     · This protected the wood from the elements and prevented their decay, and slowly, over millions of years, the silica minerals (quartz, chalcedony, jasper) were carried by water seeping into the wood and replaced the structure of the original tree on a microscopic level, atom by atom. So fine is this process of replacement that the cellular structure can still be observed. .

  • What vitamins and minerals are destroyed by heat?

    Minerals cannot be destroyed by heat, air, acid, or mixing. Compared to other nutrients such as protein, carbohydrates and fat, vitamins and minerals are present in food in tiny quantities. This means that fat or oil must be consumed for the vitamins to be absorbed by the body. Secondly, is vitamin B destroyed by heat? B vitamins are similarly heat sensitive. Up to 60% of thiamine, .

  • Diagenesis on Clastic Sedimentary Rocks Free Essay Example

    According to Burley and Worden (2003), dissolution is the process in which a mineral is destroyed as a result of the interaction with an aqueous solution/fluid and the consequence of this is a cavity or space on the mineral grain/ host sediment. This process does not have a very intense effect of clastic sedimentary rocks due to the resistivity of the clasts. However, silica is .
