摘要

本研究的重点是确定两个考古遗址在占领期间可能的环境变化和植物可用性:位于哥伦比亚萨巴纳德波哥大的特昆达马和阿瓜苏克。这些遗址代表了全新世早期到中期的占领时期,为占领该地区的狩猎采集者提供了宝贵的信息。在发掘过程中获得的数据和恢复的考古材料揭示了直到全新世晚期相对连续的职业。石器制品、人类和动物骨骼遗骸的存在为理解这些人类群体之间的社会动态提供了相关信息;同样,对沉积物和动物进行了植物岩和稳定同位素分析,以确定环境变化,以及这些考古背景下植物遗骸的存在。沉积物碳同位素分析表明,C3植物在全新世早期普遍存在。反过来,从两个地点发现的哺乳动物牙釉质中获得的碳同位素关系表明,这些动物食用了这类植物。此外,牙釉质中氧的同位素值显示,这两个地方的环境都很潮湿,可能很冷。此外,植物岩分析提供了在特定环境中可用植物类型的证据,并重建了环境、用途和可用性。这三种类型的分析被应用于考古背景,以确定遗址中可用的C3或C4类型植物的存在,这使得环境变化,潮湿条件,以及在少数情况下,跨越职业的干旱,以及某些类型植物在年代期间存在或不存在的差异成为证据。表明阿瓜苏克考古遗址全新世中期的园艺过程与驯化可能存在关联。

Environmental variation in the early and middle Holocene Tequendama and Aguazuque archaeological sites, Colombia
This study focuses on identifying possible environmental variations and plant availability during the occupation in two archaeological sites: Tequendama and Aguazuque, located in Sabana de Bogotá, Colombia. Those sites represent periods of occupation during the early to middle Holocene that contributes valuable information about hunter-gatherers who occupied this area. Data obtained and recovered archaeological material during excavations shed light on relatively continuous occupations until the late Holocene. The presence of lithic artefacts, human and fauna bone remains offered relevant information to comprehend social dynamics among these human groups; likewise, phytolith and stable isotope analysis on sediments and fauna were carried out to identify environmental variations, and the presence of plant remains in these archaeological contexts. Carbon isotope analysis in sediments indicated the prevalence of plants C3 from the early Holocene. In turn, isotopic relationships in carbon obtained from mammals’ dental enamel found in both sites suggest that those animals consumed such types of plants. Also, isotopic values in oxygen from dental enamel show humid and possibly cold environmental conditions in both locations. Also, phytolith analyses provide evidence on the types of plants available in determined contexts and reconstruct environments, use, and availability. Those three types of analysis were applied to archaeological contexts to determine the presence of plants type C3 or C4 available in the sites, which permitted to evidence of environmental changes, humid conditions, and, in a few cases, drought across occupation, as well as the differences in terms of the presence or absence of certain types of plants during chronological periods, suggesting a possible association of horticultural processes and domestication during middle Holocene in Aguazuque archaeological site.

期刊介绍: The Boletín de la Sociedad Geológica Mexicana is a completely free-access electronic journal published semi-annually that publishes papers and technical notes with its main objective to contribute to an understanding of the geology of Mexico, of its neighbor areas, and of geologically similar areas anywhere on Earth’s crust. Geology has no boundaries so we may publish papers on any area of knowledge that is interesting to our readers. We also favor the publication of papers on relatively unfamiliar subjects and objectives in mainstream journals, e.g., papers devoted to new methodologies or their improvement, and areas of knowledge that in the past had relatively little attention paid them in Mexican journals, such as urban geology, water management, environmental geology, and ore deposits, among others. Mexico is a land of volcanos, earthquakes, vast resources in minerals and petroleum, and a shortage of water. Consequently, these topics should certainly be of major interest to our readers, our Society, and society in general. Furthermore, the Boletín has been published since 1904; that makes it one of the oldest scientific journals currently active in Mexico and, most notably, its entire contents, from the first issue on, are available online.
