What's the difference between dolerite and doleritic?
Dolerite
Definition:
(n.) A dark-colored, basic, igneous rock, composed essentially of pyroxene and a triclinic feldspar with magnetic iron. By many authors it is considered equivalent to a coarse-grained basalt.
Example Sentences:
(1) The find has been made by professors Tim Darvill and Geoffrey Wainwright, who have spent the last 10 years trying to establish how and why the bluestones – or spotted dolerite – were transported from the Preseli hills to Stonehenge.
(2) It began as a timber circle, later made permanent with massive blocks of stone, many somehow dragged from dolerite rock in the Welsh mountains.
(3) Respirable quartz concentrations and calculated cumulative time weighted exposures were below those recommended for industry during grinding with sandstone (100% quartz) and they were even lower during grinding with dolerite containing no quartz despite the presence of an appreciable amount of quartz in the ground maize.
Doleritic
Definition:
(a.) Of the nature of dolerite; as, much lava is doleritic lava.
