Mine Spoil Potentials for Soil and Water Quality

The predominating lime influence from calcareous shales and mudrocks, even beyond the recognized limestone in parts of the section, undoubtedly account for recent successful vegetative re- clamation. Increasing pH of the long acidic Elk Creek watershed is probably due in part from erosion of calcareous materials exposed during surface mining. Get price

Petrology of Sedimentary Rocks, Second Edition

As discussed in greater detail below, mudrocks (shales), sandstones, and limestones make up the bulk of all sedimentary rocks in the rock record. The compositions, textures, and structures of sandstones and limestones make them particularly important as indicators of past depositional conditions. Get price

Hydraulic, diffusion, and retention characteristics of

As shown in the table 2.1, the cation exchange capacities of montmorillonite and vermiculite minerals are the highest (in the range of 80~150 meq/100g) among all clay minerals because of their high isomor phous substitution within the octahedral and tetrahedral Get price

Sedimentary rock

Sedimentary rock - Sedimentary rock - Mudrocks: In terms of volume, mudrocks are by far the most important variety of sedimentary rock, probably constituting nearly 80 percent of the Earth's sedimentary rock column. Despite this abundance, the literature on mudrocks does not match in extent or detail that dealing with sandstones, carbonate rocks, and the various rarer sedimentary rock Get price

Diagenesis II

Mineralogy Cenozoic mudrocks consisted initially of abundant illite and mixed-layer illite/smectite (Burst, 1969; Perry and H o u e, 1970; Freed, 1981; Jackson, 1986). At burial depths between 2.5 and 4 km at a concomitant temperature of about 120C, most of the smectite has converted to illite, releasing bound water and taking up potassium. Get price

Low recovery cores are typically fractured and consist of silty and/or calcareous mudrocks, whereas full recovery cores, with no visible cracks, consist of fine-grained smectite-rich mudrocks. Mineral reactions which tend to strengthen the mudrocks, e.g. smectite diagenesis (1800 mKB), carbonate cementation and Opal CT to quartz appears to be poorly represented in the Get price
