BASALT DYKE IN THE BEACH - PRAIA MOLE

Dyke of basalt in Mole beach
 

Basalt (?) dyke in granite basement of Mole beach in Florianópolis city, SC state.

Note that orientation are 25° NE in every dyke in the site. I suppose that orientation are due to split the supercontinent of Gondwana. These separation of two continental mass give raise the Africa continent and America continent.
