Landsberg domes
- Moon age 10.6 days (74
%) Directly north of Landsberg D (10 km) are three large but low domes, La 1 to 3. Their diameters are 20, 25 and 19 kilometers with a height of 120, 80 and 120 meters. All three domes have a striking oval shape, La 1 and La 2 show rilles (not visible on our image). All three domes are probably intrusive and in their morphological structure they are very similar to the Valentine and the Laplace domes. |

Putativer domecluster
Euklides - Moon
age 10.6 days (75 %) Montes Riphaeus in Mare Cognitum is a strange mountain range which also shows signs of volcanism. Directly to the east, beside the crater Euclid (12 km), there is a brighter area with a group of dome-like structures with a very steep flank angle. We would classify them as putatively effusive domes, similar to the steep domes Liebig 1 and Yangel 1 even when they are not so high. Their diameters are approximately 1.5 to 2 kilometers. |

LRO domecluster
Euklides The LRO image shows the six dome-like structures east of Euklides with a resolution of 64 m/px. |
 |
Kipuka Darney Chi -
Megadome Agartharchides and Putative domecluster Euklides -
Moon age 10.6 days (75
%) Darney Chi is a striking example of a lunar kipuka. By definition a lunar kipuka is an upwarp consisting of old highland material that has not been flooded by lava. So in fact no volcanic strukture. On the top of the image you can see the megadome Agatharchides and on the bottom the putative domecluster Euclid. The image resolution is around 1000 meters per pixel. |
 |
Landsberg and Putative domecluster Euklides -
Moon age 10.6 days (75
%) In this image the three Landsberg domes can be seen again. Furthermore, a putative pyroclastic deposit within the Montes Riphaeus is marked with a "2". North of the mountain range is a smaller putative Plateau. It clearly stands out from the surrounding lava and is assigned to the crater Darney (outside the image). |

NEW 2016 Lansberg Dome and
Darney Chi Kipuka -
Moon age 10.8 days (77
%) The Landsberg domes 1 to 3 at similar illumination as above. |
