Using data from the Diviner Lunar Radiometer Experiment, we show that four regions of the Moon previously described as "red spots" exhibit mid-infrared spectra best explained by quartz, silica-rich glass, or alkali feldspar. These lithologies are consistent with evolved rocks similar to lunar granites in the Apollo samples. The spectral character of these spots is distinct from surrounding mare and highlands material and from regions composed of pure plagioclase feldspar. The variety of landforms associated with the silicic spectral character suggests that both extrusive and intrusive silicic magmatism occurred on the Moon. Basaltic underplating is the preferred mechanism for silicic magma generation, leading to the formation of extrusive landforms. This mechanism or silicate liquid immiscibility could lead to the formation of intrusive bodies.
利用“月球勘测轨道飞行器”的“Diviner”月球辐射仪实验数据，我们发现，此前被描述为“红斑”的月球四个区域的中红外光谱最适合用石英、富硅玻璃或碱长石来解释。这些岩石与阿波罗样本中的月球花岗岩等演化岩石一致。这些斑点的光谱特征与周围的海和高地物质以及由纯斜长石长石组成的区域明显不同。与硅酸光谱特征相关的各种地貌表明，月球上同时发生了喷发和侵入型的硅酸岩浆活动。玄武质底侵作用是产生硅酸岩浆的首选机制，从而导致了喷发地貌的形成。这种机制或硅酸盐液体不混溶作用可能导致侵入体的形成。
