POLLEN ANALYSIS AT THE ADMIRALTY SITE (CA-LAN-47), CALIFORNIA

The Admiralty Site is an urban site located near Marina del Rey in West
Los Angeles, California. The excavated portion of this site consists pri
marily of a midden approximately 60 cm in depth. The midden includes dark
A-horizons that contain food, shell, fire-cracked rock, lithics, as well as
small quantities of faunal material and shell beads. No stratigraphic
components or-features were noted at the site. Stratigraphic samples were
collected from three test pits within the midden. The pollen record ad
dresses subsistence and to identify elements of the vegetation communities
at the time of occupation, and hence interpret past environmental condi
tions. Radiocarbon dates of humates indicate that the site was occupied
between 500 and 1100 AD.

海军部遗址（Admiralty Site）是一处位于美国加利福尼亚州洛杉矶西部玛丽安德尔湾附近的城市考古遗址。该遗址的已发掘区域主要为一处厚度约60厘米的贝丘堆积。该贝丘包含深色A层（A-horizons），其内出土有食物遗存、贝壳、火烧岩、石器，以及少量动物群遗存与贝壳串珠。该遗址未发现地层单元或考古遗迹。研究人员从贝丘内的3个探方中采集了地层样品。孢粉记录旨在探讨遗址先民的生业模式，辨识当时的植被群落组成，进而阐释彼时的古环境状况。腐殖酸盐的碳十四测年结果显示，该遗址的人类活动年代为公元500年至1100年之间。
