In case of valorisation of natural resources of the country‚ the project wishes to focus on creation of ceramic production units‚ therefore‚ the sponsors‟ attention should focus on a number of certain clay‚ feldspar and kaolin deposits. 1.

difference in the process between carbonation and oxidation. When carbon dioxide in the air dissolves in rain‚ a weak carbonic acid is formed. This weak acid‚ while harmless to plants and animals‚ is able to dissolve some kinds of rocks‚ like feldspar and limestone‚ in a process called carbonation. Many caves begin forming during the process of carbonation. On the other hand‚ any mineral that reacts with oxygen in the atmosphere will produce an oxide. Therefore‚ when an object made of iron is

Porphyritic granite Porphyritic granite is an igneous rock‚ which consists of orthoclase feldspar‚ quartz and orthoclase. This type of rock is made up of two different grain sizes‚ larger crystals referred to as phenocrysts‚ and smaller granite sized grains. The name for porophyritic originated from the Latin word porphyry which is defined as purple‚ and is known as a color royalty. This rock has been used as early as 18 AD and was discovered by a Roman legionnaire named Cauius Cominius.
