Moissanite, SiC, is an uncommon accessory mineral that forms under low oxygen fugacity. Here, we analyze natural SiC from a Miocene tuff-sandstone using synchrotron Laue microdiffraction and Raman spectroscopy, in order to better understand the SiC p

The transformation of diamond to graphite: Experiments reveal the presence of an intermediate linear carbon phase

Autor: Larissa F. Dobrzhinetskaya, E. F. O'Bannon, Richard Wirth, F. Shi, A. King, G. Xia

Publikováno v: Diamond and Related Materials

Natural diamonds that have been partially replaced by graphite have been observed to occur in natural rocks. While the graphite-to-diamond phase transition has been extensively studied the opposite of this (diamond to graphite) remains poorly underst

Not all moissanites are created equal: New constraints on moissanite from metamorphic rocks of Bulgaria

Autor: Krassimir N. Bozhilov, Larissa F. Dobrzhinetskaya, Qin Wang, E. F. O'Bannon, P. Machev

Publikováno v: Earth and Planetary Science Letters. 498:387-396

Terrestrial moissanite (SiC) is widely reported as an ultra-high pressure mineral occurring in kimberlites, diamonds and ultramafic/mafic rocks of mantle origin. However, the conditions of crystallization remain largely unknown. Moreover, dozens of S

Moissanite (SiC) with metal-silicide and silicon inclusions from tuff of Israel: Raman spectroscopy and electron microscope studies

Autor: E. F. O'Bannon, Tatiana Sokhonchuk, Richard Wirth, Wenxia Zhao, Larissa F. Dobrzhinetskaya, Qin Wang, Pavel Mukhin, Lev Eppelbaum

Publikováno v: Lithos

Here, we present studies of natural SiC that occurs in situ in tuff related to the Miocene alkaline basalt formation deposited in northern part of Israel. Raman spectroscopy, SEM and FIB-assisted TEM studies revealed that SiC is primarily hexagonal p

High-Fe (Mg, Fe)O inclusion in diamond apparently from the lowermost mantle

Autor: Larissa F. Dobrzhinetskaya, Harry W. Green, Richard Wirth, Anja Schreiber, Ben Harte

Publikováno v: Earth and Planetary Science Letters

The only direct samples of Earth's lower mantle are rare inclusions in diamonds. The most abundant are (Mg, Fe)O, showing highly magnesian compositions. Here we report a transmission electron microscopy study of an exceptional inclusion with composit

Qingsongite, natural cubic boron nitride: The first boron mineral from the Earth's mantle

Autor: Harry W. Green, Edward S. Grew, Peter K. Weber, Richard Wirth, Jingsui Yang, Larissa F. Dobrzhinetskaya, Ian D. Hutcheon

Publikováno v: American Mineralogist

Qingsongite (IMA 2013-30) is the natural analog of cubic boron nitride (c-BN), which is widely used as an abrasive under the name “Borazon.” The mineral is named for Qingsong Fang (1939–2010), who found the first diamond in the Luobusa chromiti
