-temperature, radio-echo-sounding reflection layers, and air-bubble measurements.
