Archeaological, Geological and Genealogical Indications of Ancient Chronology

As has been emphasized earlier, it is very important to check the approximate consistency of the astronomically derived chronology with other available information from different sources. In this respect, there are three major sources which can indicate the antiquity of the ancient chronology of protohistoric India. These are (i) geological and climatological, (ii) archaeological and (iii) genealogical evidences.
