The kinds of changes that take place are highly specific to the mineral and the environmental conditions. Some minerals, like quartz, are virtually unaffected by chemical weathering, while others, like feldspar, are easily altered. In general, the degree of chemical weathering is greatest in warm and wet climates, and least in cold and dry ...

Feldspar is one of the most abundant minerals in the earth''s crust. The feldspars include a range of compositions with a general chemical formula of xAl(Al,Si) 3 O 8 where x can be sodium (Na) and/or calcium (Ca) and/or potassium (K). They are primarily used in glass and ceramics making.
The fusibility of the mineral make it useful raw material for many application and the purity is the indication of better fusibility in the application. The geological context specific to each deposit gives the feldspar a variety of physical and chemical properties, thus providing products for a fullrange of ceramic and glass making applications.
Its range is from a few years to about 700,000 years. Potassium–argon dating and argon–argon dating. These techniques date metamorphic, igneous and volcanic rocks. They are also used to date volcanic ash layers within or overlying paleoanthropologic sites. The younger limit of the argon–argon method is a few thousand years.

Some Geology Basics Geology (geo: ''earth'', logos: ''knowledge or study of'') is the study of planet Earth. Geology is in many ways the most complex of sciences, as a complete understanding of the workings of the earth requires training in mathematics, chemistry, physics, biology, and astronomy. The study of
Individual crystals in LCT pegmatites can be enormous: the largest spodumene was 14 meters long, the largest beryl was 18 meters long, and the largest potassium feldspar was 49 meters pegmatites account for about onefourth of the world''s lithium production, most of the tantalum production, and all of the cesium ...
Geological ore deposits are of many different types and occur in all geological environments. ... more complex techniques have been developed to locate new deposits. However, better and more efficient processing techniques now mean that we can exploit ore deposits which were previously uneconomic. Economic viability of ore deposits.
