Maghemite forms by weathering or low-temperature oxidation of spinels containing iron(II) such as magnetite or titanomagnetite. Maghemite can also form through dehydration and transformation of certain iron oxyhydroxide minerals, such as lepidocrocite and ferrihydrite. It occurs as widespread brown or yellow pigment in terrestrial sediments and ...
A sample page from Biblia Hebraica Stuttgartensia (Genesis 1,1-16a).. The Biblia Hebraica Stuttgartensia, abbreviated as BHS or rarely BH 4, is an edition of the Masoretic Text of the Hebrew Bible as preserved in the Leningrad Codex, and supplemented by masoretic and text-critical notes.

Presently coral is found in the Mediterranean , the northern coast of Africa furnishing the dark red, Sardinia the yellow or salmon-colored, and the coast of Italy ...
Iron(II,III) oxide, or black iron oxide, is the chemical compound with formula Fe 3 O 4.It occurs in nature as the mineral magnetite.It is one of a number of iron oxides, the others being iron(II) oxide (FeO), which is rare, and iron(III) oxide (Fe 2 O 3) which also occurs naturally as the mineral hematite.
and octahedral sites are occupied by both Fe 3+ and Fe 2+. Maghemite differs from magnetite in that all or most of the iron is in the trivalent state (Fe 3+) and by the presence of cation vacancies in the octahedral sites. Maghemite has a cubic unit cell in which each cell contains 32 oxygen ions, 21 1 ⁄ 3 Fe 3+ ions and 2 2 ⁄ 3 vacancies ...
Beri'ah (בְּרִיאָה or alternatively [2] בְּרִיָּה), meaning World of Creation. On this level is the first concept of creatio ex nihilo (Yesh miAyin), however without yet shape or form, as the creations of Beriah sense their own existence, though in nullification of being (Bittul HaMetziut) to divinity. Beriah is the realm of ...
A version of the documentary hypothesis, frequently identified with the German scholar Julius Wellhausen, was almost universally accepted for most of the 20th century. [5] It posited that the Pentateuch is a compilation of four originally independent documents: the Jahwist , Elohist , Deuteronomist , and Priestly sources, frequently referred to ...
