Abstract

The important albeit discontinuous pollen and more complete small mammal microrecords from the long, Late Upper Pleistocene stratigraphic deposit in El Mirón Cave (Cantabria, Spain, >47,000–12,000 cal BP) are presented and compared in detail. They describe a sequence of environmental conditions varying from cold and relatively dry to somewhat more temperate and more humid throughout the course of late MIS 3 and MIS 2, and into the early Holocene conditions of MIS 1, with variable intensity and function of human occupation of the cave during late Mousterian, Gravettian, Solutrean, Magdalenian and Azilian cultural periods. In general, the discontinuous palynological record is concordant with the more continuous small mammal sequence in tracing the changes in local climate and landscape within the broader context of the high relief and coastal setting of the Cantabrian region of northern Atlantic Iberia. Shifts in the extent and composition of open versus wooded vegetation in the montane and low valley surroundings of the cave are documented by the analyses detailed here. Some of the environmental fluctuations, namely the Last Glacial Maximum, the Late Glacial and the at the beginning of the Holocene, seem to have had significant effects on the nature of human uses of this cave with short, ephemeral, special/limited-function visits, while Oldest Dryas, despite its still-rigorous conditions but abundant pasture for game species (red deer and ibex), did not prevent the cave from being used as a major, repetitive, long-term base camp for foraging bands, notably during the Cantabrian Lower Magdalenian.
西班牙坎塔布里亚El Mirón洞穴更新世最后4万年花粉和小型哺乳动物光谱组成的变化以及人类与景观的关系
本文详细比较了El Mirón洞穴(Cantabria, Spain, > 47,000-12,000 cal BP)上更新世晚期地层沉积物中重要的花粉和更完整的小型哺乳动物微记录。他们描述了一系列的环境条件,从寒冷和相对干燥到更温和和更潮湿,贯穿MIS 3晚期和MIS 2的过程,以及MIS 1的全新世早期条件,在Mousterian晚期、Gravettian晚期、solutreian晚期、Magdalenian晚期和Azilian文化时期,人类对洞穴的占领强度和功能都有所不同。一般来说,在伊比利亚北部坎塔布连地区的高地形和海岸环境的更广泛背景下,不连续的孢粉记录与更连续的小型哺乳动物序列在追踪当地气候和景观变化方面是一致的。这里详细的分析记录了洞穴周围的山地和低山谷中开放植被与树木植被的范围和组成的变化。一些环境波动,即末次盛冰期、晚冰期和全新世初期,似乎对人类使用该洞穴的性质产生了重大影响,这些洞穴具有短暂、短暂、特殊/有限功能的访问,而最古老的仙女木时期,尽管条件仍然严格,但有丰富的狩猎物种(马鹿和野山羊)牧场,并没有阻止洞穴被用作主要的、重复的、长期的觅食营地。特别是在坎塔布里亚下马格达莱尼亚时期。

期刊介绍: Quaternary International is the official journal of the International Union for Quaternary Research. The objectives are to publish a high quality scientific journal under the auspices of the premier Quaternary association that reflects the interdisciplinary nature of INQUA and records recent advances in Quaternary science that appeal to a wide audience. This series will encompass all the full spectrum of the physical and natural sciences that are commonly employed in solving Quaternary problems. The policy is to publish peer refereed collected research papers from symposia, workshops and meetings sponsored by INQUA. In addition, other organizations may request publication of their collected works pertaining to the Quaternary.
