【摘要】：随着我国探月工程稳步开展以及未来深空探测需求,反射光谱学研究在我国重新受到重视。文中简要介绍了月球反射光谱学原理及其研究方法,并以"嫦娥三号"着陆场所在的雨海地区为例展示反射光谱学的部分应用。与背面斜长岩高地相对单调的光谱特征不同,雨海周边高地展示了多样性的吸收特征,岩石类型以苏长岩质岩石为主,橄榄石、辉石、尖晶石等矿物都有分布。月球上最古老的和最年轻的玄武岩在雨海盆地也都有分布。古老的中、低钛玄武岩以易变辉石为主兼有少量低钙普通辉石,年轻的高钛玄武岩富含橄榄石。雨海乃至整个风暴洋地区玄武岩较之其他月海玄武岩贫Ca。雨海地区的元素、矿物组成以及玄武岩时代都具多样性,该区是研究月球热演化的重要地区。
[Abstract]:With the steady development of our country's exploration and the future deep space exploration, the research of reflection spectroscopy has been revalued in our country. In this paper, the principle of the lunar reflection spectroscopy and its research methods are briefly introduced, and some applications of the reflection spectroscopy are presented in the rain and sea area of the "Chang 'e-3" landing place as an example. In contrast to the relatively monotonous spectral characteristics of the highlands of the diorite in the back, the surrounding highlands of the rain and sea show the absorption characteristics of the diversity. The rock types are mainly of the long-rock rock, and the forsterite, the pyroxene, the spinel and other minerals are distributed. The oldest and youngest basalts on the moon are also distributed in the rain and sea. The old middle and low-titanium basalts mainly contain a small amount of low-calcium pyroxene, and the young high-titanium basalts are rich in olivine. The basalts of the rain and sea and the whole of the storm are less than that of other monthly sea basalts. The composition of the elements, minerals and the age of the basalts in the rain and sea area is an important area for the study of the thermal evolution of the moon.
