The Interpretation of the Land Form of Sinus Iridum on the Moon Based on the Roughness
摘要
Abstract
The planetary surface roughness is the record of erosion, deposition, uplift and other geological processes on the planetary surface, and hence serves as a prediction for the geological age of the planetary surface. In this paper, twelve profiles were selected in the horizontal direction of the Sinus Iridum in the moon, and several parameters of roughness of those profiles were studied. Some results have been obtained: d)The average of RMS height along the profile 1 km in length is about 3m. In addition, within the research scale selected in this paper (0. 2 ~ 3 km) , the slope of Sinus Iridum area does not exceed 2 °. This means that the surface of Sinus Iridum is relatively smooth. (2)Hurst exponent of Sinus Iridum is mainly concentrated from 0. 5 to 0. 78 , which means that the surface morphology is rather homogeneous. ③Low latitude areas (lower than 44. 3° N) have relatively high Hurst exponent (from 0.6 to 0. 8) , and high latitude areas (higher than 44. 3° N) usually have lower Hurst exponent ( from 0.5 to 0. 8 ). (4)The roughness may be used as a means to determine the relative geological age.关键词
