The stone meteorites. The nickel iron compound is in the most stone meteorites that is why the space stones are heavier than the terrestrial ones. But their main minerals are silicates (olivine and pirogues). The characteristic of the main type of the stone meteorites - hondrits - is the round formations into them - so called “honds”. ... Their origin is not clear yet. The internal structure of the stone meteorite . Back . ...

Color separation notes ====================== As an example I took the raw Nikon image file DSC_0100.NEF and processed it with Cinepaint to read all 16 bits in each color. I stored the resultant image as DSC_0100.TIF which is a 16-bit format that ImageJ can read. ... When read in with ImageJ, the color tif file will display as a stack. ... Consequently the usm images are not color shifted from the original, have a less contrast than the hc images, but noticably enhance rays and crater edge detail. ...
