Sherds of Khirbet Kerak Ware vessels, dating back to 2750–2500 B.

To discover if mass transfer was accomodated by microcracks during deformation, X-ray element mapping was also employed.

The combination of imaging techniques facilitates observation and interpretation of the rocks’ microscale features.

Cross sections of the black encrusted regions show that the stone’s red coloration has been modified by black pigmentation from the surface down to ~250 μm.

I am interested in exploring the isotopic records of mollusk shells from the Panamanian region to address questions of climate change, circulation patterns, and evolutionary responses to environmental stimuli.

Scanning electron microscopy and EDS-based x-ray microanalysis of the uppermost portion of the cross section reveal nanometer scale (1 μm) at the surface.

The Uweinat–Kamil basement complex, in the central part of the East Sahara Ghost Craton (ESGC) in NE Africa, is the only inlier in the craton that contains rocks with Archean formation ages, and is hence a key to understanding the ancient crustal evolution of the otherwise enigmatic and poorly known ESGC.

Multiple generations of microcracks, some annealed, within the Salihli and Turgutlu granites provide evidence that the rocks experienced pulses of extension.

The Smithsonian Institution Building, commonly referred to as the Castle, is located on the National Mall in Washington, DC, and was constructed in the mid-nineteenth century for the purpose of housing all museum and scientific functions for the newly formed institution.The results on Khirbet Kerak Ware are then compared with those of ceramics of the same period found at that site in order to highlight possible differences or similarities in the manufacturing process.

Nevertheless, it is believed that the mutation of the sex-determining gene and the fertilization of an ovum by two sperms are possible causes.… continue reading »
