Аннотация: The big volume of water ice exists on the Mars within the north polar layered deposit (NPLD). Layering of the polar cap deposits is caused by alternation of water ice layers with ifferent impurity of silicate dust [4]. The remnant massifs of the bright layered deposits (RMBLD) are located around the north polar cap. The deposits have the same layering structure, as we can find at the polar cap [5,6]. Research of material composition of the RMBLD around the polar cap can explain genesis of them and evolution of Mars atmosphere. In the previous research we made structure analyses of the RMBLD, as well as a spatial distribution mapping and typing [4,5]. Typing of the RMBLD was based on morphology and location on the surface. Identified the same structure of the RMBLD and the NPLD, we made analyses of the OMEGA mapping spectrometer data and the THEMIS day-time IR images, which show a lowest values of both thermal emissivity of the RMBLD surface and their brightness temperature, converted from the images.
