Last week, the perseverance team was surprised by a strange rock consisting of hundreds of fields in the size of a mm … and the team is now working hard to understand their origin.
It has now passed two weeks since the arrival of the perseverance to Brom Point, which is located in the bottom slopes of the Hazel Hill area, on the edge of Jezero Crate. Here, a series of light and dark music bands were visible from orbit, and only last week, Rover succeeded in postponing and taking samples from a light color family. It was from this sampling area where perseverance was spying on a very strange texture in a nearby rock …
It seems that the rock, which is called “Saint Bols Bay” by the team, consists of hundreds of darker gray fields. Some of these most elongated and elliptical forms occurred, while others have the edges of the angles, and may represent broken aromatic fragments. Some fields have small gaps! What is Quirk of geology that can produce these strange forms?
This is not the first time that strange balls have been monitored on Mars. In 2004, the Mars Explography ROORIRATIORATIONARATIONARATIONIRA ROOR opportunity was monitored, “Blue Mars” in Meridiani Planum, and since then, Rover has noticed curiosity in the yellowknife bay rocks in Gale Crate. Just a few months ago, the same perseverance was also spied of popcorn -like textures in the exposed sedimentary rocks on Jezero Crate Inlet, NERETVA VALIS. In each of these cases, holidays were interpreted as concrete, which are features formed by the interaction with the groundwater circulating across the pores in the rock. Do not form all fragments in this way. It is also formed on the ground by rapid cooling of molten rock drops that were formed in a volcanic eruption, for example, or by intensifying the rocks that evaporated the effect of the meteorite.
Each of these composition mechanisms will have various effects to the development of these rocks, and therefore the team is working hard to determine its context and its origin. However, the Gulf of St. Paul was a floating rock-a term used by geologists to describe something that does not exist. The team is now working to connect the rich texture to the aromatic that was observed in St. Paul Bay to the wider layer in Witch Hazel Hill, and the initial notes have provided confusing indications that it can be linked to one of the dark classes set by the team from the orbit. Putting these advantages in the geological context will be very important to understand their origin, and define its importance to the geological history of Jezero Crate RIM and beyond!
