Prehistoric Korea

The Prehistoric Korea is the era of human existence in the Korean Peninsula for which written records did not exist. It, however, constitutes the greatest segment of the Korean past and is the major object of study in the disciplines of archaeology, geology, and palaeontology.

Geological prehistory is the most ancient part of Korea's past. The oldest rocks in Korea date to the Precambrian. The Yeoncheon System corresponds to the Precambrian and is distributed around Seoul extending out to Yeoncheon-gun in a northeasterly direction. It is divided into upper and lower parts and is composed of biotite-quartz-feldspar schist, marble, lime-silicate, quartzite, graphite schist, mica-quartz-feldspar schist, mica schist, quartzite, augen gneiss, and garnet-bearing granitic gneiss. The Korean Peninsula had an active geological prehistory through the Mesozoic, when many mountain ranges were formed, and slowly became more stable in the Cenozoic. Major Mesozoic formations include the Gyeongsang Supergroup, a series of geological episodes in which biotite granites, shales, sandstones, conglomerates andesite, basalt, rhyolite, and tuff that were laid down over most of present-day Gyeongsang-do Province.

The remainder of this article describes the human prehistory of the Korean Peninsula.

Historians in Korea use the Three-age system to classify Korean prehistory. The three age system was applied during the post-Imperial Japanese colonization period as a way to refute the claims of Imperial Japanese colonial archaeologists who insisted that, unlike Japan, Korea had "no Bronze Age".

There are some problems with the three-age-system applied to the situation in Korea. This terminology was created for the situation in prehistoric Europe, where sedentism, pottery and agriculture go together to characterize the Neolithic stage. The periodization scheme used by Korean archaeologists proposes that the Neolithic began in 8000 BCE and lasted until 1500 BCE. This is despite the fact that palaeoethnobotanical studies indicate that the first bona fide cultivation did not begin until circa 3500 BCE. The period of 8000 to 3500 BCE corresponds to the Mesolithic cultural stage, dominated by hunting and gathering of both terrestrial and marine resources.
