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.
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
The location and recovery of these metals has been a key facet of the study of geology since its inception. Every element across the periodic table has specific applications in human civilization. Metallic mineral mining is the source of many of these elements. Types of Metallic Mineral Deposits
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 ...

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 ...
