Mangaroon orogeny

The Mangaroon orogeny was an orogenic event in what is now Western Australia between 1.68 and 1.62 billion years ago in the Proterozoic, preserved in the rocks of the large Gascoyne Province.

Interpretation of events

Beginning 1.7 billion years ago, widespread sedimentary rocks deposited across the Gascoyne Province, including fluvial conglomerate and sandstone. These are the protoliths of the Pooranoo Metamorphics and span Errabiddy Shear Zone, Limejuice Zone and Mangaroon Zone. During the Mangaroon orogeny, huge volumes of granite belonging to the Durlacher Supersuite intruded rocks in the Mangaroon Zone as high-grade metamorphism and deformation occurred. The Pooranoo Metamorphics reached amphibolite-grade on the sequence of metamorphic facies becoming gneiss. Like the Capricorn orogeny, the Mangaroon orogeny is interpreted as an intracontinental deformation event due to distant collisions at the edges of the continent rather than an ocean-closing event.

gollark: Also, in that version there, patterns got fed in as a table with numeric indices from 1-9 representing each slot of the crafting table plus an optional qty key for how much the recipe produces.
gollark: Ridiculous. We *need* to be able to break maths in a snippet of code.
gollark: Here is a copy of the code I don't understand from the old version:```lualocal function descend(intermediateFn, terminalFn, i) local pattern = patterns[i] if pattern then intermediateFn(pattern) local pqty = pattern.qty -- Qty keys must be removed from the pattern for collation -- Otherwise, it shows up as a number stuck in the items needed table, which is bad. pattern.qty = nil local needs = util.collate(pattern) pattern.qty = pqty local has = {} for slot, item in pairs(pattern) do if util.satisfied(needs, has) then break end if patterns[item] then descend(intermediateFn, terminalFn, item) has[item] = (has[item] or 0) + (patterns[item].count or 1) end end else terminalFn(i) endendlocal function cost(i) local items = {} descend(function() end, function(i) table.insert(items, i) end, i) return util.collate(items)endlocal function tasks(i) local t = {} descend(function(pat) table.insert(t, pat) end, function() end, i) return tend```
gollark: Also, implementing whatever is done internally for finding free space to transfer to is hard!
gollark: I'm unlikely to have stupidly large autocrafting trees.
