Abstract: Three main types of continental sediments of Late Pleistocene can be recognized in North China: the cave deposits, the alluvial-lacustrine deposits and loess. More than two hundred mammalian fossil localities of Late Pleistocene and Late Paleolithic Sites have been investigated and excavated in recent years. The occurrence of Late Paleolithic Sites and mammalian fossils of Late Pleistocene seem to be corresponded to the stratigraphy, lithology, geomorphology and taphonomy. Artifacts and fossils are often discovered in:
(1) the middle or lower part of the second terrace of local river and its tributaries;
(2) the orangish sand-gravel and blackish sandy day of alluvial-lacustrine deposits;
(3) the bottom of gravel under the Malan loess in the loess plateau;
(4) the piedmont of hill which stretches into the alluvial basin or plain.
