Chemical and mineralogical characteristics of peloids in Turkey

Environmental Monitoring and Assessment, 2020
To investigate the physical, chemical, and mineralogical characteristics of peloids, which are being used traditionally and historically across Turkey, and evaluate their suitability and potential for use in peloidotherapy. Five peloid samples were gathered from their places of origin, namely Gölemezli, Dalyan, Köprüköy, Gökçeada, and Dikili.

The mineralogical characteristics of calcium-iron olivines

Mineralogical Magazine and Journal of the Mineralogical Society, 1968
SummaryFor the estimation of the properties of calcium-iron olivines in ironore sinters, synthetic mixtures of CaO, FeO, and SiO2 were prepared and melted; the obtained olivines were then examined microscopically and by X-ray powder method. The investigations allowed to state, that with the increase of the basicity of sinters, the relation of Fe : Ca ...

Petrographic and Mineralogic Characteristics of Aggregates

1948
The petrographic and mineralogic characteristics and geologic occurrence of rock formations and sand and gravel deposits determine the composition, gradation, and quality of aggregates. Thus, because of their several modes of origin—igneous, sedimentary, and metamorphic—rock formations present different problems to the quarryman and produce aggregates ...

Clay Mineralogical and Related Characteristics of Geophagic Materials

Journal of Chemical Ecology, 2003
Geophagy is the deliberate consumption of soil and clay deposits by animals, including man. Various hypotheses have been advanced to explain geophagic behavior, the main ones being: detoxification of noxious or unpalatable compounds present in the diet, alleviation of gastrointestinal upsets such as diarrhea, supplementation of mineral nutrients, and ...

Geotechnical and mineralogical characteristics of marl deposits in Jordan

Environmental Geology, 2007
Marls and marly limestone deposits cover most of Northern Jordan, where Amman City and its suburbs are located. These deposits serve as foundations for most buildings and roads as well as fill material for structural back filling, especially road bases and sub-bases.

Characteristic features of the mineralogy of uranium

The Soviet Journal of Atomic Energy, 1960
The following characteristic features of the mineralogy of uraniun are discussed in the article: 1) all known uranium and uranium-bearing minerals contain oxygen; 2) uranium in minerals is present only in the tetra- and hexavalent states; 3) the bulk of the uranium in the earth's crust is concentrated in nonuranium minerals in the form of isomorphous ...
