Rimae Sirsalis and Rimae Darwin

Recommended Posts

Judging by what you read on the Internet recently there is much confusion and disagreement over a large channels or slots lunar. Different sites say Sirsalis Rille, shown in the screenshot below, is an all or lava lava channel, but some also admit confusion volcanic feature that could form in the highlands of the Moon instead of forming seas. The word rille (channel or groove) is used to describe a variety of valleys that are considerably longer than wide. Sinuous channels, like Marius, are volcanic lava tubes and channels. The linear, as Ariadaeus and concentric as Hippalus cracks are usually associated with the tectonic stress regime associated with impact basins. The channels are interpreted as linear depressions formed on vertical beams of magma called dykes. The dykes are born in regions where the horizontal stress is extensional, making it easy to push up the dike rocks around. The Sirsalis Rille is one of the major channels, or linear grooves of the moon, with about 380 km long. According to references, the channel has a maximum width of 3.7 km and an average depth of 230 meters. What supports the interpretation of this channel as a volcanic dike are the magnetic measurements made by Apollo and Lunar Prospector spacecraft showed that a large linear anomaly on the dyke. The Sirsalis Rille is between 8 or 10 channels approximately radial to the hypothetical impact basin Gargantuan which had its western third filled by Oceanus Procellarum. Somehow the dikes are related to the vast depression Gargantuan, but exactly how this relationship occurs is still a mystery.
The Channel Sirsalis is fascinating as well as being great at length he has a strong gravitational field, but the channel seen in the picture below can also be considered remarkable because it falls within the crater De Vico A and then scale your wall. Looking so it looks like it came like lightning in this region. But he came but thanks to forces from below, apparently a vertical sheet of magma probably also traveled laterally and fed lava to the Oceanus Procellarum. How the channel can not float it is lower inside the crater than your ring. The channel then crosses the interior of a large unnamed crater where it undergoes a major shift. The reason for this deviation is quite mysterious, but one thing that is clear is a series of channels that seem to get in Sirsalis and head to Darwin, where a strong pipeline crosses diagonally inside. Canals sometimes seem to have lives of their own doing what they want to do. At least that's how they seem to be when we can not understand the forces that created them.
