Most of the deposits that seem to be discussed are from the Noachian and Hesperian (~4.1 to 3.0 billion years ago). A bunch or magmatic deposits and maybe some evaporites.

Side note, evaporites on Mars is a PhD topic I was thinking about at some point. Still a bit sorry I didn't take that.

So, you can get geodynamic behavior similar to plate tectonics on Venus, but only in special circumstances and regionally limited as opposed to a global system like on Earth.

In Artemis Corona, Britomartis Chasma has a morphology and structure nearly identical to Mid-Ocean Ridges on Earth, complete with fracture zones! This is likely because Artemis Corona has some kind of ephemeral subduction occurring at it's southeast margin that produces a massive back-arc basin.

The short version (for the long version, read the paper) is that the majority of rifts on Venus aren't an equivalent to seafloor spreading (not surprising), but rather a global system of classical full- and half-graben. However, there is an exception that proves the rule.

I did this as part of my PhD dissertation. The goal was to model seafloor spreading on Venus and determine if it would look the same with Venusian temperatures and rheology as it does on Earth. It turns out that it does, and this has implications for Venus's global rift system.

These crazy deep sea fishes are now giving us new insights into how immune systems function, hopefully helping us develop better treatments for immune system disorders. This is why it's important to study our world simply for the sake of studying it. You never know what you're gonna learn

Why a NASA satellite that scientists and farmers rely on may be destroyed on purpose
The Trump administration has asked NASA staffers to draw up plans to end at least two satellite missions that measure carbon dioxide in the atmosphere, according to current and former NASA employees.

Government: This guy murdered a child he should be dismembered with a chainsaw and impaled on a pike on live television
Regular people: wait that's fucked up don't do that, what the fuck?
Government: oh so you support MURDERING CHILDREN?????
Moreover, ICE must be destroyed
