Question

write notes on plutonic hypabyssal batholiths laccoliths silts and dykes?

Answer 1

“A cactolith is a quasihorizontal chonolith composed of anastomosing ductoliths whose distal ends curl like a harpolith, thin like a sphenolith, or bulge discordantly like an akmolith or ethmolith.” This was said – tongue-in-cheek – by the USGS scientist Charles B. Hunt, in his paper about the Henry Mountains region, in 1953. He was in fact describing an actual geological feature – a laccolith which he saw as resembling a cactus – but he was also commenting on the absurd number of “-lith” words in the field of geology… We are not going that deep into the “lith”ology but can’t help mention a few of them.
