I disagree. Most major mountain ranges in the world have salt lakes or former salt lakes (salt flats). They are considerably more common than you appear to realise.
What the continents were like at the time being discussed, I do not know. Do you?
We are doing a differential here between shorelines of salt lakes and shorelines of the
I don't care how many salt lakes there are... Sea front is going to massively dominate.
According to the great oracle Wikipedia around 2.7 Ga ago we had a supercontinent named
Kenorland at that time, and while that would have reduced the coastline some, it's still going
to dominate over salt lakes. Particularly as a lot of rainfall over land is caused by plant life
[specifically trees] which pump large amounts of water into the air... and there was no land
plant life back then. Also supercontinents tend towards having large dessert interiors because
they are so far from the sea that they don't get rain.
All factors that make me fairly confident that probabilistically speaking lava flows hitting salt water
are much more likely to be hitting sea rather than land.
I'm by no means saying it's impossible [without knowing if they can rule such things out by studying
the rock formations for chemical signatures to differentiate sea salt water from salt lake water] but
it's got to be much less likely just given the sheer difference in scale between sea front and lake front.
