Analyses of magnetic susceptibility, carbon content, pollen assemblages and macrofossil data in a 15 m thick sediment sequence provide the first continuous record of Lateglacial and Holocene vegetation history in Sudetes region of the Czech Republic.
Based on the magnesium, potassium and aluminium oxide contents the assemblage can be divided into at least three distinct groups (Fig. 1a&b).
Recurring relationships between artifact density and assemblage content at Middle and Upper Paleolithic sites reflect simple behavioral dynamics pertaining to artifact production and discard.
While animals may colonize the new surface in less than a week, and tubes are also quickly produced (Alvinella species may grow their tube up to 1 cm day−1 during the early stages of colonization), mineral precipitation progressively increases the mineral content of the assemblage.
Metagenomics is the study of the genomic content of a assemblage of organisms, obtained from a common habitat or an environmental sample of microbes.
The results show that biogenic structure in the form of live mussels and mussel shell hash is important in this system, as is terrestrial gravel, and that these variables are more important than silt-clay content for the macrofaunal assemblage.
Not content to tell the assemblage to change the world and smell the roses, she polled the student body, solicited ideas and poems, beautifully captured the turmoil and hope of the times, got a standing ovation, and her speech was featured in Life Magazine.
Pollen, aquatic microfossils, and charcoal, as well as previously published data including diatom assemblages, carbonate content, and stable carbon isotopic ratios of organic carbon, indicate that interglacials were warm and dry whereas the peaks of glacials were cold and wet.
The effect of the PMN contents on the phase assemblage, microstructure, dielectric and magnetic properties of the samples were investigated by X-ray diffraction (XRD), scanning electron microscope (SEM), LCR meter and vibrating sample magnetometer (VSM), respectively.
The mineral compositions of olivine (Fo69Fa31) and diopside (En48Wo42Fs10) and the high Ni content in a troilite-tetrataenite assemblage are in agreement with the classification of the Hayabusa particle as LL-type ordinary chondrite material (Nakamura et al. 2011, 2012; Tsuchiyama 2014).
