The Upper Paleolithic complex of Selemdja clearly shows the developing process how the technical feature of Northeast Asian microblade core was erupted and combined. This study examines the type and the sub-type of this site with a new view based on the manufacturing technique for core stones, and classifies into 6 types and 17 sub-types. On these micro-cores, many researchers in Northeast Asia tried to make the frame of the most universal technology by studying various ways to classify each type. However, the diversity of technical eruption in their studies didn't explain the technical eruption on a single site or was just theoretical. The diversity also failed to show that the technical eruption made a time arrangement in which process. Therefore, this study tries to explain the problems into three parts by re-examining the upper-mentioned each type in technical side. The three parts are (1) the bifacial technique system, (2) system of the use of the flake and (3) system of the use of blank. By this, the study can figure it out that these three systems are related with the culture patterns' changes of the Microblade Culture in Selemdja Upper Paleolithic Site. In other words, explained with a relative chronological frame, it means that firstly it had appeared to the complex technical system corresponded to bifacial system and then the use of the ventral part of flake added to the existed system. The last step of Upper Paleolithic Age seems to have used the manufacturing technique for prismatic core or conical core based on a developing technique to utilize the raw material.
