江西沟2号遗址(JXG2)发现于2004年,2012年围绕地层测年及环境研究开展了小面积试掘。本文通过对2012年出土的669件石制品进行的观察和初步研究,并结合其他出土遗物及考古年代学研究的基本结论,对遗址所反映的史前人类行为的变化及其与环境的关系作了初步报告。根据出土文化遗物(主要指石制品和陶片)的差异,遗址可以分为上下两个文化层,上文化层为10~80cm,包含陶片和细石器为主的石制品;下文化层为距地表80cm以下的堆积,该层仅包含石制品,其中除以燧石为原料的细石器产品,同时出土石英砸击产品。光释光和AMS14C年代测定结果表明古人类在该遗址活动的时间主要集中在全新世中期,遗址石制品原料和技术变化的研究初步揭示了该时段区域内史前人类的行为变化和生活方式的转变。
Site 2 (JXG2) was discovered in 2004 and a small area test was conducted in 2012 around the dating of stratigraphy and environmental studies. Based on the observation and preliminary study of 669 stone products unearthed in 2012 and the basic conclusions of other unearthed relics and archaeological chronology, this paper makes a survey on the changes of the prehistoric human behaviors reflected in the sites and their relationship with the environment Preliminary report. According to the unearthed cultural relics (mainly stone products and pottery) differences, the site can be divided into two upper and lower cultural layers, the cultural layer is 10 ~ 80cm, including stone pieces and fine stone-based stone products; under the cultural layer 80cm below the surface of the accumulation of the layer, which contains only stone products, which divided by flint as a raw material of fine stone products, while unearthed quartz hit the product. Photoluminescence and AMS14C dating results show that the time of the ancient human activities in the site mainly concentrated in the mid-Holocene, the study of the changes of raw materials and technology of stone products in the ruins revealed the prehistoric human behavior change and lifestyle change .
