    The thermal behavior of a woolly erionite-K sample (Lander County, NV, USA), chemical formula (Ca 2.03 Na 0.73 K 2.52 Mg 0.26)[Al 8.22 Si 27.78 O 71.80]·35.94H 2 O, was investigated in the 303–1173 K thermal range by in situ X-ray powder diffraction. Present data suggest a general thermally-induced volume contraction whose magnitude increases as S i S i + A l ratio becomes smaller.[...]

    The existence of complex red bed-evaporite sequences in the Nippewalla Group, upper Leonardian, Permian, in the subsurface of western Kansas, has been known since the late 1800s. Much progress was made in the identification of the individual units during the 1920s and 1930s as a result of numerous wells drilled in exploration for oil and gas.[...]

    Bond Work Index. In the 1930s through early 1950s, Bond developed a new theory of comminution that introduced an index, called the 'Bond Work Index', which relates power consumption in crushing and grinding to the feed and product size distribution. His theory and index were introduced in a widely cited 1952 journal article.[...]

    Natural gas is stored underground in geologic structures throughout the United States. However, complexities associated with these geologic structures may provide vertical pathways for gas migration, and thus gas loss. Possible upward migration (loss) of natural gas in an underground gas storage field in stimulated this investigation that aims to identify potential migration pathways.[...]

    Jun 12, 2018· The strata of the “Upper Member” are exclusively composed of siltstones, sandstones, and dolomitic sands, which reduces the preservation potential of calcitic shell material due to early diagenetic dissolution (Hofmann et al. 2015). In addition, the “Upper Member” is rarely well exposed, which adds another sampling bias.[...]
