Investigating reflectance properties of space weathered silicates: effect of swift heavy ion irradiation
Abstract
Space weathering strongly interests the surface of Mercury, affecting the characteristics of minerals and rocks. Here, we investigate the spectral variability from visible to mid infrared on three different silicates, partially covered by a thin film of carbon, irradiated with swift heavy ion at three increasing fluences. Ions and carbon affect spectral properties in different way from visible to near infrared; whereas in mid infrared only irradiation seems to contribute, describing an increasing process of silicate's amorphization.
