WebJul 29, 2024 · A pH value above 7.0 indicates that the soil is alkaline (basic), with higher values representing increasing alkalinity. The pH scale is logarithmic, so a change in 1 pH unit reflects a 10 fold change in acidity or alkalinity. On average, garden and landscape plants grow best in soils with pH values between 6.0 and 7.2. Causes of Soil Acidity

A typical shale is composed of about 58% clay minerals, 28% quartz, 6% feldspar, 5% carbonate minerals, and 2% iron oxides. [8] Most of the quartz is detrital (part of the original sediments that formed the shale) rather than authigenic (crystallized within the shale after deposition). [9] See more Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2Si2O5(OH)4) and tiny fragments (silt-sized particles) of other minerals, … See more Shales are typically gray in color and are composed of clay minerals and quartz grains. The addition of variable amounts of minor constituents alters the color of the rock. Red, brown and green colors are indicative of ferric oxide (hematite – reds), iron hydroxide See more Shale is the most common source rock for hydrocarbons (natural gas and petroleum). The lack of coarse sediments in most shale beds reflects the absence of strong currents in the waters of the depositional basin. These might have oxygenated the waters and … See more • Bakken Formation – Geological rock formation known for crude oil production • Barnett Shale – Geological formation in Texas, United States See more Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often … See more The fine particles that compose shale can remain suspended in water long after the larger particles of sand have been deposited. As a result, shales are typically deposited in very slow moving water and are often found in lakes and lagoonal deposits, in See more Before the mid-19th century, the terms slate, shale and schist were not sharply distinguished. In the context of underground coal mining, shale was frequently referred to as slate well into the 20th century.

The Pr/Ph values decrease with increasing gammacerane/C 30 hopane (G/C 30 H), suggesting that the low Pr/Ph seem to be influenced by salinity (Fig. 11 b).
