That actually makes a lot of sense. Basalt is sort of easy to find though. There is a series of valleys between Unionville and Badin and nearly every single one of them has basalt blocks. There is basalt in the creek behind my house. Thanks!

Heating things in closed containers like test tubes isn't a good idea.
Intraplate earthquakes are rare compared to those along plate margins- but their presence indicates that the crust can be strained in the middle of tectonic plates. Even though intraplate seismic zones are not well understood, they can be very active and produce large magnitude earthquakes. A couple of examples are the New Madrid seismic zone (1811-12) and the the Charleston seismic zone (1886).
