Re: a simple explaination of agate formation

Posted by: Alfred L. Ostrander

Thank you Jolyon for reconsidering your statement about agate as a rock. This is a situation where petrology and mineralogy should act hand in glove for the betterment of our understanding of quartz and its polytypes.

To the point of this posting. Mr Kasper, you have written a number of books about agates, geodes, etc. Many of your positions are well known and not agreed with. You do seem to have a habit of dropping some interesting lines.

Here is what Mr Kasper thinks on a few things.

Hardness and specific gravity have not been used in science since 1910 to identify minerals or rocks reported in the scientific literature.
There is a reason, and the reason is that those methods are grossly inaccurate.

Here is what Mr Kasper thinks of Mindat and Dana.

Oh well. I guess Mindat and the IMA is stuck in 1830, the age of Dana. It was such a simple world then. I see increasingly that our geology
books are more like history books of old science than real science. Many authors are lazy pigs, and quote that ancient data because it
keeps things simple, but the goal of science is to describe what we see and understand and understand with our best available data and
instrumentation, not the data of 1830. Dana is dead and the science has moved on.

Mr Kasper finished his post of Feb 21, 2013:

Lastly, I have never been ashamed of being smart.

I will also point out that on another posting, and I paraphrase, Mr Kasper made it clear to a researcher that when he had finished publishing as many books as he had, then they could compare notes.

Jolyon, if you wish, you can remove this. I am wondering if this thread should be closed.
