ABSTRACT

Limited excavations at Nangara-Komba Shelter along the northern margin of the Congo Basin have recovered evidence for intermittent and at times intensive human visits beginning approximately 5100 cal. BC. Numerous rock art panels adorn the shelter’s walls and ceramics appear to have initially been brought to the site between 1050 and 900 cal. BC, if not earlier. Charred Canarium schweinfurthii endocarp fragments were collected in all stratigraphic aggregates and reflect the use of canarium for food, fuel and/or medicinal purposes during the middle and late Holocene. Abundant quartz and quartzite artefacts occur throughout the deposits and mark a continuous and stable microlithic tradition. The site was used only by foraging groups who ultimately interacted with Bantu and later Ubangian farmers and possibly smelters. Nangara-Komba represents a sheltered context where the use of lithic tools appears to have persisted well into the late Holocene and is the only known site in the Central African Republic and Sangha River Interval with episodic occupations spanning the past 7000 years.

摘要

在刚果盆地北缘的Nangara-Komba住房进行了有限的挖掘，已发现断断续续的证据，有时密集的人类探视开始于大约5100 cal。公元前。避难所的墙壁装饰着众多的岩石艺术面板，最初似乎是在1050到900 cal之间将陶瓷带到现场的。公元前，如果不是更早。烧焦的施纳福斯在全新世中期和晚期，内果皮碎片被收集在所有地层聚集体中，反映出卡纳兰在食物，燃料和/或药物用途方面的用途。整个沉积物中都出现大量的石英和石英岩伪迹，这标志着连续稳定的微石器时代。该站点仅由最终与班图人以及后来的乌邦农民和冶炼厂互动的觅食组织使用。Nangara-Komba代表了一个被庇护的环境，其中石器工具的使用似乎一直持续到全新世晚期，并且是中非共和国和Sangha River Interval中唯一已知的站点，过去的7000年间存在偶发性占领。
