lasite

Could you please clarify what you mean by "lasite"? I’m not finding a widely recognized mineral or topic by that exact name in standard references. Do you want:

- a wiki-style article about a real mineral named lasite (if you have a source or locality),

- a fictional or speculative entry for a material called lasite,

- or a disambiguation-style note explaining possible uses of the term?

If you provide a source or intended context, I’ll generate a concise, neutral article under 300 words.
