Ancient Specimen Story Trait Often Leads to Sour Gas

The ancient specimen story trait often will spawn a magma patch in abyssalite in the middle of an oil biome at the bottom of the map (probably not on Verdante).  That patch only has one layer of abyssalite.  Since there often exist concentrated pockets of oil around, some oil will manage to exert enough pressure on the abyssalite to break the abyssalite and then magma mixes with oil and heats with the result of a naturally made sour gas boiler (but no condenser).  I think I've also seen the magma just break one tile of abyssalite all by itself once, though I'm not sure of that.
