Element composition of ground water and speleothem “moon milkˮ in a karst cave Proshchal’naya (Far East)

Object of research.The aim of this work was the comparative analysis of element composition of groundwater (drip, fracture), water from the interior of the watercourse in a karst cave Proshchal’naya (Khabarovsk Territory) and the surface water of the nearest river Sagdy-Selanka. The great interest was the study of speleothem (dropstones) “moon milk” in the cave Proshchal’naya.Materials and methods.Speleothem “moon milk” was investigated with a scanning electron microscope (EVO-40HV, CarlZeiss, Germany) and silicon-drift x-ray detector X-MAX 80 мм2 . By ICP-MS method a comparative analysis of element composition of groundwater (drip, fracture), water from an internal stream in the cave Proshchal’naya and surface water of the river Sagdy-Selenka were carried out.Results.Maximum concentrations of calcium, iron and manganese was installed in the spring, between drip and fracture water and magnesium – in flowing waters (inland watercourse caves and Sagdy-Selanka R.). It was determined that visually plastic and homogeneous mass of speleothem “moon milk” is heterogeneous and contains various microstructures. Tubular microstructures were represented by richer elemental compo sition (C, O, Ca, Fe, Mn, Si, Al, and S) compared with club-shaped formations (C, O, Ca, and Na). The binding matrix in the composition of the “moon milk” were reticular structures similar to actinomycente mycelium and bacterial films. Findings. The results of studies conducted in a monsoon climate may be interesting for researchers which study karst processes in other climatic zones.

Chapter one examines the formation of Asian American writers in the era of Asian exclusion through a comparative analysis of Younghill Kang’s and Carlos Bulosan’s responses to Orientalism in their works. As legal exclusion created the racial category of Asian in the United States, migrant Asian writers faced the challenge of creating modern Asian subjects in literary English. Cultural brokers between Orientalist images of their countries of origin and the modern experiences of Asian migrants in the United States, Kang and Bulosan tested the boundaries of English to represent migrant experiences lived in languages other than English. As a heterogeneous cultural epistemology, Orientalism placed different constraints on Kang, who contended with the Orientalist valorization of the Far East, and Bulosan, who resorted to the Filipino intellectual tradition of the ilustrado in the face of Orientalist primitivism.

Abstract Pyrite is a common mineral in sedimentary rocks and is the major host for many chalcophile trace elements utilized as important tracers of the evolution of the ancient hydrosphere. Measurement of trace element composition of pyrite in sedimentary rocks is challenging due to fine-grain size and intergrowth with silicate matrix and other sulfide minerals. In this contribution, we describe a method for calculation of trace element composition of sedimentary pyrite from time-resolved LA-ICP-MS data. The method involves an analysis of both pyrite and pyrite-free sediment matrix, segmentation of LA-ICP-MS spectra, normalization to total, regression analysis of dependencies between the elements, and calculation of normalized composition of the mineral. Sulfur is chosen as an explanatory variable, relative to which all regressions are calculated. The S content value used for calculation of element concentrations from the regressions is calculated from the total, eliminating the need for independent constraints. The algorithm allows efficient measurement of concentrations of multiple chalcophile trace elements in pyrite in a wide range of samples, including quantification of detection limits and uncertainties while excluding operator bias. The data suggest that the main sources of uncertainties in pyrite composition are sample heterogeneity and counting statistics for elements of low abundance. The analysis of regression data of time-resolved LA-ICP-MS measurements could provide new insights into the geochemistry of the sedimentary rocks and minerals. It allows quantification of ratios of elements that do not have reference material available (such as Hg) and provides estimates on the content of non-sulfidic Fe in the silicate matrix. Regression analysis of the mixed LA-ICP-MS signal could be a powerful technique for deconvolution of phase compositions in complex multicomponent samples.
