As the BBC reports, Robert Ixer of the University of Leicester and Richard Bevins of the National Museum of Wales pinpointed the source to within 230 feet and did so by "detailing the mineral content and the textural relationships within the rock, a process known as petrography." ❋ Unknown (2011)
By detailing the mineral content and the textural relationships within the rock, a process known as petrography, they found that 99% of the samples could be matched to rocks found in this particular set of outcrops. ❋ WalesOnline (2011)
Oh, that one's a P.Geo - a professional geologist - is can log drill holes, update and construct geological models, they are experts in igneous and metamorphic petrology and petrography, hydrogeology, sedimentolgoy and structural geology. ❋ ReBecca Foster (2008)
The geomorphology of the area reflects its geological constitution, in particular its petrography and tectonic structure. ❋ Unknown (2008)

These are splendid specimens that give us a peek at some awesomely fragile organisms, and modern technology helps by giving us new tools, like x-ray computed tomography (CT), scanning electron microscopy (SEM), thin-section petrography, synchrotron X-ray tomographic microscopy (SRXTM), and computer-aided visualization, that allow us to dig into the fine detail inside these delicate specimens and display and manipulate the data. ❋ Unknown (2006)
These sample will be analyzed mineralogically (petrography, X-ray diffraction) and geochemically (Inductively Coupled Plasma-Mass Spectrometry, X-Ray Fluorescence) to identify and characterize the ore deposits and the metal production waste. ❋ Unknown (2003)
"Business has been a bit slow, of course, what with the weather, but I've been keeping my hopes up that fine gentlemen like yourselves would need professional assistance with matters in geology, petrography, mineralogy, or even gemology, such as it may be, and I graduated first among my guild in mine engineering and geology, with a secondary degree in mechanics ...." ❋ Weis, Margaret (1994)
To the graduates were assigned courses in advanced geology, mineralogy, petrography, advanced economic geology, and the economic geology of the Southern Appalachians. ❋ Unknown (1922)
Professor T.L. Watson, the new incumbent of the chair of geology, delivered a series of specialized lectures, — accompanied by laboratory and field work, — on engineering geology, economic geology, and petrography; and in 1908 – 09, Professor R.M. Bird, of the chemical faculty, gave instruction in chemical engineering. ❋ Unknown (1922)
The City worried him a good deal, and what energy he had left over he spent partly in golf, a game he treated very seriously, and partly in the practices of microscopic petrography. ❋ Herbert George (1909)
A faint buzz above the ceiling witnessed that petrography, too, was active. ❋ Herbert George (1909)
After dinner Ann Veronica went into the drawing-room with Miss Stanley, and her father went up to his den for his pipe and pensive petrography. ❋ Herbert George (1909)
