Chemical Weathering - an overview | ScienceDirect Topics

A.S. Trenhaile, in Reference Module in Earth Systems and Environmental Sciences, 2016 Chemical weathering. Chemical weathering is promoted on rock coasts by alternate immersion and exposure in the intertidal zone and by spray and splash in the supratidal zone (Fig. 3c) astal zones therefore provide the water that is needed for chemical reactions and the runoff to remove the soluble products.

Glossary of Geology Terms and Definitions - Science Struck

Acidic rock is a term that refers to an igneous rock, which is made up of light-colored minerals. This rock consists of more than 66% of combined or free silica. Thus, acidic rock can also be defined as an igneous rock that has maximum silica content. Some of the examples are rhyolite and granite.

Soil Formation - an overview | ScienceDirect Topics

Soil formation is a process strongly driven by the boundary conditions for the soil system. One of the key conditions (e.g., initial state in eqn [1]) is the physical configuration of the landscape, which dictates the nature of the ''geomorphic surface'': the atmosphere/land boundary om a physical perspective, landscapes can be stable, erosional, or depositional.

Mining - Wikipedia

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Silicon - Wikipedia

Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid and semiconductor is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, and lead are below it. It is relatively unreactive. Because of its high chemical affinity for oxygen, it was not ...

Brick - Wikipedia

A brick is a type of block used to build walls, pavements and other elements in masonry construction. Properly, the term brick denotes a block composed of dried clay, but is now also used informally to denote other chemically cured construction blocks icks can be joined together using mortar, adhesives or by interlocking them. Bricks are produced in numerous classes, types, materials, and ...

Pore Pressure - an overview | ScienceDirect Topics

Pore pressure prediction in claystone/shales is based on the premise that the response of sonic velocity, resistivity, and density tools are a proxy for porosity. A further assumption is that high porosity in the formations at depth is due to the inability to dewater (compact with depth). The retention of water a) preserves porosity and b) requires that the retained water must support a ...


Quartz is the main primary mineral (if originally present in the parent rock). The clay assemblage is dominated by kaolinite, goethite, hematite and gibbsite in varying amounts, in line with the kind of parent rock and the drainage conditions (see also Table 1). Hydrological characteristics

Fill slope angle for common earth (a mixture of fragmented rock and soil) should typically not exceed 33.6º which corresponds to a rise: run ratio of 1:1.5. Therefore, a road prism on side slopes steeper than 50 - 55% (26 - 29º) should be built as "full-benched" because of the marginal stability of the fill section.

Phish concert tours and festivals - Wikipedia

American rock band Phish is one of the most successful live acts in popular music history, forging a popularity in concert far greater than their album sales, radio airplay, or music video presence would otherwise indicate. Phish, at the peak of their popularity in the mid- to late 1990s, consistently ranked as one of the highest-grossing concert tours in the world.
