This project is inteded to enhance the technical writing skills of petroleum engineering students in Cairo University. In addition, delivering a full picture of the branches of petroleum geology is an indirect objective of the pages to be written in this sandbox. By the end of this project, students will develop a peer review to check each others' work and develop a critique that is constructive to their colleagues. The following 8 pages are in this category, out of 8 total.

Diatomite The term'Diatomite' is used to refer to biogenic, siliceous deposits composed mainly of the frustules of diatoms with varying amounts of detrital material, mainly clay & silt. The diatoms, which are pelagic phyto-plankton, are composed of amorphous colloidal silica, in the so-called Opal A phase of silica mineralogy. The diatoms sink to the bottom of the ocean or lake to form an ooze that gradually becomes lithified as the water is squeezed out. At about 125ºF, due to increasing depth of burial, the Opal A becomes unstable and changes diagenetically into Opal CT. (Opal CT is sometimes called'porcelanite' because it has a porcelain-like texture.) Dissolution and recrystallization of the Opal A results in the minerals cristobalite & tridymite, which are more stable forms of silica.
