In 2016,the School of Archaeology and Museology,Sichuan University,along with the Qinghai Provincial Institute of Cultural Relics and Archaeology,conducted excavations in Area Ⅳ3 of the Lajia site.Two houses and nine midden pits,as well as over 100 artifacts made of pottery,bone,stone,and jade,were uncovered.Amongst them,one house(F63)with secondary use traces was discovered,a cave dwelling repurposed as a semi-subterranean structure.In the lower-level cave dwelling,well-preserved architectural features such as a walled fireplace,wall niches,lamp niches,a hearth,and an object pit were found.In the upper semi-subterranean structure,many exquisite artifacts were unearthed.This discovery provides valuable data for studying house structures and artifact assemblages during the Qijia culture period and contributes significantly to understanding of the cultural significance of the Lajia site.
