Little is known about the history of the oldest exposed rocks in the area due to extensive metamorphism.This somber, gray, almost featureless crystalline complex is composed of originally sedimentary and igneous rocks with large quantities of quartz and feldspar mixed in. [1] The original rocks were transformed to contorted schist and gneiss, making their original parentage almost unrecognizable.
Instead much of the value of the discovery was in the insight it provided into the material culture of ancient Egypt. [98] Among the furniture was a foldable bed, the only intact example known from ancient Egypt. [99] Some of the boxes could be latched with the turn of a knob, and Carter called them the oldest known examples of such a mechanism ...
Paleoradiology. A Peruvian child mummy being placed onto a CT machine for imaging. Paleoradiology (ancient radiology) is the study of archaeological remains through the use of radiographic techniques, such as X-ray, CT (computer tomography) and micro-CT scans. [1] It is predominately used by archaeologists and anthropologists to examine ...

The geology of Nebraska is part of the broader geology of the Great Plains of the central United States. Nebraska's landscape is dominated by surface features, soil and aquifers in loosely compacted sediments, with areas of the state where thick layers of sedimentary rock outcrop. Nebraska's sediments and sedimentary rocks lie atop a basement ...
