I HAVE BEEN ON ARIMIDEX FOR 4 YEARS. I CAN NO LONGER HANDLE THE MANY SIDE EFFECTS OF THIS MED SO I HAVE STOPPED..ALTHOUGH I HAD EVERY INTENSION TO DO 5 YRS. DID A LOT OF RESEARCH, AND HAVE DONE MY BEST TO MAKE AN INFORMED DECISION THAT I CAN LIVE WITH. I FEEL AT PEACE WITH MY CHOICE.
Exfoliation is a form of rock weathering, also referred to as onion skin weathering. It is characterized by a layer by layer erosion of the outer surface of the rock caused by â¦ chemical changes to the composition of the minerals, by differences in temperature between the outer surface and the interior of the rock, or by the expansion and separation of the outer surfaces due to moisture absorption.
138Metamorphism is the isochemical process by which rocks are changed by either heat or pressure, or both heat and pressure. The chemical composition of the parent rock will be the same as the metamorphic rock produced.The rock undergoes the very slow process of solid-state recrystallisation without melting.ifferent temperatures and pressures cause new minerals to grow in rocks that have the same composition. The minerals produced are directly related to pressure and temperature conditions. The lower temperature limit for metamorphism is between 200 and 150 o C. Below these temperatures, changes are part of diagenesis.
