A-CN-K (Al2O3- (CaO*+Na2O)-K2O) diagram A–CN–K ternary plot is useful tool to evaluate weathering trends in the source rock and to estimate K-metasomatism [Nesbitt and Young (1982‚ 1984); Fedo et al.‚ 1995]. The ideal weathering lines are parallel to A-CN boundary because the removal rates of Na and Ca from plagioclase are greater than the removal rate of K from k-feldspars. On the A–CN–K ternary plot (Fig.6.16) the samples are plotted more or less close to A - K boundary indicating that removal

National Distribution Centre and the well known popular Hard Rock Café. TRANSFORMATION PROCESS Both companies follow the same traditional Production System model with inputs relating to money and labour with the same outputs resulting in producing a good or service. However if we compare the transformation processes‚ both companies have different objectives especially in the output result as IGA’s output is based on tangible goods and Hard Rock Café is based on service being an intangible good.

sediment. Would a rock formed from cemented particles of volcanic ash be igneous or sedimentary? Can you think of other circumstances that might form rocks that are intermediate between two of the major rock families? The rock would be igneous‚ igneous rocks are formed from the solidification of molten rocks. Rocks can be formed in numerous ways a few examples are erosion and earth quakes. I think that metamorphic rocks are the perfect example for combining all the three different rocks together because

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.

living creatures‚ but many do not realize how toxic it can be to non-living objects. “Acid rain leads to deterioration of rocks such as limestone and marble (globalwarmingandu.com)”. Acid rain will corrode the rock surface which dissolves the material and then they will be carried away. We tested acid on different types of rocks. The hypothesis is that the sedimentary rock will have the largest change in mass. After a certain degree‚ acid rain is capable of damaging the entire environment. It
