Summary
[edit]DescriptionVolcanic Rock in Scanning Electron Microscope.png |
English: A high-resolution electron micrograph acquired using backscattered electrons of an unprocessed volcanic basalt sample from Hawaii, using an electron landing energy of 5 keV. The rock is highly porous with large-scale porosity and contains many elements (this is a backscatter image, so the varying greyscale or brightness values in the image show areas with different atomic composition). The width of the image is approximately 190 µm, making the size of each pixel in the image approximately 30 nm. The large hole in the center of the image is the size of an average human hair |
