Lithification

The lithification event associated with carbonate dissolution and reprecipitation is reflected by a distinct strontium anomaly in the pore waters at a hundred to a few hundreds of meters subsurface depth (Figs. 9.3 and 9.24).The Sr 2+ concentration of biogenic calcite is three to five times higher than that of the inorganic calcite reprecipitated from solution (Baker et al., 1982; Elderfield ...

Quarrying Basics

Quarrying is quite simply the extraction of natural resources from the earth, usually from some form of surface working or quarry site. Quarries produce a range of useful materials, including limestone, dimension stone and rock. In Australia, the most common materials extracted are construction aggregates such as crushed rock, sand or gravel.

Situ Leaching

Ian Hore-Lacy, in Encyclopedia of Energy, 2004. 1.3 In Situ Leach (ISL) Mining. In situ leaching (ISL), also known as solution mining, involves leaving the ore where it is in the ground and using liquids that are pumped through it to recover the minerals out of the ore by leaching. Consequently there is little surface disturbance and no tailings or waste rock generated.

Inherent Factors Affecting Soil Infiltration

Dislodged soil particles fill in the surface pores, contributing to the development of a surface crust, which restricts the movement of water into the soil. Equipment use, especially on wet soils, and tillage can result in compaction. Compacted or impervious soil layers have less pore space, which restricts water movement through the soil profile.
