Meaning of 「微細にわたる説明」


I'm looking at the definition of 微細 in different dictionaries. One dictionary
gives the example 微細にわたる説明. Does this mean "an explanation that barely gets
across," or does it mean something more like 説明は微細な点にまでわたる, which was an
example given in another dictionary.




微細 is used as a noun here (rather than the continuative/adverbial form of the
na-adjective 微細な) and means "details". 微細にわたる means "go into minute detail".
So...

> ［微細にわたる］説明 = An explanation ［that goes into detail］ (i.e. "A detailed
> explanation")
