The convention where geologists draw certain rock layers like bricks has always confused me deeply. I get it's shorthand for "rock with cracks that water might flow through" ... and when you are drawing in pen it's easy to run out of ways to indicate different regions with simple patterns...but I keep thinking it's man-made.

@futurebird forget flat earth theory, now we have brick earth theory. It's the empirically observable shape but the whole thing was built by construction contractors

@futurebird Slartibartfast would never have used such mundane construction in his fjords!

@futurebird that said - I feel like this style was very common late last century but has become less common since then. this wikimedia page has 2 examples out of 40. https://commons.wikimedia.org/wiki/Category:Hydrogeological_cross_sectionsthis one has 4 examples in the first 100. https://commons.wikimedia.org/wiki/Category:Geological_cross_sectionsIn both cases I did not look into subcategories.

@futurebird lol yesPlaying with MS Paint years ago, I found it was easy to sketch natural-looking sedimentary stone. The Powder Toy has similar drawing characteristics; I used it to illustrate my own neighborhood karst 😜 Alas, crude drawing tools don't do diagonals well.https://powdertoy.co.uk/Browse/View.html?ID=2569567https://powdertoy.co.uk/Download.html

@futurebird This post was immediately next to yours on my timeline - perhaps for a reason...? 😂 https://infosec.exchange/@wendynather/114409994498624604

@futurebird As a geoscientist, I have learned that the brick structure is used as a symbol for limestone to distinguish it from other units such as sandstone or mudstone on geological maps and graphic logs (alas, I am not a sedimentologist). I would never use it for an illustration like that since it's just lazy as someone already pointed out in the comments.

@futurebird New conspiracy theory unlocked:The entire Earth is manmade. They've been lying to us all this time!Also, don't drill down and check. Just trust the pictures.

@jaypdub @llewelly @futurebird Thanks for giving an informative, but concise, explanation, John.In case anyone wants a more expansive answer, here's an official summary of standard lithological (rock type) symbols:https://ngmdb.usgs.gov/fgdc_gds/geolsymstd/fgdc-geolsym-sec37.pdf

@oldclumsy_nowmad @jaypdub @llewelly Thank you so much! This is just the kind of thing that I suspected must exist... but being only vaguely interested in geology I didn't know how to find it or explain it. I could tell there was some methodical meaning encoded in the "confusing bricks" choice. I'm delighted.
