- Abstract:
- ... Unweathered overburden shale was continuously leached with water and sulfuric acid solutions (10⁻³ and 10⁻²N) for periods of up to 3 months. Clay samples from the shale were also subjected to artificial weathering by incubation in sulfuric acid solutions. Acidity resulted in increased leaching of the basic cations from the exchange complex, particularly Ca and Mg, and a decrease in percent base sa ...

- Abstract:
- ... The Aubrey soil occurs in the East Cross Timbers Region of north-central Texas. It has developed in an acid clayey shale of the Lewisville member of the Woodbine geologic formation of Upper Cretaceous age. Jarosite [KFe₃(OH)₆(SO₄)₂] occurs in localized concentrations in the lower horizons. Selected particles form the C horizon were 87.6% jarosite and served as a reference mineral for the soil. Jar ...

- Abstract:
- ... Corrosion of steel specimens was monitored in 15 Texas soils in order to test the current system for assessing soil corrosivity. Corrosion, measured in situ at two depths using electrical resistance probes, was a function of many soil properties and could not be adequately described using any single property. The current system, developed by the USDA-SCS, which places soils into corrosion potentia ...

- acidity; calcium chloride; catalysts; copper; grinding; hydrogen peroxide; iron; leaching; mine spoil; oxidation; pyrite; sediments; surface mining; titration; Texas
- Abstract:
- ... Acidity that develops in mine spoil after exposure to the environment commonly results from oxidation of iron disulfides, mainly the minerals pyrite and marcasite. It is often necessary to quantify the acid-producing potential of overburden sediments prior to surface mining or during the reclamation process. To prevent excessive acidity problems from occurring on the spoil surface, or to correct a ...

- Abstract:
- ... Alfalfa (Medicago sativa L.) is rarely grown on the Coastal Plain of southern United States. Production problems include infertile acid soils, inadequate pest control, and high humidity with frequent rainfall events that preclude adequate alfalfa hay drying conditions in spring. Research to overcome soil fertility problems included evaluation of nitrogen (N) rates over alfalfa row spacings and lim ...

- Abstract:
- ... Siderite (FeCO₃) is commonly found in coal overburden and, when present, can cause interference in the determination of neutralization potential (NP). Under acidic testing conditions, FeCO₃ reacts to neutralize acid, which contributes to the NP. However, continued weathering of FeCO₃ (oxidation of Fe²⁺ and hydrolysis of Fe³⁺) produces a neutral to slightly acidic solution. The effects of hydrogen ...

- Abstract:
- ... Citrus tristeza virus (CTV) is one of the most devastating disease in areas where sweet orange or grapefruit are budded onto sour orange rootstock. In Texas, the citrus industry is located in the far south of the state in a high pH and calcareous soils region, which makes sour orange the best rootstock option. The Texas industry has been under a threat since the arrival in Florida and Mexico of th ...

- Abstract:
- ... We directly measured the partial pressure of dissolved CO₂ (pCO₂) in two humid subtropical rivers in coastal Texas, one highly urbanized (Buffalo Bayou) and one relatively undeveloped (Spring Creek), and analyzed carbon isotopic signatures (Δ¹⁴C and δ ¹³C) of riverine dissolved inorganic carbon (DIC) to determine carbon sources sustaining river respiration. Both rivers were highly supersaturated w ...

- Abstract:
- ... Principal component analysis has been applied for source identification and to assess factors affecting concentration variations. In particular, this study utilizes principal component analysis (PCA) to understand groundwater geochemical characteristics in the central and southern portions of the Gulf Coast aquifer in Texas. PCA, along with exploratory data analysis and correlation analysis is app ...

Experiments were carried out at 100 bar pressure and 60 or 150 °C in 0.7 m NaCl brine to characterize the reactivity of two Frio quartzofeldspathic sandstone compositions and to elucidate the fate of metals (Ba, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in subsurface reservoirs targeted for carbon dioxide sequestration and storage. The solutions were either acidic (pH ~3) or near-neutral (pH ~8). In the form ...

Framework-forming scleractinian (FFS) corals provide structurally complex habitats to support abundant and diverse benthic communities but are vulnerable to environmental changes and anthropogenic disturbances. Scientific modeling of suitable habitat provides important insights into the impact of the environmental conditions and fills the gap in the knowledge on habitat suitability. This study pre ...
