After examined, most of the semi-subterrane houses were used as the workshops for sorting the jade materials, and they were mostly distributed in groups, with rectangular plane, single or suite. Workshops consist of post holes, gateway, storage pits, earth-platforms, operating platforms, hearths, etc. Different types of whetstones, jade pieces, stone shards and other materials were left on the ground, and fire burned traces can be seen obviously on part of the floor, with ashes left. Through excavations, a number of workshops with clear stratigraphic relationship were found, gaining the relations of broken and overlapped between different groups of houses, finding out the phenomenon that many houses were reused after reconstruction.

Mazongshan Jade Mine Site is the largest early-found mine remains in the northwest, currently. It directly demonstrates the settlement patterns of the mining district at that time, providing important materials for us to understand the technology and methods of mining and sorting; the living conditions; industrial management, social organization and etc, offering important clues for exploring the sources of the jade materials in ancient China.    (Translator: Wang Jue)
