Mudrock - Wikipedia

Clay is by far the smallest particles recognized in mudrocks. Most materials in nature are clay minerals, [clarification needed] but quartz, feldspar, iron oxides, and carbonates can weather to sizes of a typical clay mineral. For a size comparison, a clay-sized particle is 1/1000 the size of a sand grain.

Limestone - Wikipedia

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals [[]] and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.

Electrical resistivity of geologic materials - eoas.ubc.ca

In the presence of water and CO 2 rocks are broken down into ions (often dissolved and removed by drainage), clay minerals are formed, water is used up (becomes part of clay compounds), and solutions become more basic (i.e. less acidic). The process is self perpetuating since a thin layer of soil will cause the relevant processes to occur more ...

Limestone - digitalfire

The calcium carbonate used in ceramics is simply limestone ground into a powder (not calcined and is therefore stable). While not intuitive (given the high LOI and propensity to regenerate), in some countries (e.g. Thailand) limestone powder (about 10-20%) is added to clay bodies (fired 700-900C).
