What's the difference between diabase and variolite?

Diabase


Definition:

  • (n.) A basic, dark-colored, holocrystalline, igneous rock, consisting essentially of a triclinic feldspar and pyroxene with magnetic iron; -- often limited to rocks pretertiary in age. It includes part of what was early called greenstone.

Example Sentences:

  • (1) The gamma-glutamyltransferase inhibitor, AT-125, decreased cystine excretion, but only in the presence of glutathione, glycine, glutamate, and the diabasic amino acids.
  • (2) The results suggest that an active NS3 proteinase domain is necessary for cleavage at the diabasic nonstructural cleavage sites and that cleavage at the proposed 4A-4B signalase site requires prior cleavage at the 4B-5 site.

Variolite


Definition:

  • (n.) A kind of diorite or diabase containing imbedded whitish spherules, which give the rock a spotted appearance.
