Am seeking all help re:info about basalt containing phenocrysts. I have several chunks of rock material which are filled with small spherical waxy/glassy/mostly translucent deposits of a silica-like substance. They came to me through the estate of a early/mid-20th century rockhound, and I am curious to find out more; especially hoping for images, to do visual comparision with. HELP PLEASE? Any and all advice, etc. is greatly desired, and you have my thanks in advance...
