Chemical Weathering – Physical Geology

Chemical Weathering Chemical weathering results from chemical changes to minerals that become unstable when they are exposed to surface conditions. The kinds of changes that take place are highly specific to the mineral and the environmental conditions.

Earth Structure, Materials, Systems, Cycles

Clay MineralsClay minerals are sheet silicates, thus they have a crystalline structure that allows them to break easily along parallel sheets. Clay minerals form by alteration of other minerals during the process of chemical weathering (alteration under conditions present near the Earth's surface).

What is Beryl? Beryl is a relatively rare silicate mineral with a chemical composition of Be 3 Al 2 Si 6 O is found in igneous and metamorphic rocks in many parts of the world.. Beryl has served as a minor ore of beryllium, and color varieties of the mineral are among the world’s most popular , aquamarine, heliodor, and morganite are the most wellknown varieties of beryl.

Pegmatite: Igneous Rock Pictures, Definition More

What is Pegmatite? Pegmatites are extreme igneous rocks that form during the final stage of a magma’s crystallization. They are extreme because they contain exceptionally large crystals and they sometimes contain minerals that are rarely found in other types of rocks.. To be called a "pegmatite," a rock should be composed almost entirely of crystals that are at least one centimeter in diameter.

Geochemical Prospecting

Mineral deposits represent anomalous concentrations of specific elements, usually within a relatively confined volume of the Earth's crust. Most mineral deposits include a central zone, or core, in which the valuable elements or minerals are concentrated, often in percentage quantities, to a degree sufficient to permit economic exploitation.

Gold Extraction Recovery Processes

It is desirable to have a method of plotting, in which equal distances on the plot represent equal, ratios of diameter, or, if we had been able to match the Rittinger scale precisely in getting the various sizingscreens, the data would be plotted at equal intervals on the horizontal scale, thus compressing the curve at the large end, and ...

Mining Wikipedia

To gain access to the mineral deposit within an area it is often necessary to mine through or remove waste material which is not of immediate interest to the miner. The total movement of ore and waste constitutes the mining process. Often more waste than ore is mined during the life of a mine, depending on the nature and location of the ore body.

GG101 Metamorphic Rocks

Metamorphic rocks can appear in many forms from platy, black, fine grained stone to granite like layered rock, to the marble used by sculptors. One explanation why a wide variety of metamorphic rocks exists is simply that there are many different sedimentary and igneous rocks, each responding to metamorphic conditions in its own unique way.
