Xia Xiaoping Research Projects Multi-technique dating of high-pressure rocks in the Central Zone of the North China Craton (M Sun, G Zhao, S A Wilde) The recent discovery of high-pressure amphibolites and granulites, and retrograded eclogites in the central zone of the North China Craton may provide evidence that supports the operation of plate tectonics in the early history of the Earth. The results of this geochronological investigation, combined with tectonothermal and geochemical data, are intended to test the validity of our recent tectonic model that the central zone represents a Palaeoproterozoic collisional orogen along which two Archaean continental blocks were juxtaposed by plate teconics to form the North China Craton. LA-ICP-MS study of detrital zircons from khondalites in the Sino-Korean Craton (M Sun, G Zhao) High-grade meta-sedimentary rocks, khondalites, occur along the northern margin of the Sino-Korean Craton and their age has great implications for its tectonic history. To unravel the depositional and metamorphic history of these rocks, U-Pb isotope spot-analysis using LA-ICP-MS of zircons identified by cathodoluminescence imaging combined with Th/U ratios, combined with field and geochemical studies, will be used to reveal the sedimentary source, nature of the provenance, and depositional and metamorphic ages of the khondalites.

The studies of radiometric dating and geochemical reference samples conducted in this department are indispensable for many geological researches. Useful data for environmental and exploration work are provided through the applied geochemical research on the abundance and behavior of elements, isotopes and organic compounds in soils, rocks and minerals. Analytical Methods GSJ develops analytical methods of determining the chemical and isotopic composition of rocks, minerals and other natural materials. They include Atomic Absorption Spectrometry (AAS), X-ray Fluorescence Spectrometry (XRF), Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES), ICP-Mass Spectrometry (ICP-MS), Instrumental Neutron Activation Analysis (INAA), Thermal Ionization Mass Spectrometry (TIMS) and Secondary Ion Mass Spectrometry (SIMS).

Puchtel: Laboratory Manager ipuchtel AT umd.edu (top) Peridotite xenolith from a quarry near Yangyuan, China was erupted onto the surface approximately 38 million years ago. Materials like this are examined in order to study the evolution of the lithospheric mantle underlying the North China Craton. Evidence suggests that the ancient lithospheric mantle that underlay China as late as the mid-Ordovician has been replace by younger mantle represented by the rock shown. (bottom) Lunar impact melt rock 14321. This approximately 3.85 billion year old rock and other lunar breccias formed by the massive impacts that generated the large lunar basins are studied in order to better constrain the chemical characteristics of planetesimals that impacted the Moon and Earth at that time.

Petrology From Wikipedia, the free encyclopedia Jump to: navigation search This article includes a list of references , related reading or external links , but its sources remain unclear because it lacks inline citations Please improve this article by introducing more precise citations where appropriate (December 2008) A volcanic sand grain seen under the microscope, with plane-polarized light in the upper picture, and cross polarized light in the lower picture. Scale box is 0.25 mm. Petrology (from Greek: πέτρα, petra , rock; and λόγος, logos , knowledge) is the branch of geology that studies rocks , and the conditions in which rocks form. Lithology once was approximately synonymous with petrography , but in current usage, lithology is a subdivision of petrology focusing on macroscopic hand-sample or outcrop-scale description of rocks, while petrography is the speciality that deals with microscopic details. In the oil industry , lithology, or more specifically mud logging , is the graphic representation of geological formations being drilled through, and drawn on a log called a mud log . As the cuttings are circulated out of the borehole they are sampled, examined (typically under a 10x microscope) and tested chemically when needed.
