Crazily eroded rock on Mars

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken today by the Perseverance Mars rover, using its SHERLOC-WATSON close-up camera at the end of its robot arm.
The size of this rock is tiny, no more than a few inches across. The many holes remind me of surface limestone on Earth. When it rains, the water dissolves the limestone, and so holes will develop and grow over time. You can see this process if you spray very hot water on top of a block of ice.
The problem is that it doesn’t rain on Mars. Lava can sometimes freeze and look this way, but is it lava? The blue dot on the overview map above shows where Perseverance was two days earlier. The rover team has not updated that map so it is not known exactly where the rover was when it snapped this picture today. Nor has the science team posted an update on their activities since June 27th.
These strange features however mirror somewhat the same surface features seen back in June, when the rover was on the north side of Neretva Vallis, so it is likely this rock was produced by the same geological processes. I will however not guess what those processes were.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.

Looks like vesicular basalt where trapped gases created the vugs or holes in the rock as it cooled. It would be interesting to know if this was an isolated rock(s) or part of a larger formation/out-cropping. On earth these can contain many other minerals. I wish I could open one up with a rock hammer. Mars is like a box of chocolates – you never know what you’re going to get.
