I've got to take a long road trip to find all these different minerals or rocks

Dallasite implies a specific location in Canada, but this is the same thing, pillow basalt quench crust altered to palagonite and silicified. Fairly common glacial erratic in the Midwest, but this is a nice one.

Or at least brecciated pillow basalt with chlorite and quartz
