Pyritic shale.

Spatial and non-spatial statistical modeling was used to infer co-localized element effects on As binding within soils developed under different pedogenic environments. We hypothesized that spatial patterns of As accumulation in relation to those of matrix elements will uniquely depend on the pedogenic environment.quantities of pyritic shale in large columns. The rationale of this approach was to determine the oxygen dependency of pyrite oxidation in the simplest case ...Expansive pyritic shales are found in black carbonaceous shales throughout the United States as well as in other countries, including Ireland, England, Norway, Canada, and Sweden.The H.Y.C. Pyritic Shale Member of the Barney Creek Formation (ca 1 500 my old; northern Australia) contains several stratiform base metal sulfide deposits of economic significance. Black cherts within these mineral deposits preserve a diverse assemblage of bacterial and algal microfossils. The assemblage differs from most other …

As recognized by Lineback, the formation consists of five members in southeastern Indiana. In ascending order they are: (1) the Blocher ...zones of reactive shale. The Sulfur Dioxide Task Group was established in order to apply the understanding of the investigations and research. This multi-disciplinary group developed the Pyritic Black Shale Procedures, which continue to be updated and are a critical part of the successful management of reactive shale at Mt Whaleback.

Organic-rich mudstones are hydrocarbon source rocks. In the last several years, a lot of fundamental and applied research has taken place on mudstones due to shale oil and gas boom in North America (Schieber, 1994; Bohacs et al., 2005; Hickey and Henk, 2007; Loucks and Ruppel, 2007; Passey et al., 2010; Abouelresh and Slatt, 2007; Hamlin and Baumgardner, 2012; Gale et al., 2014 ...It should be applied in adjective form as "micaceous," "chloritic," "glauconitic," and "pyritic." The most common cement terms are given in the chart with the root names. Some typical rock names are "black thin-bedded micaceous shale," "gray massive, medium-grained glauconitic quartz sandstone," "tan siliceous quartz pebble conglomerate," and ... The selenium content of the volcanic tuff is 26.6–48 mg/kg and of the pyritic carbonaceous slate is about 13–42 mg/kg, mostly averaging about 20 mg/kg. On the south side of valley occurs gray-green silty shale and limestone of the Jianzhuba Formation (Early Cambrian), the selenium content here is not high (Table 1, bed 6).The host succession includes carbonaceous, pyritic shales (pelites) which were a source of trace elements, including gold and tellurium.

(c) Bituminous shale: a finely laminated sediment with pyritic calcareous concretions, little or no bioturbation, and a benthic fauna which is sparse and entirely epifaunal. Heaving of floor slabs and lightly loaded structures built on black pyritic shales is a construction engineering problem in many locations, including Norway, the United States, and Canada (Quigley, etal., 1973). The cause of the heave has been documented by many workers, including Grattan-Bellew and Eden (1975); Penner, Gillott, and Eden (1970 ...Aug 1, 2002 · The distribution and oxidation state of arsenic (As) and selenium (Se) were also determined. The soil used in this study was formed from pyritic shale parent materials on the east side of the California Coast Range. Synchrotron-based X-ray fluorescence microprobe (μ-XRF) was used to generate elemental distribution maps of soil thin sections. Here, the pyritic shale occurs as a 0.78 m-thick stratiform horizon within the carbonaceous shales extending over an area of 2.1 km 2. The uniform thickness as well as the conformable nature of the pyrite bed with the overlying and underlying carbonaceous shale is a conspicuous feature throughout.

Using shale gas to replace traditional energy is crucial for the energy structure up-grada-tion and carbon emission reduction (Tao and Clar-ens 2013; Zou et al. 2021). As a result, shale gas hasshale. Pyrite is present in many varieties of metamorphic, sedimentary, and igneous rocks, and expansion due to the weathering of pyrite in several rock types (e.g., shale, gneiss, schist) has been documented.
