Efforts to preserve urban monuments may benefit from an initial characterization of the industrial material (original rock composition, surface area and porosity) and the identification of key minerals, fluids, and weathering reactions, prior to employing remedial and preventative measures.FOLEY, N...
The catena concept describes soil properties on hillslopes and implies a hydrological mass redistribution process that has been applied differently in different parts of the Earth. In tectonically active regions, it is mostly used to describe the redistribution of mass by overland flow leading to thic...

Co-located geophysical and geochemical datasets in the borehole show a remarkably consistent picture of linked chemical and physical weathering processes, acting over a 38-m-thick regolith divided into three layers: soil; porous, highly weathered saprolite; and weathered, fractured bedrock. The data...
chemical weathering 岩石发生化学成分的改变分解,称为化学风化。例如,岩石中含铁的矿物受到水和空气作用,氧化成红褐色的氧化铁;空气中的二氧化碳和水气结合成碳酸,能溶蚀石灰岩;某些矿物吸收水分后体积膨胀;水和岩层中的矿物作用,改变原来矿物的分子结构,形成新矿物。这些作用可使岩石硬度减弱、密度变小或体积膨胀,促使...

Rocks can be broken into smaller pieces by a natural process known as weathering. Weathering refers to the chemical alteration and physical disintegration of rocks by the actions of air, water, and organisms. Two principal types of weathering are chemical weathering and biological weathering. The ...
